Supreme Law and Supreme Inspection： Faking the websites of state organs to commit illegal and criminal activities will be punished.

　　Cctv newsToday (25th), the Supreme People’s Court and the Supreme People’s Procuratorate jointly held a press conference to release the Explanations of the Supreme People’s Court and the Supreme People’s Procuratorate on Several Issues Concerning the Application of Laws in Handling Criminal Cases such as Illegal Use of Information Networks and Helping Information Network Crimes. The Interpretation makes it clear that it will be a crime to set up a website for carrying out illegal and criminal activities in the name of a state organ or financial institution.

　　The Interpretation stipulates that if a website is set up to carry out illegal and criminal activities in the name of a state organ or financial institution, if the number of websites for carrying out illegal and criminal activities reaches more than three or the cumulative number of registered accounts reaches more than 2,000, it will be considered as "serious" and can be convicted.

　　Jiang Qibo, Director of the Supreme People’s Court Research Office.: If the number of communication groups used to carry out illegal and criminal activities reaches more than five, or the cumulative number of group members accounts reaches more than 1,000, or if the information related to illegal and criminal activities is released or for the purpose of carrying out illegal and criminal activities, it is considered as "serious".

　　In view of the fact that many cyber criminals, especially telecommunication network fraudsters, set up websites to carry out illegal and criminal activities in the name of state organs or financial institutions in practice, the Interpretation has set a lower threshold for conviction, so as to appropriately reduce the difficulty of obtaining evidence and truly realize the "early attack and small attack" on cyber crimes.

　　Jiang Qibo, Director of the Supreme People’s Court Research Office.For example, the Interpretation specifically stipulates that "setting up a website to carry out illegal and criminal activities in the name of a state organ or financial institution" constitutes "serious circumstances", that is, setting up such a website can constitute a crime.

　　The Interpretation stipulates that the illegal use of information network crimes with an illegal income of more than 10,000 yuan belongs to "serious circumstances". In addition, the Interpretation stipulates that those who have received administrative punishment for illegally using information networks, helping criminal activities of information networks, endangering the security of computer information systems within two years, and illegally using information networks, are "serious" and are sentenced to fixed-term imprisonment of not more than three years or criminal detention, and shall also be fined.

　　The Criminal Law stipulates that anyone who knowingly uses information networks to commit crimes, provides technical support such as Internet access, server hosting, network storage and communication transmission, or provides assistance such as advertising promotion and payment and settlement, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention, and shall also or shall only be fined. The new judicial interpretation clarifies the presumption rule of subjective knowledge of the crime of helping information network criminal activities.

　　According to the criminal law, it constitutes the crime of helping information network criminal activities, which requires the perpetrator to "know that others use information network to commit crimes" subjectively.

　　Jiang Qibo, Director of the Supreme People’s Court Research Office.According to the situation of judicial practice, the Interpretation summarizes and clarifies the presumption of subjective knowledge of the crime of helping information network criminal activities, that is, providing technical support or help for others to commit crimes. Under any of the following circumstances, the perpetrator can be deemed to know that others are using information network to commit crimes, unless there is evidence to the contrary.

　　Presumption of subjective knowledge of the crime of helping information network criminal activities: (1) The relevant acts are still carried out after being informed by the regulatory authorities; (2) Failing to perform the statutory management duties after receiving the report; (3) The transaction price or method is obviously abnormal; (4) providing programs, tools or other technical support and assistance specially used for illegal crimes; (5) Frequent use of hidden Internet access, encrypted communication, data destruction and other measures or use of false identities to evade supervision or investigation; (6) Providing technical support and assistance for others to evade supervision or investigation; (7) Other circumstances that are sufficient to determine that the perpetrator knows.

　　Criminals who illegally use information networks can be banned from occupation.

　　How to prevent cyber criminals from "returning to their old jobs"? The judicial interpretation issued today has also been clarified. The Interpretation stipulates that criminals who illegally use information networks can declare occupational prohibition and prohibition orders according to law.

　　According to the provisions of the Criminal Law, if a person commits a crime by taking advantage of his occupation, the people’s court may, according to the situation of the crime and the need to prevent recidivism, prohibit him from engaging in related occupations from the date of execution of the penalty or the date of parole for a period of three to five years; Sentenced to public surveillance or suspended sentence may, according to the circumstances of the crime, prohibit criminals from engaging in specific activities during the execution period. Jiang Qibo, director of the Research Office of the Supreme People’s Court, said that in view of the fact that cyber crimes are committed again to a considerable extent and many criminals "return to their old jobs", the Interpretation specifically stipulates that criminals who refuse to fulfill their obligations of information network security management, illegally use information networks and help information network criminal activities can declare occupational bans and restraining orders according to law.

　　Jiang Qibo, Director of the Supreme People’s Court Research Office.: "If a person is sentenced to punishment for committing a crime as stipulated in this Interpretation, he may declare the occupational ban according to the situation of the crime and the need to prevent recidivism; If a person is sentenced to public surveillance or suspended sentence, he may declare an injunction according to the circumstances of the crime. "

　　Online payment causes user information disclosure or criminal responsibility.

　　It is the premise and foundation of maintaining network security for network service providers to fulfill their obligations of information network security management stipulated by laws and administrative regulations. The "Interpretation" clarifies that a network service provider who refuses to perform the obligation of information network security management and refuses to make corrections after being ordered by the regulatory authorities, resulting in the disclosure of more than 500 pieces of track information, communication content, credit information and property information, will be convicted.

　　Explain that the scope of "network service providers" includes units and individuals that provide the following services:(1) Information network access, calculation, storage and transmission services such as network access and domain name registration and resolution; (2) Information network application services such as information release, search engine, instant messaging, online payment, online reservation, online shopping, online games, online live broadcast, website construction, security protection, advertising promotion, application stores, etc.; (3) Public services such as e-government, communication, energy, transportation, water conservancy, finance, education and medical care provided by information networks.

　　The above-mentioned units or individuals, through the departments of network information, telecommunications, public security, etc., order the network service providers to take corrective measures in the form of rectification notices or other documents, and refuse to make corrections. If there are serious circumstances, it constitutes a crime.

　　Jiang Qibo, Director of the Supreme People’s Court Research Office.In order to unify the judicial application, the Interpretation defines the criteria for the crime of refusing to perform the obligation of information network security management according to different situations.

　　The "Interpretation" issued this time clarifies the above-mentioned criteria for conviction, and refines "causing a large amount of illegal information to spread" into:Causing the dissemination of more than 200 illegal video files; Causing the dissemination of more than 2,000 illegal information other than illegal video files; Seven situations, such as the actual number of hits on illegal information reaching more than 50 thousand. The situation that will lead to the disclosure of user information and cause serious consequences is clearly defined as: causing the disclosure of more than 500 pieces of track information, communication content, credit information and property information; Causing the disclosure of more than 5,000 pieces of user information, such as accommodation information, communication records, health and physiological information and transaction information, which may affect personal and property safety; Eight situations that cause serious consequences such as death, serious injury, mental disorder or kidnapping of others.

　　On the afternoon of 27th local time, an important Iranian nuclear physicist, Fahrizad, was assassinated near Tehran. Iran’s Supreme Leader Ayatollah Ali Khamenei on 28th demanded that those involved in the killing of Fahri Zadeh be punished. Iranian Foreign Minister Zarif said that "significant signs" indicated that the Israeli-affiliated Fahri Zadeh was attacked.

　　Israel declined to comment on the attack on Fahri Zadeh. A spokesman for the Israeli Foreign Ministry said that Israel would not comment on the safety of foreign missions. Israeli media reported that after Iran threatened to retaliate, Israeli embassies around the world entered a state of high alert. (Overseas Network Li Fang)

Highlight analysis, car cost and purchase recommendation of Tesla Model Y model

Model Y is a pure electric SUV made in China by Tesla brand. Everyone is certainly not too strange to Tesla brand. According to the SUV sales ranking of Zhiche Di in November 2021 (sales come from the Association), Model Y can be said to be a sudden emergence, and it is indeed a bit eye-catching in the "encirclement" of a number of fuel SUV models. Today, let’s briefly talk about Tesla Model Y.

Tesla Model Y is a pure electric SUV officially launched in China in January, 2021, and the vehicle configuration was adjusted in November and December, 2021. At present, there are three models on sale, with the price range of 291,800-387,900 yuan, of which the 2022 Model Y rear-wheel drive version with the price of 291,800 yuan can enjoy subsidies, and the subsidized price is 280,800 yuan. This is an individual purchase. If it is purchased by a non-individual, the subsidy amount will be less, and if the user chooses to install other configurations when purchasing Model Y, and the price will exceed 300,000 yuan, he will not be able to enjoy the new energy subsidy.

The three models of Model Y are the 2022 Model Y rear-wheel drive version with a price of 280,800 yuan, the 2022 Model Y long-life all-wheel drive version with a price of 347,900 yuan and the 2021 Model Y Performance high-performance all-wheel drive version with a price of 387,900 yuan. The actual selling price will change because users choose different installation configurations. For example, the white pearl paint in the above picture needs an optional price of 8,000 yuan. The current price is for reference only, and the items that have an impact on the price are vehicle color, wheel hub, interior color matching and driver assistance function package.

The front face design takes the 2021 Performance high-performance all-wheel drive version as an example. The front face design is almost the same as Tesla’s hot-selling pure electric car Model 3, and the front face as a whole is a relatively simple style, with a closed front grille design and polygonal headlights design. Compared with the increasingly large air intake grille of fuel vehicles, the closed grille of Model Y is still relatively "eye-catching". There are two 7-shaped fog lights at the front enclosure, and with the trapezoidal air intake, the front face has a "anthropomorphic" feeling.

The measurements of Model Y are 4750x1921x1624mm and the wheelbase of the vehicle is 2890 mm.. The length of 4.75 meters and the width of more than 1.9 meters make the real car of Model Y feel relatively large. Model Y adopts a streamlined roof and a large sliding back design. The roof curve extends from A-pillar to the rear of the car, which is visually smooth and close to the coupe SUV model. The tail of the vehicle is high, and the front of the vehicle is pressed down, so that the visual center of gravity of the whole vehicle moves forward and the sense of dive is obvious.

Model Y is equipped with tires and wheels of various sizes. The 2022 Model Y rear-wheel drive version uses 255/45 R19 Hankook tires matched with 19-inch Gemini wheels. If you don’t like Gemini wheels, you can also directly choose blackened induction turbine wheels (pictured above). The 2021 Model Y Performance high-performance all-wheel drive version uses 255/35 R21 Pirelli tires matched with 20-inch induction turbine wheels.

The tail design of Model Y is similar to that of Model 3. Simply looking at the upper part of the tail, Model Y is the same as Model 3. Unlike Model 3, Model Y has a larger area surrounded by a black fender, and the rear fog lamp of Model Y is integrated above the fender, while Model 3 is at the rear bumper. Other designs are basically the same.

Entering the interior, the interior of Model Y is mainly simple, and there are almost no redundant interior design elements except the 15-inch large screen in the central control. The center console uses wooden boards and matte chrome trim strips to enhance the atmosphere inside the car. All the vehicle functions in the car are concentrated in the 15-inch multimedia screen, including the functions of side and rear camera images, car navigation, movies, music, games and so on. The interior seat material has a delicate touch, and is made of low-volatility, environmentally-friendly material, which is more resistant to dirt and durable. In addition, if the user likes the simple and elegant feeling, Model Y also supports the optional black and white two-color interior design, which can be considered by users with sufficient budget.

In terms of details, the front seat of Model Y is more comfortable, and the lumbar support and shoulder support on both sides of the seat are relatively small, which makes the driver feel less wrapped. With a wheelbase of 2890mm, the legroom performance in the car is still good, but the disadvantage is that the cushion is not thick enough. Considering the design of Model Y’s large slip-back roof, a thinner cushion will be more friendly to the head space. The roof is equipped with a large panoramic canopy, which can bring a brighter ride experience to the passengers. In addition, the central passage of the vehicle is equipped with a wireless charging module with double bases, which is made of non-slip suede material, so that two mobile phones can be wirelessly charged at the same time, the charging power is also increased to 7.5W, and the wireless charging speed is also improved.

Model Y is also equipped with front and rear seat heating, steering wheel heating, HEPA air filtration system, 14-speaker audio system, immersive sound effects and other functions, so I won’t repeat them one by one.

Model Y has three configurations. The entry configuration is the 2022 rear-wheel drive version with a price of 280,800 yuan (after individual user subsidies). The rear-wheel drive version is driven by a rear permanent magnet synchronous single motor with a total motor power of 202kW, which can output a total torque of 404 N m. Although it is a single motor version, the acceleration time from 0 to 100 km/h is 6.9 seconds, and the maximum speed can be driven to 217 km/h. The rear-wheel drive version is powered by lithium iron phosphate batteries, with a battery capacity of 60kWh. Tesla implements a battery warranty policy of 8 years and 160,000 kilometers. The advantage of lithium iron phosphate batteries is that the battery charge and discharge cycles are more than those of ternary lithium batteries, that is, the battery life is longer. The battery life of the 2022 rear-wheel drive version is 545km when tested by CLTC, and the battery life beyond 500 kilometers is enough for daily use.

Model Y is equipped with a 2022 Model Y long-life all-wheel drive version with a price of 347,900 yuan. The long-life all-wheel drive version uses front and rear dual motor power, and the front motor uses an induction asynchronous motor with a total motor power of 137kW and a total motor torque of 219N·m；; The rear motor adopts permanent magnet synchronous motor, with a total motor power of 194kW and a total motor torque of 340N·m, a total motor power of 331kW and a total motor torque of 559 N m. Simply looking at the power data, it is really powerful. The acceleration time of 0-100 km/h for the long-life all-wheel drive version is 5 seconds, which has surpassed many fuel version performance models. The maximum speed of the vehicle is the same as that of the rear-wheel drive version, which is 217 km/h.

The long-life all-wheel drive version uses ternary lithium battery pack as the motor power supply, and the battery pack capacity is 78.4kWh. Tesla provides it with a long warranty policy of 8 years and 192,000 kilometers. Compared with lithium iron phosphate battery pack, ternary lithium battery pack has higher tolerance for low temperature environment, which is more suitable for use in low temperature environment in winter, so it is more suitable for users in northern China to purchase. The cruising range of the 2022 long-endurance all-wheel drive version tested by NEDC standard is 640km, which is nearly 100km longer than that of the rear-wheel drive version, and it is more practical. If the budget allows, users are advised to choose the 2022 long-endurance all-wheel drive version, which has better performance in power and endurance.

Model Y is a 2021 Model Y Performance high-performance all-wheel drive version with a price of 387,900 yuan. The high-performance all-wheel drive version also uses front and rear dual motor power, and the front motor uses the same induction asynchronous motor as the long-life version. The total motor power is 137kW and the total motor torque is 219N·m；; The rear motor also adopts permanent magnet synchronous motor, but the motor power is slightly different. The total motor power is 220kW, the total motor torque is 440N·m, the total motor power is 486kW, the total motor torque is 659N·m, and the 0-100 km/h acceleration time of the high-performance all-wheel drive version is 3.7 seconds. This acceleration time has reached the level of super sports car, and the power performance is beyond doubt.

The high-performance all-wheel drive version also uses ternary lithium batteries as the motor power supply, and the battery capacity is 76.8kWh. The ternary lithium batteries have high charging and discharging efficiency, which is more suitable for the high-performance version. Tesla provides it with a long warranty policy of 8 years and 192,000 kilometers. The 2022 high-performance all-wheel drive version has a battery life of 566km, which is enough for daily use.

But if it is just a means of transportation, isn’t the power of the high-performance version "wasted"? If you use it daily, the performance of the long battery life version is enough to meet the daily needs. It is recommended that users give priority to the long battery life version or the rear-wheel drive version.

For electric car owners, charging is the primary problem in car use. One of Tesla’s advantages to attract users is the brand-supporting super charging station. Model Y supports fast charging (overcharge). It takes 10 hours for Model Y to charge slowly with alternating current from 0-100%, and 1 hour for fast charging with direct current from 0-80%. If Tesla V3 super charging station is used for charging, it will be 15 minutes at the peak power under ideal conditions.

When it comes to the V3 super charging station, its peak charging power is 250kW. As a comparison, the charging power of the DC fast charging of the State Grid is generally around 40kW (which is also constantly upgrading). By comparison, even if Model Y entering the V3 super charging station is not in an ideal state, the charging power is affected to some extent. Assuming that the charging power is maintained at 70% of the peak power, it can reach the charging power of 175kW, which is much higher than that of the DC fast charging of the State Grid.

At present, more than 9,500 Tesla brand V3 super charging stations and the previous generation V2 super charging stations have been built around the world, and they are still increasing at a faster speed. In addition, Tesla has also launched a "destination charging" program, which can cooperate with some restaurants, restaurants and shopping centers to build charging facilities in the potential "destinations" of these users to facilitate users to charge. As for the charging cost of the super charging station, Tesla owners have a free charging quota of 400kWh per year, and the excess will be charged according to 1.8 yuan /kWh (which will be slightly adjusted according to local conditions). In addition, users can install their own AC slow charging piles to charge Model Y, and the electricity tariff policy of different peak and valley electricity prices of the State Grid will not lead to high actual electricity consumption.

In terms of maintenance, although Model Y does not need to change the engine oil, it also needs regular inspection and maintenance to ensure the safety of the vehicle. According to the "Tesla Vehicle Maintenance Plan", it can be seen that the items and expenses that Model Y needs to be replaced and maintained are as shown above. To replace the air conditioning filter and brake fluid of the vehicle, it is generally inspected and maintained once a year or 20,000 kilometers. According to the 8-year prepaid package, The average cost per trip is 3,835 yuan (15,300 yuan /4 trips = 3,835 yuan), but if the maintenance frequency of fuel vehicles is 10,000 kilometers, the cost of Tesla in the same cycle is 1,912.5 yuan (15,300 yuan /8 trips = 1,912.5 yuan), which is relatively less than that of luxury brand models with the same price. Besides changing brake fluid, air conditioning overhaul and battery coolant, you can do it yourself, and the actual cost will be less.

Through the above explanations, I believe that everyone has a certain understanding of the highlights of Tesla Model Y. From the sales in November, Model Y has its own highlights in the SUV sales list. In my opinion, Model Y does have its own uniqueness in the three-electric system, cruising range and complete super charging station. If you are interested in Tesla Model Y, go to the store and experience it.

I want to buy the classic Sylphy 1.6L Comfort Edition. How much is the full price？ Is home worth buying？

In recent two years, the involution of the automobile market is obvious to all. Especially for new energy vehicles, "backstab old car owners" have become a common occurrence. However, some old joint venture car companies that have not kept pace with the new energy market can only maintain their market share through continuous price reduction, and the price reduction rate is also staggering. Think about the previous price, there is really a feeling that can’t be said.

800x600_1_autohomecar__ChxoHWYHy3mAabHsAAWKk0Tpxmw810

Yesterday, fans left a message saying that they wanted to buy 24 Nissan classic 1.6L XE CVT comfort versions, and asked the 4S shop for a discount of 30,000 yuan. I want to ask how much more discount I can talk about. I thought the 30,000 discount was big enough, but when I learned about the market from professional channels, I found that the discount was 40,000. This discount really shocked me. It seems that the Qin Glory Edition from 79,800 can really play!

QQ picture 20240401190905

Let’s talk about the price first. Sylphy 2024 classic 1.6L XE CVT comfort edition, the manufacturer’s guide price is 108,600 yuan, the terminal discount is 40,000 yuan, the naked car price after the discount is 68,600 yuan, the vehicle insurance is about 4,500 yuan, the vehicle purchase tax is 6,070 yuan, and the license fee is 300 yuan, and the full price is 79,470 yuan (the above prices are for your reference only, and the actual price is subject to the local dealer).

800x600_1_autohomecar__ChxoHmYHy4GAUje_AAYOF9ZPhdQ662

The reason why it is called the 2024 Classic Edition is that this model is exactly the same as the 2020 classic model, which is equivalent to selling the products in 2020 in 2024. Although this car has not changed in the past four years, the development of our own brand new energy can be described as changing with each passing day, so it is impossible to compete with independent new energy models without a substantial price reduction.

800x600_1_autohomecar__ChtlyGYHy4SADAB9AAV7614tKVI560

I don’t need to introduce the design of the classic Sylphy. The v-motion family-style front face design is quite satisfactory, and the headlights are still halogen light sources, not equipped with front fog lights. Although the side of the car body is an entry-level model, a circle of chrome-plated decorative strips is used around the window, and aluminum alloy wheels are also used. The tire size is 195/60 R16. In terms of the rear end, I personally don’t particularly like the classic version of Sylphy’s rear end design, and I feel particularly narrow.

The design of the central control in the car can only be described by classic words now. After all, the large-scale physical buttons of the entire central control are no longer used by many new energy vehicles and our own brands. However, on one point, I still suggest that it is better to use physical design for more car companies’ air conditioning buttons and danger warning light buttons, because these two buttons are very useful at critical moments and can be operated blindly.

Combined with the landing of the classic business entry model, I think this central control configuration is still acceptable. In the later stage, everyone can upgrade a color screen by spending 1000~2000 yuan. At the lower left of the steering wheel, we can see that this car is equipped with a body stabilization system and an ECO economic mode switch button, and it is also equipped with six airbags. Although the seat is made of fabric, personally speaking, the comfort is good.

In terms of space, the length, width and height of this model are 4631×1760×1503mm and the wheelbase is 2700mm respectively. From the body size, it is a standard compact car. My height is 1.88 meters and my weight is 90 kilograms. After adjusting my normal driving posture in the front row, I can’t get a punch into the leg space in the second row. I think my performance is ok among the models of the same class.

44bbdeec69983ca461d214380d40d3fe~2508x0.webp

In terms of power, the car is equipped with a 1.6L naturally aspirated engine of engine model HR16, with a maximum power of 122 HP and a maximum torque of 155 Nm. The fuel supply mode of the mobile phone is multipoint injection, and the cylinder head and cylinder block of No.92 gasoline are made of aluminum alloy. This engine technology is not particularly advanced, but now it is particularly stable and fuel-efficient, and the CVT gearbox is matched with it, which focuses on smooth and fuel-efficient.

800x600_1_autohomecar__ChxoHWYHy32AQVCtAAUVcaC8Pz0313

My opinion:If we look at the classic Sylphy from the perspective of examining new energy vehicles, we will think that this car has been derailed from the times, but think about it again. The market of family cars of 600,000 ~ 100,000 class every year is still very huge. More families have mileage of cars around 10,000 kilometers each year, and some of them are less than 10,000 kilometers. If you buy a car, it is a down-to-earth home, and considering the subsequent stability, then this classic Sylphy is really worth considering (the picture in the article comes from the network).

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

The function of automobile cooling system is to dissipate the heat in time to make the engine work at the most suitable temperature. The ideal automobile cooling system should not only meet the needs of engine cooling, but also reduce heat loss and energy consumption, so that the engine can have better energy-saving effect on the basis of ensuring good power performance.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

First, the working principle of the cooling system

The cooling system plays a very important role in the automobile. The engine cooling system generally adopts water cooling. The typical cooling system consists of radiator, radiator hose, thermostat, water pump, cooling fan and fan belt.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

It relies on the cooling water pump, flows through the oil cooler and crankcase cooling water jacket, enters the cylinder head, and takes away the excess heat of the engine.

Great cycle:When the engine works under normal thermal state, that is, the water temperature is higher than 80℃, the cooling water should all flow through the radiator to form a large cycle. The main valve of the thermostat is fully opened, while the control valve completely closes the bypass hole.

Small cycle:When the cooling water temperature is lower than 70℃, the steam pressure in the expansion tank is very small, and the cooling water does not flow through the radiator, but only circulates between the water jacket and the water pump.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

Second, the role of coolant

Coolant plays a very important role in the normal operation of the engine. Too high or too low coolant temperature will have an adverse impact on the engine. If the engine coolant temperature is too high and the viscosity of lubricating oil decreases, the friction loss of engine parts will increase.

If the engine coolant temperature is too low, the viscosity of lubricating oil will increase and the fluidity will deteriorate, which is also not conducive to lubrication, thus reducing the power output of the engine and affecting the mechanical efficiency of the engine.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

Coolant is the heat transfer medium in the cooling system, which has the functions of cooling, anti-corrosion, anti-scaling and anti-freezing. It is composed of water, antifreeze and various additives.

1. Water is an important part of cooling liquid, which has large specific heat capacity and fast heat conduction, and the heat absorbed by water is easy to dissipate.

2. Antifreeze is used to reduce the freezing point of coolant. Because of the high freezing point of water, it is easy to freeze when used in cold and low temperature weather. Adding a certain amount of antifreeze can reduce its freezing point and meet the harsh working conditions.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

3. Other additives

Additives generally do not exceed 5%, mainly corrosion inhibitors, buffers, scale inhibitors, defoamers and colorants.

(1) Corrosion inhibitor:It can effectively prevent the corrosion of metal substances in the cooling system, because the cooling pipeline is mainly composed of metal parts, and it is easy to corrode under the conditions of high pressure, thermal load and corrosive medium, which will damage the cooling system.

(2) Scale inhibitor:It can effectively remove the scale and improve the heat dissipation capacity. During the use of cooling liquid, scale often forms on the inner surface of the cooling system, and the thermal conductivity of scale is lower than that of metal, which seriously affects the normal heat dissipation.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

(3) Defoamer:It can effectively prevent foaming. When the coolant is forced to circulate under the high speed of the water pump, it usually produces foam. A large amount of foam not only affects the heat transfer efficiency, but also aggravates the cavitation corrosion of the water pump.

(4) Colorant:In the process of using coolant, it is generally required to add certain coloring agent to make the coolant have eye-catching color. In this way, when the cooling system fails, the location of leakage can be easily judged by observing the external pipeline of the cooling system.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

Third, the classification of coolant

Engine coolant is divided into ethylene glycol coolant and propylene glycol coolant according to antifreeze:

1. The specific heat capacity, thermal conductivity, viscosity and boiling point of ethylene glycol are all important parameters that affect the heat transfer performance of ethylene glycol aqueous solution. The specific heat capacity and thermal conductivity of ethylene glycol aqueous solution decrease with the increase of concentration, while the viscosity increases with the increase of concentration.

2. The performance of propylene glycol in reducing freezing point is basically the same as that of ethylene glycol, and it is less toxic and more expensive than ethylene glycol.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

Fourth, the maintenance of the cooling system

1. Selection of coolant

(1) In order to prevent the cooling system from freezing, appropriate antifreeze can be selected. Generally, the freezing point of antifreeze should be 5℃ lower than the lowest temperature in the use area.

(2) Different types of antifreeze cannot be mixed.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

2. Replacement cycle and dosage

(1) Replacement cycle:Generally, the coolant needs to be replaced once every 2-3 years, specifically according to the instruction manual.

(2) Addition dosage:The antifreeze should be added between the marks F(MAX) and L(MIN) of the expansion tank in the engine cooling state.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

3. Daily maintenance:

(1) Pay more attention to daily observation. Once the coolant is insufficient, the surface of the water pipe shows signs of whitening or there is white emulsion in it, the coolant leaks.

(2) Check the connection position and state of all cooling system hoses and heater hoses, and replace them in time if they swell or deteriorate.

Heavy truck cooling and heat dissipation know how much coolant is the most critical.

Summary: The cooling system plays a very important role in the car. In daily use, Ying Qin should take care of it to prevent problems before they happen and keep the car in a good state. Always check whether the engine coolant is sufficient, and add or replace the appropriate coolant in time when necessary.

Esther Yu’s way of speaking is too artificial, but he succeeded in attracting enough attention.

Esther Yu speaks.

Original title:"Youth has you 2" Esther Yu speaks. Is Esther Yu’s family rich?

Are Esther Yu and Zhao Zhiwei still together?
Now, the second season of "Youth with You" has finally begun, and several program-related entries are not surprisingly listed in Weibo hot search, and Qing 2, who has been saving her strength for so long, can be regarded as a good start.

However, the draft is always accompanied by controversy. This time, the tone of Esther Yu, a junior 2 player, became the biggest topic of the first program.

In this program, Xiao Bian’s first impression of her actually comes from the sentence "This practice is less than a month" said by Ella’s tutor.

I believe many people have such a question, are you sure this is not for soy sauce or eyeballs?

After all, as an actress, coupled with the just-hit film and television drama, it is hard not to make people think so.

Although other trainees will not spend four or five years, they will not stand on this stage in just one month, will they?

Esther Yu speaks.

Although Xiao Bian likes Cai Minmin, who plays her role in "The Next Stop is Happiness", as the saying goes, interlacing is like a mountain. For this draft, Xiao Bian does not have much expectation for her.

But what people didn’t expect was that Esther Yu’s next interaction was surprising.

Some people may think that this is a kind of cuteness that belongs to her, but more people still think that it is too artificial, and they have given her a new name "Xiaozuojing", which is unbearable to listen to, and this sense occupies the vast majority of the audience.

As far as Xiaobian is concerned, I also think it is a little small.

From her entrance to the interaction with the tutor, to being next to Jony J on her own initiative, her deliberate performance is still a bit too obvious, no matter her eyes, tone or movements.

This way of speaking may attract enough attention, but it is obviously not understood and accepted by the public.

Especially after expressing the position of wanting to be JONY J’s teacher, it gives people a very rude feeling.

Esther Yu speaks.

Courier industry competition! Not only for majors, but also for classical Chinese and English？

　　"Hello, please show me your ID card." After scanning the ID card, the courier Li Qingheng began to pack the items on the table, including glass goblets, books, mobile phones, table tennis, lighters and USB flash drives. According to the requirements, these items need to be sent to other places by air. Li Qingheng first took out the battery in his mobile phone, and he also pulled out a RMB from the book, which, like table tennis, lighters and USB flash drives, cannot be sent by air.

　　Recently, the preliminary contest of the 3rd Zhejiang Express Vocational Skills Competition and the 2nd National Postal Industry Vocational Skills Competition was held in Zhejiang Vocational and Technical College of Posts and Telecommunications. Thirty-six courier brothers from 11 express delivery companies in our province participated in the competition. In the end, Shen Tong’s younger brother Li Qingheng and Shun Feng’s younger sister Zhang Chuxue won the first place as couriers and express handlers respectively. They and other outstanding younger brothers will have the opportunity to represent Zhejiang in the national finals in October this year.

　　What do you test in the courier competition? How did they behave? The reporter walked into the scene of the exam.

　　Theoretical knowledge is like an encyclopedia.

　　Not only for majors, but also for classical Chinese and English

　　"According to the national standard of Express Service, the total number of personnel in the headquarters and branches of express service organizations operating inter-provincial express delivery business should be no less than how many?" "What is the basic compensation principle for express delay?" The reporter noticed that the competition project consists of two parts: theoretical knowledge competition and practical operation competition. Theoretical knowledge includes basic knowledge, professional knowledge, new knowledge and new technology, etc. The questions are single-choice, multiple-choice and true-false questions, accounting for 30% of the total score.

　　Many courier brothers told reporters that this theoretical examination was quite comprehensive. In addition to professional knowledge, for example, there are some topics like encyclopedias — — "Tianhe International Airport is located in which of the following provinces?" "What is the aviation code of Melbourne International Airport?"

　　What makes a little brother dumbfounded is that "the ancients called ‘ I save myself three times a day ’ What does it mean? " "Henan ‘ Yancheng ’ How should I read it? " There is even an English question: "Here is your change．. What is the most accurate translation of this sentence?"

　　Although the impression to outsiders is that the overall education level of the industry is not high, the theoretical performance of this year’s little brother is good as a whole, with a perfect score of 100 points and more than 80 points everywhere. The courier with the highest score got 91 points.

　　Practical operation test details

　　Designing delivery routes is the most difficult.

　　After passing the theoretical test, I entered the practical link. What items can’t be transported by air? How many steps does it take to put the parcel into the express cabinet? These are the key points of investigation.

　　According to the two types of work, courier and express handler, the younger brothers should carry out express security inspection, general contractor receiving and processing, express sorting, intelligent express box delivery, multi-item receiving and sending, delivery line design, etc. This part of the score accounts for 70%.

　　Although these operations are daily for the courier brother, it is easy to fall into the "trap" if you are not careful.

　　Li Qingheng is 24 years old. Three years ago, he jumped ship from a western restaurant and joined the express delivery industry. "I work in the provincial transshipment center every day and am responsible for the handling of problem pieces." As a courier, Li Qingheng is confident in packing. "I picked out all the prohibited items, including glue stick, USB flash drives, lighters, RMB and table tennis. The only regret is that I was too nervous at first, and I packed some items in a hurry, only to find that there was also an environmentally friendly sealing tape on the table. " Li Qingheng told reporters that according to the relevant regulations of the state on green packaging, the packaging link should be as green and light as possible. Even the environmentally friendly sealing tape, sometimes it is enough to pack one word, and there is no need for a cross or a pound sign.

　　Xiao Qidong, the younger brother of Zhongtong, told the reporter that there are many traps in the express cabinet. First of all, before the package is put in, you should contact the recipient first, and make sure that the phone number of the recipient on the face sheet is the same as the phone number read by the express cabinet. Otherwise, you should contact the recipient first to verify the correct information. There is also a certain emphasis on which cabinet the package is put in. In addition to being as economical as possible, the weight of each compartment is also limited.

　　Perhaps the most difficult part is the design of the delivery line. "To complete the delivery route design of 19 tickets within 12 minutes, we must first deliver the ones with timeliness requirements. In addition, we also take the optimal route to avoid duplication." Li Qingheng tried many times and came up with the best plan.

　　After 90, Miss Express became the first place.

　　The hardest thing is not physical strength but communication.

　　In many people’s impression, express delivery is a physical activity, and most people engaged in the express delivery industry are men. However, Zhang Chuxue, a 90-year-old sister from SF, won the first place as a courier handler in this competition, weighing only over 80 kilograms. Many people did not expect that a small figure could have such great energy and stand out among many male contestants and become a leader.

　　Zhang Chuxue told reporters that his first choice to fill in the college entrance examination was not express management, and he entered this business by mistake. "The main content of the usual work is warehouse management. The sorting comes from the general contractors in various provinces, and the heaviest one is dozens of pounds. Although I can sometimes find a male colleague to help me, I still need to move it myself most of the time."

　　Daily sorting over and over again made Zhang Mengxue "lose a few pounds" and made her get the highest score in the competition of receiving and handling by the general contractor. In Zhang Mengxue’s view, the hardest thing is not physical effort, but communication with customers.

　　"I was deeply impressed that once because of the snow, the express delivery was blocked for more than ten hours on the high speed, which led to the late aging, and people just didn’t listen." Zhang Chuxue said that fortunately, everyone’s understanding of courier brother is getting higher and higher now. "I will continue to work in this industry and do a good job."

　　According to reports, this competition is sponsored by Zhejiang Postal Administration, Zhejiang Provincial Department of Human Resources and Social Security, Zhejiang Federation of Trade Unions, Zhejiang Provincial Committee of the Communist Youth League, undertaken by occupational skill testing authority and Zhejiang Vocational and Technical College of Posts and Telecommunications in Zhejiang Province, and guided by the Vocational Skills Appraisal Guidance Center of the State Post Bureau.

　　According to statistics, the volume of express mail in Zhejiang Province exceeded 10 billion pieces last year, with nearly 300,000 employees. (qianjiang evening news correspondent Li Xiang qianjiang evening news reporter Chen Wei)

A-share salary competition in the first half of the year： Are the top 10 companies throwing billions for employees sour？

　　Zhongxin Jingwei Client August 17th (Dong Xiangyi) In the past two days, the news that "the average monthly salary of Tencent employees is 72,700" has been screened on the Internet, and netizens have become "lemon essence" in seconds — — "I am on average with Ma Huateng, and I am also a person with hundreds of billions of dollars." Jokes are jokes, but the high salary of Tencent employees is really beyond the reach of people in the financial circle and IT circle. Looking at the whole country, the figure of 72,700 yuan even exceeds the sum of the per capita disposable income of Shanghai and Beijing in the first half of this year.

　　Generally speaking, how much employees earn is inseparable from the performance of enterprises. The latest financial report shows that Tencent’s net profit in the second quarter of this year was 23.5 billion yuan, a year-on-year increase of 19%, far exceeding market expectations. BATJ has always been a leader in the Internet industry, and it is not surprising to offer a high salary in order to attract talents widely. In the A-share market, which industry makes the most money? Historical data show that finance and real estate have always been "gold-sucking" industries, and executives at the top of the pyramid are also the most profitable, with annual salaries ranging from tens of millions of yuan to nearly one million yuan.

　　According to the analysis of Sino-Singapore Jingwei client, as of 15:00 on August 16th, in the first half of 2019, the total cash paid to and for employees by 648 A-share companies that have published semi-annual reports was 266.17 billion yuan. In terms of total amount, China Ping An ranked first with 45.14 billion yuan, followed by China Unicom and Ping An Bank, with 20.66 billion yuan and 11.24 billion yuan respectively. According to statistics, the top 10 A-share companies paid employees a total of 114.93 billion yuan.

　　It is worth noting that because the number of employees and the pace of accrual are different in each enterprise, enterprises with a large total salary may not have a high monthly salary per capita, and enterprises with a small total salary may not have a low monthly salary per capita.

　　Who is the most generous?

　　The financial report of listed companies can’t find the total amount of salary paid by enterprises to employees. The client of Sino-Singapore Jingwei has selected the financial index of "paying employees and cash paid for employees" on Wind, which includes: wages, bonuses, various allowances and subsidies actually paid to employees in this period, as well as social insurance funds, supplementary pension insurance and housing accumulation fund paid for employees.

　　Wind shows that as of 15:00 on August 16th, in the first half of 2019, the total cash paid by 648 A-share companies that have published semi-annual reports to their employees was 266.17 billion yuan, and the top three companies, China Ping An, China Unicom and Ping An Bank, all exceeded 10 billion yuan, among which China Ping An paid employees 45.14 billion yuan, far ahead.

　　According to the rough calculation of the Sino-Singapore Jingwei client, the average monthly salary of China Ping An employees is 20,000 yuan. The average monthly salary of employees of China Unicom and Ping An Bank is 14,000 yuan and 56,000 yuan respectively.

　　In addition, Industrial Fulian, Huaxia Bank, Huaneng International, Hikvision, Kweichow Moutai, Poly Real Estate and Shanghai Port Group rank among the top ten, and the top 10 A-share companies pay a total of 114.93 billion yuan. The industries distributed by the above companies involve telecommunications services, finance, real estate, electronics manufacturing and so on.

　　On August 15, China Ping An released the semi-annual report for 2019. In the first half of the year, the net profit returned to the mother was 97.68 billion yuan, a year-on-year increase of 68.1%, and the high performance was in line with expectations; In the first half of the year, the operating income was 639.15 billion yuan, up 19.2% year-on-year; The dividend per share was 0.75 yuan, compared with 0.62 yuan in the same period last year.

　　Minsheng Securities believes that the two main contributions of China Ping An’s high performance growth in the first half of the year are as follows: First, tax cuts are favorable for cash. Non-recurring profit and loss items are positively promoting net profit. The report shows that the one-time tax adjustment of the company has a positive impact on the current net profit of 10.453 billion yuan. After excluding the impact, the non-net profit attributable to the parent company increased by 50.6% year-on-year. Second, the stock market performed well in the first half of the year. In the first half of the year, China Ping An achieved a year-on-year increase in investment income of 31.4%.

　　China Unicom, which won the second place, disclosed the semi-annual report for 2019 on August 14th. During the reporting period, the company achieved operating income of 132.96 billion yuan, down 1.1% year-on-year. The net profit attributable to the parent company was 3.02 billion yuan, a year-on-year increase of 16.08%. Among them, the operating income and net profit in the second quarter were 71.81 billion yuan and 1.39 billion yuan respectively, the former decreased by 3.2% year-on-year, while the latter increased by 8.6% year-on-year. It is reported that the decline of China Unicom’s operating income is mainly affected by the decline of mobile communication business income, and the increase of the company’s net profit is mainly caused by insisting on differentiated operation, vigorously changing to Internet operation, controlling costs and improving efficiency.

　　Who is the most "shabby"?

　　There are listed companies that are generous to employees, and there are also listed companies that are slightly shabby. The Zhongxin Jingwei client combed and found that in the first half of 2019, ST Hongsheng and ST Xiahua "joined hands" at the bottom, and the cash paid to employees and for employees was 2.462 million yuan and 2.523 million yuan respectively.

　　Recently, ST Hongsheng released the semi-annual report for 2019. According to the data, during the reporting period, the company achieved operating income of 12.056 million yuan, down 13.3% year-on-year, mainly because the company stopped operating the water environment restoration business, while the automobile interior business was still in its infancy, and the income scale still needs to be further improved. In addition, the company realized a net profit attributable to shareholders of listed companies of 191,000 yuan, down 14.1% year-on-year. As of the end of the reporting period, the total assets of ST Hongsheng was 190 million yuan, down 2.4% year-on-year.

　　According to the data, Zhengzhou Deheng Hongsheng Technology Development Co., Ltd. was established in 1992, headquartered in Zhengzhou City, Henan Province, and listed on the main board of Shanghai in 1994. ST Hongsheng completed bankruptcy and reorganization in 2016, and implemented major asset restructuring. The company’s main business changed from the previous financial leasing business to its own house leasing business. In addition, during the reporting period, the company’s main business was automobile interior business.

　　According to reports, as a listed company that has been warned of delisting risks for years, ST Hongsheng has been engaged in a "shell-keeping" defensive war, and has undergone five reorganizations before and after, and its main business has changed several times. During the "shell-keeping" period, ST Hongsheng has successively sent out contact intentions with Ganzhou Rare Earth, Shanxi Natural Gas, Huawei Nigeria, OCT Technology and many other companies.

　　It was not until December 2016 that ST Hongsheng ushered in a turning point. At that time, Lhasa Zhihe, a subsidiary of Wang Wenxue, the head of Huaxia Department, transferred the total price for 900 million yuan and took over 20.87% of the shares held by Puming Logistics, the controlling shareholder of ST Hongsheng. Together with the 5% of the shares transferred by Zhang Jincheng, the former investment shareholder, for 140 million yuan, Lhasa Zhihe became the new controlling shareholder of ST Hongsheng, while Wang Wenxue paid only 1.04 billion yuan, which was called the most in its three "shell buying campaigns". It is understood that Wang Wenxue controls a huge capital territory. Apart from ST Hongsheng, he is also the actual controller of several A-share companies such as Huaxia Happiness, Yulong and Visionox.

　　According to the Securities Times, after two years in ST Hongsheng, Wang Wenxue failed to effectively revitalize this enterprise that was once on the verge of delisting, so he decided to quit, and the takeover party was the brother enterprise of Yutong Bus, another A-share company. On December 7, 2018, Lhasa Zhihe, the controlling shareholder of ST Hongsheng, signed a Share Transfer Agreement with Tibet Deheng, intending to transfer all the 41.64 million shares of ST Hongsheng to Tibet Deheng. After the transfer is completed, the controlling shareholder of the listed company will be changed to Tibet Deheng, and the actual controller will be changed to seven natural persons including Tang Yuxiang.

　　As can be seen from the stock price trend, since December 2016, the share price of ST Hongsheng has been falling all the way. By the close of December 7, 2018, the market value of all the shares of ST Hongsheng held by Lhasa Zhihe was 363 million yuan, shrinking by over 60%.

　　Finance and real estate are the most "rich"

　　The worst company can’t pay a penny.

　　What is the salary situation of A-share industry and executives in 2018? Wind data shows that from the perspective of the industry, in 2018, the average annual remuneration of financial industry executives reached 22.66 million yuan, far ahead. The real estate industry followed closely, with the average annual remuneration of executives reaching 14.275 million yuan.

　　The Zhongxin Jingwei client combed and found that according to the 19 commonly used industries classified by the CSRC, the average executive salary of 19 industries in 2018 was 7.956 million yuan, while in 2017, the average executive salary of these 19 industries was 7.302 million yuan, a year-on-year growth rate of 9%.

　　Wind data shows that from the company level, the total salary of Fangda Special Steel in 2018 is 169 million yuan. The worst is *ST Yida, whose salary showed zero last year. Behind this, *ST Yidain’s annual report was "non-standard" for two consecutive years and its listing was suspended on July 19. Not only that, this A-share "worst" company currently has only two employees, the general manager and the chief financial officer, and its revenue last year was zero. The annual salary of *ST Yangfan, which ranks second to last, is only 525,000 yuan.

　　From the perspective of specific executive compensation, Zhong Chongwu, the former chairman of Fangda Special Steel (who left office on March 6, 2018) topped the list with an annual salary of 40.351 million yuan. The salary of 11 executives in the company exceeded 10 million yuan. According to statistics, from 2008 to 2018, Zhong Chongwu and Xie Feiming, the two chairmen of Fangda Special Steel, paid a total of 228 million yuan.

　　However, in sharp contrast to the annual salary of Fangda Special Steel executives, the per capita salary of employees in the company is not high. According to China Economic Net, in 2018, the annual per capita salary of Fangda Special Steel employees was only 165,900 yuan. In this regard, Fangda Special Steel explained in the annual report that the pre-tax salary of senior managers consists of the basic salary in 2018 and the incentive salary in 2017.

　　In fact, it is nothing new for Fangda Special Steel executives to receive high salaries and pile up a "cash wall" to pay bonuses. However, it is questioned whether Fangda Special Steel excessively pursues performance and rewards, but ignores the importance of safety.

　　It is reported that in the first half of this year, eight people were killed in two accidents at Fangda Special Steel. In addition, the company’s revenue is not directly proportional to the net profit. According to the semi-annual report of 2019, Fangda Special Steel achieved an operating income of 8.253 billion yuan, an increase of 0.18% year-on-year; The net profit attributable to shareholders of listed companies was 1.055 billion yuan, a year-on-year decrease of 19.19%.

Involving five major fields of electric drive, battery, large die-casting, intelligent driving, and intelligent cockpit, Xiaomi Auto’s first press conference has several highlights

　　At the first press conference of Xiaomi Automobile, Lei Jun summed up in one sentence, "We have to do at least 100" first, only, and most ", so it is not a problem for me that friends occasionally cut off one or two Hu." The technical links of the press conference mainly involved five fields: electric drive, battery, large die casting, intelligent driving, and intelligent cockpit. Among them, the world’s highest speed motor, 9,100 tons of large die casting and other three electric and manufacturing technologies all made Xiaomi’s eyes shine in the industry for technology-based cars. In the second half of the press conference, Lei Jun also spent an hour and a half talking about SU7 design, safety, performance and other key indicators. Compared with the new car conference, the price was not announced. But Lei Jun said: "100 degrees, ternary lithium, Ningde era" three cars together are more than 400,000 yuan. So don’t shout 99,000 anymore, 149,000 is unlikely, still have to respect technology ", Lei Jun ruled out the price below 149,000.

　　motor

　　Xiaomi has released three self-developed motors, HyperEngine V6/V6s and HyperEngine V8s. The HyperEngine V6/V6s super motor has a maximum speed of 21000rpm, of which the HyperEngine V6 has a maximum power of 299PS and a maximum torque of 400N · m. The HyperEngine V6s has a maximum power of 374PS and a maximum torque of 500N · m. The HyperEngine V8s has a maximum speed of 27200rpm, an output power of 425kW and a peak torque of 635N · m. It adopts the industry’s first 960MPa highest strength special silicon steel sheet and is expected to be on the bus in 2025.

　　Battery

　　Xiaomi self-developed the world’s first CTB integrated battery with inverted cells. The battery capacity can reach up to 150 degrees, and the theoretical CLTC cruising range is as high as 1200km +. The CTB integrated battery adopts two-in-one floor cover, cell inversion, multi-functional elastic interlayer and minimalist wiring harness design, which makes the integrated efficiency reach 77.8%, the overall improvement is 24.4%, and the height of 17mm is released. The double large-sided strong cooling solution ensures that both sides of the battery have heat dissipation plates, and the cooling area reaches the largest in the same class of 7.8m 2, achieving a cooling effect of 4 times the industry average. "Challenge the king of winter trams", Lei Jun said, Xiaomi aspires to be the king of winter electric vehicle battery life. After the new car is launched, everyone is welcome to test it.

　　Large die casting　

　　Xiaomi HyperCasting, a 9100t super die-casting technology developed by Xiaomi, has become the only domestic automaker to independently develop both a "large die-casting equipment cluster" and a "die-casting material".

　　In terms of equipment innovation, the cluster equipment covers an area of 840m 2, with a total weight of 1050t, which is equivalent to the size of two basketball courts, and the clamping force reaches 9100t at the top of the industry. In terms of material research and development, the optimal alloy formula is selected from 10.16 million formulas to ensure the perfect combination of strength, toughness and stability. Self-developed high-strength, high-toughness and heat-free environmentally friendly die-casting material "Titan Alloy". Focus on the pain point of "high maintenance cost" of integrated die-casting, and adopt a three-stage repairable design: integrated die-casting rear floor + medium and high-speed collapse zone + low-speed collapse zone. In medium and low-speed collisions, there is no need to replace large die castings; in high-speed collisions, this design can meet the 90km/h rear collision mark.

　　Smart driving

　　Adaptive zoom BEV technology, road large model and super-resolution occupancy network technology constitute the three key technologies of Xiaomi’s intelligent driving. The industry’s first adaptive zoom BEV technology can zoom like the human eye, and can adaptively call different perception algorithms according to different scenes. Its perception grid can reach a minimum of 0.05m and a maximum of 0.2m, the recognition range extends from 5cm to 250m, the parking scene is more accurate, the urban scene can be seen wider, and the high-speed scene can be seen farther.

　　In terms of obstacle recognition, Xiaomi’s super-resolution occupancy network technology implementation provides unlimited types of special-shaped obstacle recognition. Compared with the traditional occupancy network, which relies on natural language models to describe obstacles as squares, Xiaomi’s innovative super-resolution vector algorithm can simulate all visible objects into three-dimensional objects with continuous surfaces, thus improving the recognition accuracy to 0.1m, which is twice the industry level. The self-developed one-button noise reduction function completely eliminates the impact of rain and snow on the recognition, greatly reducing the probability of false recognition. On the hardware side, the system is equipped with top-of-the-line configuration, including two NVIDIA Orin high-computing power chips, with a comprehensive computing power of up to 508TOPS. The sensing hardware includes 1 lidar, 11 high definition cameras, 3 millimeter wave radars and 12 ultrasonic radars (Max version models). Lei Jun stressed that the goal of Xiaomi Smart Driving is to enter the first echelon of the industry in 2024, and it is expected that the city NOA will land in 100 cities in 2024. The longer-term goal is to be the first in the industry.

　　Smart Cockpit

　　The smart cockpit is Xiaomi’s "comfort zone", and it is the last part of Xiaomi’s "people, cars, and home ecology". In addition to the basic driver interconnection function, there is also a rich car and machine ecology. The first five-seat five-tone zone interaction function supports stable and cooperative wake-up of multiple devices. Almost all operations can be completed through the voice control of "Xiao Ai Classmate", and the core functions support offline use. The car start-up speed reaches 1.49 seconds. The industry’s first cockpit system streaming OTA upgrade technology realizes the upgrade while downloading. Mijia devices have no feeling of getting on the bus. At present, Xiaomi’s smart cockpit has supported 1000 + Mijia devices, automatic discovery, password-free access, and can set up automated scenes. Xiaomi also opens a unified standardized interface and rich standard protocols, and the built-in CarIoT expansion base supports a variety of devices to access, such as smart fragrances. Four sets of Pin point power supply communication design expandable physical buttons. In addition to Xiaomi users, "Apple users can also have a silky experience", Xiaomi fully supports wireless CarPlay car, and provides iPad-exclusive accessories and exclusive applications on the rear expansion screen.

　　In 1003 days, Xiaomi Auto finally ushered in its first official release. "3,400 engineers, over 10 billion R & D investment, more than 10 times the investment". Xiaomi handed in its first answer sheet at the end of 2023 when it rolled up to Flying. From Wei Xiaoli in the car 2.0 era to "Hua Xiaomei" in the 3.0 era, building a car has never been an easy task. As a contrast, NIO delivered ES8 for the first time in June 2018. Its 2016-2018 R & D expenses for three consecutive years were 14.65, 26.03, and 3.998 billion yuan respectively, with a cumulative total of 8.066 billion yuan. As of the end of 2018, there were 808 employees worldwide. It can be seen that in terms of funds, the scale of tens of billions is basically the basic investment of a new enterprise, but in terms of team size, Xiaomi has indeed expanded rapidly. Therefore, Lei Jun also repeatedly "warned" the price of SU 7, lowering users’ price expectations.

　　In addition to the previous "may be a bit expensive", at the press conference, when introducing the SU 7’s zero-hundred acceleration, maximum speed and maximum power compared with Taycan Turbo and Model S, Lei Jun once again sounded the "price alarm", "Speaking of this, I believe everyone has a basic understanding of what kind of car SU7 is, so everyone really don’t call it 99,000, this is impossible, 149,000 is also unlikely." At present, in the car industry where prices are flying, Lei Jun obviously does not want to take the "cost-effective" route. After this technical conference, Xiaomi’s technology can support the high price of SU 7, depending on the market feedback. (Source: Xiaomi Auto)
