What is the reason for the fault light turning on when braking in the Weizhi v2?

What is the difference between W12 and V12?

Here are the differences between W12 and V12: 1. The advantages of V-type engines are: stable operation (for V6, V8, V12), space-saving. The disadvantages are: relatively complex structure, which is not conducive to maintenance and repair, and the cost is higher. At the same time, V3, V5, including V10, are not very stable due to their structure or displacement, especially the V10-3L engine used as an F1 engine, which requires a lot of effort and funding to ensure its stability. 2. The W-type engine is a type of V-type engine, but it divides the cylinders on both sides of the V-type engine into two groups. Viewed from the side, it looks like a "W", hence the name. The W12 engine is composed of two V6 engines. Its biggest advantage is its compact structure, easy arrangement, and optimization of the engine compartment space. The disadvantage is that the structure is too complex. The W-type engine is a patented technology of Volkswagen. Only Volkswagen and its brands use W-type engines. Currently, there are mainly W12 and W16. The W12 is smaller in size than the V12.

Is the car windshield film applied on the inside or outside?

Car window film should be applied to the inside of the car glass. Applying it on the inside protects it from wind and rain, slowing down the aging process and extending its service life. Additionally, the film won't be subjected to significant external interference during use, avoiding scratches or damage. Since it's not exposed to the elements, the adhesion remains stronger, preventing issues like peeling corners. Below are 7 major benefits of car window film: 1. Heat insulation and sun protection. The film effectively blocks a large amount of heat generated by infrared rays. 2. UV protection. Medium and long waves of ultraviolet rays can penetrate thick glass, but applying heat-insulating film can block most UV rays, preventing skin damage and reducing the aging of car interiors. 3. Safety and explosion-proof. The base layer of the film is made of polyester, which is highly resistant to tearing and puncture. Combined with the adhesive layer, the film enhances the glass's strength, preventing injuries caused by accidental glass breakage to drivers and passengers. 4. Creating a private space. By choosing the right type of film, the interior of the car becomes less visible from the outside while maintaining clear visibility from the inside, ensuring privacy and safety. 5. Reducing air conditioning consumption. Heat-insulating film compensates for the loss of air conditioning cooling capacity, quickly lowering the interior temperature and saving fuel to some extent. 6. Enhancing aesthetics. According to personal preferences, applying film can personalize and beautify the car. 7. Anti-glare. It reduces accidents caused by glare factors.

How Many Kilometers Should the Transmission Oil of a Small Car Be Changed?

Automobile transmission oil is generally changed every 40,000 kilometers, which is what people often refer to as gear oil. Transmission oil plays a crucial role in ensuring the normal operation of the transmission and extending its lifespan. The DEXRON standard by General Motors and the MERCON standard by Ford are among the most representative standards, which specify the performance indicators of transmission oil. Additional information: 1. Automatic transmission fluid (ATF) cannot be completely drained using atmospheric pressure, as this method only removes about half of the used oil. The remaining fluid, along with sludge and impurities, can accumulate in the valve body, torque converter, and cooling lines, leading to blockages in the system's internal oil passages. 2. Over 99% of automatic transmission failures are caused by overheating and prolonged use of ATF without replacement, leading to the accumulation of impurities. It is also important to check whether the transmission pan is deformed or if there are any leaks in the transmission lines. 3. Automatic Transmission Fluid (ATF) is specifically designed for use in automatic transmissions. Early automatic transmissions did not have dedicated fluid and instead used engine oil. Due to significant differences in operating conditions and technical requirements, the practice of using engine oil as ATF was quickly abandoned. 4. Today's dedicated automatic transmission fluids serve as the hydraulic fluid for the torque converter, the lubricating oil for the planetary gear structure, and the hydraulic oil for the shifting mechanism.

Why does the engine shake when stationary in D gear?

Reasons for car shaking when stationary in D gear: When the car is in D gear with the brake pedal pressed, the transmission fluid inside the torque converter flows at high speed and is subjected to significant shear force. If this condition persists for too long, the temperature of the transmission fluid will rise. The engine will inject more fuel due to increased load, leading to higher fuel consumption and an increase in engine temperature. Therefore, keeping the car in D gear with the brake pressed for extended periods is particularly detrimental to both the engine and transmission. Generally, the reasons for an automatic transmission car shaking in D gear are as follows: 1. Engine or transmission mounts, commonly known as engine mounts, may be affected due to aging or improper installation. Further inspection is needed to determine if replacement is required. 2. Gear engagement shock in the transmission, caused by impurities or contamination in the transmission fluid, leading to poor performance of the transmission hydraulic system. Further inspection of the transmission fluid and components is necessary. 3. Severe contamination of the engine throttle body, causing changes in engine load, which in turn affects the normal operation of the transmission. 4. Improper engine air-fuel mixture, such as poor engine performance, issues with spark plugs, fuel injectors, etc. Further inspection is needed to confirm the cause of the fault.

What Causes the Decrease in Coolant?

It is normal for coolant to have some minor consumption, as although the entire cooling system is sealed, the coolant reservoir cap has a pressure relief hole. Methods to determine if coolant is insufficient: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to a lack of coolant, though it could also be caused by excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add coolant. Inspect the water level markings on the coolant reservoir. The normal coolant level should be between the maximum and minimum marks. To determine if coolant is lacking, check the markings—if the coolant is below the minimum level, it indicates a deficiency. Precautions for replacing coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leaks or cracks in the pipes, with particular attention to the five-way hose. The five-way hose is named for its five connections to various parts, and coolant flows through it before being distributed to different sections of the car to perform its function. If there are signs of coolant leakage in this area, replace the hose or resecure the connections as needed.

Where Does the Airbag Deploy From?

Airbags typically deploy from the center of the steering wheel. The steering wheel may appear smooth and seamless, but the plastic in the "tear seam area" is very thin—usually only 0.5 millimeters thick. This area serves as the "weak zone" of the cover. In the event of an accident, when the airbag is triggered, it will deploy from this "weak zone." The working principle of airbags is as follows: 1. When a collision occurs while the vehicle is in motion, the airbag sensor first receives the impact signal. If the impact reaches the specified intensity, the sensor activates and sends a signal to the electronic control unit (ECU). 2. Upon receiving the signal, the ECU compares it with its stored data. If the conditions for airbag deployment are met, the drive circuit sends an activation signal to the gas generator in the airbag module. 3. The gas generator ignites the propellant upon receiving the signal, producing a large volume of gas. This gas is filtered and cooled before entering the airbag, causing it to rapidly inflate and break through the padding in a fraction of a second. The airbag forms an elastic cushion in front of the driver or passenger, then promptly deflates and contracts to absorb the impact energy. This effectively protects the head and chest, preventing or reducing the severity of injuries.
