What are the reasons for the high fuel consumption of China V diesel vehicles?

China V diesel vehicles have high fuel consumption for the following reasons: Low tire pressure: If the tire pressure is lower than the standard pressure, the contact area and rolling resistance of the tires will increase, not only causing continuous wear on the shoulders of the tires but also leading to a sudden increase in fuel consumption. Therefore, regularly checking tire conditions not only ensures driving safety but also helps save fuel. TPMS is the Tire Pressure Monitoring and Testing System. The TPMS uses radio waves and sensing technology to monitor tire pressure levels. The TPMS indicator light turning on indicates that one or more tires are underinflated or overinflated. Engine carbon deposits: After carbon deposits form in the engine, the injected fuel will first be absorbed by the carbon deposits in the intake port and not fully enter the engine. Of course, this fuel will be released after the engine heats up, enriching the air-fuel mixture, but it will not deliver more power to the engine, leading to increased fuel consumption. Poor fuel quality: The quality of the fuel is also related to fuel consumption. If low-quality fuel is used, it will result in incomplete combustion and failure to fully release the intended power. To obtain sufficient power, the accelerator must be pressed deeply, naturally increasing fuel consumption.

Having driven a China V diesel vehicle for some years, high fuel consumption is most commonly caused by aggressive driving habits, such as frequent sudden acceleration and braking, which can drastically increase engine fuel usage. Vehicle load also plays a role—if you often carry heavy cargo or tow trailers, the added weight naturally leads to higher fuel consumption. Poor maintenance is another issue; for example, a clogged air filter makes it harder for the engine to breathe, requiring extra fuel, while underinflated tires increase rolling resistance and raise fuel consumption. The China V diesel vehicle's unique DPF (Diesel Particulate Filter) is prone to clogging, and once the regeneration mode is triggered, the system burns extra fuel to clean it, causing a significant spike in fuel consumption. It's advisable to drive smoothly, regularly check filters and tire pressure, and occasionally drive on highways to assist DPF self-cleaning. Neglecting these small details long-term will only cost you more.

What to Do When the Car Indicates High Transmission Temperature?

When the car indicates high transmission temperature, you should stop driving and turn off the engine. Continuing to drive can easily lead to serious transmission failures. There are many reasons for excessively high transmission temperature, such as damage to the transmission oil cooler or prolonged non-replacement of transmission oil. Using a circulation machine for oil change can remove over 90% of the old transmission oil, making this method cleaner and more thorough. When purchasing transmission oil, choosing the original product is sufficient. Original transmission oil has been tested by the car manufacturer, ensuring it meets the transmission's requirements under various operating conditions.

Does Transmission Oil Leak Affect Usage?

Transmission oil leakage affects usage and the normal operation of the vehicle. If an automatic transmission oil leak is not addressed promptly, the car may experience reduced power. Symptoms of transmission oil leakage include weak acceleration, impact sensations in low gears, inability to increase power while driving, and slipping of the transmission. In severe cases, low oil levels due to leakage can cause abnormal noises during transmission operation. The primary cause of transmission oil leaks is the aging of sealing components. Prolonged use of the vehicle leads to the aging of sealing parts, which can shrink, harden, and even break under high-intensity working conditions.

Can You Continue Driving with a Faulty Transmission Valve Body?

You should not continue driving if the transmission valve body has issues. A malfunctioning transmission valve body can cause sticking phenomena. If leakage occurs, it may lead to gear shift shocks during transmission operation, significantly reducing shifting efficiency and causing a decline in the vehicle's power output. The transmission valve body is a hydraulic control unit where spools move laterally to alter hydraulic fluid direction and pressure during transmission operation, enabling automatic gear shifts. Valve body failures are more common in automatic transmissions, which were developed as an alternative to manual transmissions. Vehicles equipped with automatic transmissions shift gears automatically based on driving speed and engine RPM.

Why Did Audi Abandon Torsen?

Here are the reasons why Audi abandoned Torsen: Compromise on patent barriers: Torsen's patents are held by a steering system manufacturer called JTEKT. The lack of patent technology is also a reason why Audi abandoned Torsen. Compromise on emission regulations: Torsen, including the crown gear differential, is indeed unfriendly to fuel economy, mainly due to transmission efficiency and weight, which is another reason why Audi abandoned Torsen. Confidence in its own technology: With significant advancements in sensor technology and electronic control technology, Audi has the courage to boldly experiment and develop new technologies.
