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