What is the reason for the high fuel consumption in Qi Jun?

The main reasons for the high fuel consumption in Qi Jun are: 1, and the added fuel quality is too low. If the fuel quality added to the car is too low, the fuel and mixture can not be fully burned in the engine, which will lead to the waste of some fuel and affect the fuel consumption of the car. Therefore, it is necessary to add high-quality fuel to reduce fuel consumption. 2. Violent driving: If the driver drives the car too violently, the engine speed is often high, which leads to the overload and easy rotation of the car engine, thus increasing the fuel consumption of the car. It is suggested to change the driving mode, learn to drive lightly, brake early and start slowly. 3. Too much carbon deposit in the engine: The carbon deposit in the engine is too serious, which leads to the failure of normal fuel delivery, and the car has symptoms of increased fuel consumption and reduced power. At this time, the engine carbon deposit must be removed immediately. 4. Excessive vehicle weight: Excessive vehicle weight will increase the engine load, which in turn will increase fuel consumption. Therefore, the self-weight of the car must be reduced.
