20 12 imported guides refuel but don't drive.

I feel that the car is boring, and I don't speed up because the spark plug is damaged and the oil circuit is blocked. The best way to fill the throttle: a steady and slow throttle. When you need gas urgently, you have to step on the accelerator quickly to achieve the best speed-up effect.

The specific reasons for feeling stuffy and not accelerating when stepping on the accelerator are as follows:

1, clutch slipping

Clutch slip is mainly manifested in the acceleration of the car, the speed of the car can not be improved with the increase of engine speed, and the power of the engine can not be completely transmitted to the driving wheels, resulting in driving weakness, especially when going uphill.

The main reasons for clutch slip are: insufficient friction of clutch friction plate; Clutch is not in place, catching or disengaging; Long-term semi-clutch sports car, stepping on the clutch to slide; Shift or shift is not in place. When shifting gears or shifting gears is not fully in place, the accelerator pedal is slammed, resulting in abnormal wear of the clutch plate.

2. About the engine.

The power source is the combustion of fuel, and the engine is responsible for providing fuel and converting chemical energy into mechanical energy. Therefore, when the car can't speed up the refueling, the engine system should also be the key inspection.

First of all, you can check whether you have added the wrong oil, because adding low-grade gasoline may lead to weak acceleration, resulting in a decline in engine power and an increase in fuel consumption.

3. Engine oil system

Needless to say, the importance of engine oil can fully lubricate, reduce vibration and improve the smoothness of engine operation. If the engine oil is insufficient for a long time and the power is insufficient, the fuel consumption will increase; In the worst case, the piston hits its door, causing mechanical damage to the relevant connector. In addition, the failure of gasoline pump and the blockage of fuel filter will also lead to the decrease of engine power.

4. Engine air intake system

The engine needs air as well as oil. If the air filter, throttle and other parts are blocked or have problems, resulting in insufficient air intake, it will also cause the car to accelerate slowly and feel frustrated.
