What is the reason why the car can't step on the accelerator?

I believe that many car owners have encountered the experience that the throttle speed can't go up. That feeling seems impossible, but what's going on? Next, let's analyze the reason why the car can't speed up.

First, there is a high probability that the throttle speed of the car will not go up and the clutch will slip. 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 reason of clutch slipping is 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.

Of course, if the speed of the gas door can't go up, we should also focus on 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, the engine system should also be checked as a key point when the car refueling can't speed up.

First of all, we can do some simple checks ourselves, such as whether we have added the wrong oil. This is also possible, because adding low-grade gasoline may lead to weak acceleration, which will lead to a decline in engine power and an increase in fuel consumption.

Then there is the 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.

Then there is the intake system of the engine. 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.

The ignition system cannot be ignored. If the spark plug is poorly ignited, dripped or atomized, it will also affect the engine acceleration.

In addition, we can judge where the problem lies according to the symptoms accompanying the car, such as smoke from the exhaust pipe. If there is black smoke, there is something wrong with the combustion chamber, ignition system and valve. If the exhaust pipe emits blue smoke, then it may be that the engine oil ran to the combustion chamber, which is what we call burning engine oil.

Many people don't think this is a trivial matter, but if we don't pay attention to trivial matters, it will lead to great disaster, so the owner must go to a professional repair shop or 4S shop for repair in time after symptoms appear.
