What is the reason why modern leaders have no strength to step on the accelerator and brake heavily?

The specific reasons why cars are boring and don't accelerate 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

Besides oil, the engine needs air. 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.

Reason for heavy braking: 1, insufficient power provided by vacuum booster.

This failure may be the failure of the booster itself, or the pipeline of the vacuum booster is damaged, resulting in vacuum leakage and insufficient booster. In addition, the engine is not easy to use, resulting in insufficient vacuum and poor power-assisted effect.

2, brake booster pump failure

Engine plays a key role in the work of brake booster pump. However, due to the small displacement vehicle type, the engine power is not enough. Coupled with the hot weather and air conditioning in the car, when the owner repeatedly stepped on the brakes, the engine failed to take care of the brake booster pump, which led to the failure of the brake booster pump.

3. There is air in the brake oil circuit.

The air in the pipeline is compressed. If it is all brake oil, it will not be compressed. When there is air, the braking becomes soft, so that the braking force of the master brake cylinder on the brake cylinder will be small, and the friction between the brake pad and the brake disc will also be reduced, so that the braking distance will be longer, and a rear-end collision or collision accident may occur.

Extended data:

The throttle of the car is on the right and the brake is on the left. Except for automatic transmission, manual transmission is controlled by the left foot, and the right foot informs and controls the brake pedal and accelerator pedal, and the positions are specified.

The brake pedal is always one size larger than the accelerator.

Manual transmission models always have three pedals, namely, clutch pedal, brake pedal and accelerator pedal from left to right. You can only step on the clutch pedal with your left foot when shifting the manual transmission vehicle. Usually when driving, their left foot can't be placed on the pedal, and the brake throttle is controlled by their right foot.

There are two reasons why you can't put your left foot on the pedal for a long time. One reason is that it will lead to foot fatigue, so it is easy to brake suddenly or accelerate.
