What is the reason why the accelerator can't lift the speed?

1. When stepping on the accelerator, the cable will drive the accelerator, that is, the accelerator. There is a position sensor on the throttle. The control unit knows the throttle opening according to the signal of the throttle position sensor, then calculates the corresponding signal voltage, and finally calculates the fuel injection quantity of the vehicle according to this signal voltage. Therefore, if the throttle position sensor is too dirty or the voltage is unbalanced, the electronic throttle will fail and the speed of the throttle will not go up.

2. After troubleshooting the electronic throttle, we turned our attention to the three systems of the engine, namely air intake, oil circuit and ignition. In fact, the throttle position sensor signal is a member of the intake system, and the normal operation of the engine needs sufficient air. The air intake system leaks or is blocked, the power drops, the speed can't go up, and the car body shakes when refueling.

3. The oil system of the engine is also very important. If inferior gasoline is added, it is likely to lead to gasoline pump burning, three-way catalytic failure, piston failure and so on. , directly affect the engine power, and easily lead to engine flameout and acceleration.

Extended data:

A device for controlling the fuel supply of an internal combustion engine. The accelerator pedal is also called the accelerator pedal. It is a part of automobile fuel supply system. By controlling the amount of pedaling, the throttle opening of the engine, the air intake and the oil quantity through the computer, the engine speed can be controlled.

When starting the engine, don't step on the accelerator pedal to the end, just slightly higher than the idle accelerator. When starting, it is best to refuel just before the clutch linkage point, and the throttle opening should be medium or small. Loosening the clutch should be closely coordinated with stepping on the accelerator, and the action should be agile.
