What is the function of automobile throttle?

The throttle valve is the throat of the automobile engine, which controls the air intake of the automobile engine, and then the driving computer judges the fuel injection quantity according to the value of the air flow sensor. Therefore, the accuracy of throttle intake is related to the fuel injection quantity. It is the premise of stable operation of automobile engine. So the accelerator pedal we step on actually controls not the accelerator, but the opening of the accelerator.

The air in the engine needs to pass through our throttle, which is very easy to accumulate dust. When there is too much dust, the air entering our throttle will be blocked by dust at the same opening, so less air will actually enter the engine at the same opening. Therefore, in this case, we need to clean our throttle to ensure that our throttle can accurately enter the air volume in the engine.
