What is the function of automobile throttle?

Throttle has many functions, mainly in the following aspects: 1, to improve power by accelerating or decelerating; 2, through its self-regulation, correct the air intake function; 4. The function of controlling the operation of the engine assembly (the idle switch inside the engine is working); 5, control the flap, through the work of the sensor, control the size of the air intake, in order to facilitate the promotion of power. Dirty throttle is mostly caused by poor air quality and poor oil quality. Due to the negative pressure, the carbon deposit produced in the process of gasoline combustion will infect the throttle valve and make it not close well, thus increasing the intake air, causing signal transmission errors, resulting in high fuel consumption and engine idling jitter. Therefore, during the maintenance period, always check the throttle opening. If it exceeds the normal range, it should be cleaned.
