What are the faults of the automobile throttle?

You want to know "what are the accelerator faults of the car?" The relevant contents are as follows:

The faults of automobile throttle include: the vehicle can't start, or the throttle doesn't return to normal after starting; Vehicles emit black smoke and consume a lot of fuel; Vehicle idling at high speed, uneven acceleration. The function of the throttle is to control the intake flow of the engine and the air entering the engine. It is a controllable valve that determines the working condition of the engine. After air enters the intake pipe, it is mixed with gasoline to form combustible mixture, which participates in combustion and does work. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic. There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable or pull rod. One end of the cable or pull rod is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.
