What are the benefits of throttle cleaning?

4S stores always recommend cleaning the throttle, which is usually unnecessary because the throttle has not been cleaned. So what are the benefits of throttle cleaning?

The advantages of cleaning the throttle valve are: smooth intake, recovery of idle speed and emission of the car, and recovery of the power of the car.

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It is called the throat of an automobile engine, and it can also control the amount of air entering the engine.

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 controls the opening of the throttle according to the air intake required by the engine through the throttle position sensor, so as to adjust the opening of the throttle.
