There are several types of automobile throttle bodies.

There are two kinds of throttle: traditional cable throttle and electronic throttle.

1, the traditional engine throttle control mechanism works through a cable (soft steel wire) or a pull rod, one end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate.

2. 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 air intake.

Throttle is one of the most important components in EFI automobile engine system. Its upper part is the air cleaner grille, and the lower part is the engine body, which is the throat of the automobile engine. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle.

Reasons for frequent cleaning of throttle valve:

1, because the EFI engine is running, a small part of the exhaust gas generated by in-cylinder combustion will generate carbon deposit at the throttle body through the intake valve and intake pipe.

2. After the air passes through the air filter, impurities will remain in the throttle.

3. When the car is used for a long time, it will form dirt on the throttle body, which will lead to disobedience of the low-speed throttle and difficulty in starting the cold car.
