There are several types of throttle bodies.

Throttle body mainly includes traditional cable-type and electronic throttle. The traditional engine throttle control mechanism works through a cable (soft steel wire) or a pull rod. One end of this cable is connected to the accelerator pedal, and the other end is connected to 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. The function of the throttle is as follows: 1. Automobile throttle is a controllable valve, which is used to control the air entering the engine. After entering the intake pipe, it will be mixed with gasoline (different models and different designs) to become combustible mixture, which will participate in combustion and do work. One of the steps of providing power for the vehicle; 2. Throttle is the most important component in EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine body, which is the throat of the automobile engine and controls the speed; 3. Whether the car accelerates flexibly is closely related to the cleanliness of the throttle. By stepping on the accelerator, the owner controls the opening of the accelerator to achieve the purpose of slowing down.
