Throttle valve is a controllable valve that controls the entry of air into the engine. After the gas enters the intake pipe, it will be mixed with gasoline to become a combustible mixture, which will burn to form work. It is connected to the air filter and the engine block, which is called the throat of a car engine.
Throttle four-stroke gasoline engines are generally like this. Throttle valve is one of the most important parts of today’s EFI engine system. Its upper part is the air filter air grid, and the lower part is the engine block, which is the throat of the automobile engine. Whether the car accelerates flexibly has a lot to do with the dirty dirt on the throttle. Clean the throttle can reduce fuel consumption and make the engine more flexible and powerful.
The composition of the electric throttle valve can be roughly divided into the following parts: throttle valve, electromagnetic driver, potentiometer, controller (some without, directly controlled by ecu), bypass valve.
There are two types of throttles: traditional cable-type and electronic throttle. The traditional engine throttle control mechanism works through a cable (soft steel wire) or tie rod. Electronic throttle mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, thereby adjusting the amount of intake air.
