Structure of throttle valve

The throttle body is mainly composed of throttle and integral idle stabilizer.

Function of throttle valve

Throttle (also called throttle body) is familiar to everyone. Because the throttle is dirty, it should be cleaned frequently to solve jitter and fuel consumption. Throttle has many functions, mainly in several aspects:

1, improve the power by accelerating or decelerating;

2, through its self-regulation, correct the air intake function;

3. Why can't the spark plug of the EFI car get water under normal circumstances? Because when the throttle valve is opened to the maximum extent, the nozzle will stop injecting oil and play the role of cleaning the cylinder;

4. The function of controlling the operation of the engine assembly (the idle switch inside the engine is working);

5, control the flap, through the work of the sensor, control the size of the air intake, for the promotion of power;

Dirty throttle is mostly caused by poor air quality and poor oil quality. Due to the negative pressure, the carbon deposit produced in the process of gasoline combustion will infect the throttle valve and make it not close well, thus increasing the intake air, causing signal transmission errors, resulting in high fuel consumption and engine idling jitter.
