The function of adding throttle in Pacific Auto Network is to accurately control the throttle opening and change the area of intake passage, so as to control the intake volume and engine working conditions. The throttle body is such a device, which is very important to the engine.

What is the function of throttle body? The throttle body is installed on the intake pipe between the air flow meter and the engine, and its function is similar to that in the carburetor. The throttle valve is linked with the driver's accelerator pedal to control the opening of the throttle valve and change the area of the intake passage, so as to achieve the purpose of controlling the intake volume and engine working conditions. The throttle body is such a device, which is very important to the engine.

Besides the main channel, there is a bypass channel on the throttle body, and the bypass channel is provided with an idle speed adjusting screw and an idle speed control valve.

The throttle body of modern electronically controlled gasoline injection engine is equipped with idle air regulator, idle auxiliary air valve, throttle position sensor and throttle buffer for assistance.

The throttle body is often used in vehicles. Generally, the function of mechanical throttle body is the same as that of electronic throttle body, but its opening is not controlled by ECU signal, but by the cable connected with the accelerator pedal, that is to say, the position of the pedal is directly related to the rotating shaft of the door panel on the throttle body, which is worth noting.
