Throttle in the intake pipe, add a butterfly valve, valve rotation using different openings of different ways to control the gas flow, to further control the engine power. Now the design vehicle to use more electronic throttle, the engine control module can be accurately controlled so that the output increase, decrease fuel consumption.

Fresh air from the inlet, engine air filter all the way to move forward, the next encounter is the throttle, which is commonly known as the "throttle." This is the engine, the only controlled by the driver's body in carburetor engines, as this task by the carburetor; in jet engine oil, replace the carburetor throttle body. The introduction of a jet fuel supply system, fuel gas directly into the front of the injection by the jet, throttle body, less fuel and air mixture to the task. However, in order to accurately control the fuel mixture, than the carburetor throttle valve body is not easy.

A typical throttle body (throttle body), should have the main inlet and throttle, and throttle are controlled by a spring, when the driver depresses the accelerator is not when the throttle is turned off, so most of the air be excluded from the valve outside; and depress the accelerator pedal when driving, the throttle cable will pull the throttle spring, the valve opens to allow air into the engine from the main inlet. In addition, there is a throttle sensor to the throttle opening into electronic signals, making the engine supervisory system (ECU) to control the fuel injection based on this amount.

There is also a throttle body idle speed control valve is controlled by the step into the motor, the engine ECU in the cold, open and close air-conditioning, neutral and D file conversion and other timing and control idle speed motor actuator to adjust the engine idle speed of the right into the air.

The traditional mining throttle cable throttle is mechanically driven, but to the integrity of the entire vehicle control, and many new models have adopted electronically controlled throttle.

In addition, there is a throttle sensor to the throttle opening into electronic signals, making the engine supervisory system (ECU) can be based on throttle opening to control the fuel injection quantity.
