Where is the accelerator in the car?

The throttle valve is located at the engine intake of the vehicle, behind the engine air filter and in front of the intake manifold. Throttle is called the throat of an automobile engine. Because the throttle valve is connected with the air filter and the engine block, the main function of the throttle valve is to control the intake air, which will affect the fuel injection. As the intake air increases, the fuel injection will also increase, so the throttle valve is a device to control the intake air and fuel injection into the cylinder. There are two kinds of throttle: traditional cable throttle and electronic throttle. Now there are more and more models, all of which use electronic throttles. Electronic throttle can control the throttle opening more accurately, and then it can be better controlled in environmental protection and fuel economy.
