Where is the engine throttle position?

The throttle of an automobile is generally at the engine air intake, behind the engine air filter and in front of the intake manifold. The following is a detailed introduction about the automobile throttle: 1. Throttle is a controllable valve that controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion will be successful. It is connected with the air filter at the top and the engine block at the bottom, and is called the throat of the automobile engine; 2. The accelerator pedal actually does not control how much gasoline is injected, but controls the opening of the throttle to increase the air intake, so that when the air intake increases, the fuel injection will also increase.
