Where is the Peugeot 408 throttle?

The throttle valve of an automobile is located behind the air filter element of the air intake system and in front of the air intake manifold.

The following is a detailed introduction about the throttle:

1. Throttle is the throat of the engine, which can control the air intake of the engine. When the driver presses the accelerator pedal, he actually controls the throttle opening instead of directly controlling the fuel injection quantity.

2. Throttle is a controllable valve to control air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It is connected to the air cleaner at the top and to the engine block at the bottom.
