Where is the throttle of the truck?

The truck throttle is located behind the air filter element of the air intake system and in front of the air intake manifold. The throttle is the throat of the engine. Throttle can control the air intake of the engine. When the driver presses the accelerator pedal, he actually controls the throttle opening, not the fuel injection quantity directly. Extended data:

Reason why the crankcase ventilation pipe is connected to the throttle valve: 1, environmental protection requirements. 2. The gas extracted from the crankcase by the negative pressure of intake air becomes cold when it reaches the intake pipe, and the oil in it will condense on the intake port and the throttle valve, and then the carbon deposit in the steam will also be deposited on these parts, because the air flow in the gap where the throttle valve is opened is the largest, the space is small, and the gas temperature is low, so this part is the easiest to condense.
