Who I am ---------- Disclaimer Automotive glossary Throttle Valve | Definition Throttle Valve: The throttle valve is located in the suction part between the air filter and the intake manifold of the engine. Either in the carburetor or, with injection engines, in its own throttle valve case. Its task is to control the in each case required engine power, through the amount of air streaming in, by releasing the airflow more or less. With older models it is moved by wire directly from the gas pedal. With more modern vehicles it is controlled electrically, also depending on the gas pedal position.![]() All definitions |
