throttlebody

A throttle body is a component in internal combustion engines that controls the amount of air entering the engine. It is typically located between the air filter and the intake manifold. The throttle body consists of a butterfly valve that opens and closes to regulate the airflow. When the accelerator pedal is pressed, the throttle body opens, allowing more air into the engine and increasing the engine's power output. Conversely, when the pedal is released, the throttle body closes, reducing airflow and decelerating the engine. The throttle body is a crucial part of the engine's air-fuel mixture control system, working in conjunction with the fuel injectors to ensure proper combustion. It is also equipped with an idle control mechanism to maintain the engine's idle speed. The throttle body's design and functionality can vary depending on the engine type and manufacturer.
