THROTTLE BODY. The throttle body is an important component of the internal combustion engine intake system and is designed to regulate the amount of air entering the engine. By changing the position of the throttle plate, the engine management system controls airflow into the intake manifold, which directly affects the formation of the air‑fuel mixture and engine power output. In modern vehicles the throttle body may use either mechanical or electronic control (electronic throttle or “drive‑by‑wire” system). Electronic throttle bodies include an actuator and position sensors that transmit information to the engine control unit for precise engine operation management. The assembly typically consists of the throttle housing, rotating throttle plate, drive mechanism and throttle position sensors. Malfunctions of the throttle body can lead to unstable engine operation, reduced power, increased fuel consumption and diagnostic errors in the engine control system. The catalog includes throttle bodies and intake system components for various passenger cars, SUVs and commercial vehicles. Selection is based on vehicle model, engine type and engine management system specifications.
