ABSTRACT:
Two embodiments of induction systems for internal combustion engines that improve charging efficiency, particularly at low speeds and throttle openings. In each embodiment a plenum chamber is provided that communicates with the induction system between the throttle valve and the chamber which is served. In each embodiment a control valve controls the communication of the plenum chamber with the induction passage for substantially restricting the communication when the throttle valve of the engine is in its wide open position.
