Beschreibung
Zusammenfassung:	An arrangement for reducing noise produced by an engine idle air bypass valve and passage includes positioning an acoustic diverter at the end of the air bypass passage to force the noise away from exterior surfaces of a downstream chamber and toward the internal cavities of the engine such as a cylinder head. The diverter of the present invention reduces noise without causing restriction of air flow through the air bypass passage.
