Abstract
A self-adjusting resonator for an engine includes a housing and a working chamber. The working chamber is defined by the housing for attenuating sound produced by the engine. The working chamber is automatically variable from a first volume to a second volume in response to a negative pressure generated by air flow requirements of the engine. The first volume is greater than the second volume. The resonator is operable to tune out multiple tuning frequencies produced by the engine at various engine RPM ranges.
