Fresh gas supply device for IC engines has fresh gas distributor connected to by-pass resonator or Helmholtz resonator to intensify combustion chamber resonance charge

摘要

The device has a fresh gas distributor (4), connected to a fresh gas feed (5) and to an IC engine (1). The distributor is also connected to a resonator (9), e.g. a by-pass resonator or Helholtz resonator. This intensifies a resonance charge of the combustion chambers (2) when at least a pre-set RPM or RPM range of the engine is present. The resonator volume communicates with the fresh gas distributor, and is adjusted by an adjusting device dependent upon RPM. The connection is opened/closed RPM dependent by a control unit (15).
