ABSTRACT:
An air intake silencer for an internal combustion engine of the two-stroke cycle type, for example a snowmobile engine, comprising a housing for connection to the intake side of the engine carburetor, and a filter chamber and resonance chamber defined within the housing to filter out engine noise in high and low frequency ranges. An intake duct of smooth uninterrupted tubular configuration extends in an axial direction through the housing and has a perforate tube section through which the incoming air is smoothly distributed to the filter chamber. The resonance chamber is separated from the filter chamber by means of a perforated baffle plate, the dimensions and volume of the chambers being selected to correspond to the frequency ranges of the noises to be eliminated.
