摘要： A muffler with a housing for receiving exhaust gasses from an engine is disclosed. The muffler includes a housing with an inlet and an exit, a baffle plate partitioning the housing into first and second chambers. The baffle plate includes a catalyst receptacle in the first chamber, the second chamber includes the exit of the housing. A catalytic converter element with a longitudinal axis is housed within the catalyst receptacle, the catalytic converter element is positioned within the catalyst receptacle such that exhaust gas passes through the catalytic converter element in a direction transverse to the longitudinal axis of the catalytic converter element and through the second chamber to exit the housing.

摘要： A breather system for an engine used to vent combustion, or blow-by, gases. The breather system has an axial breather passage disposed within a camshaft of the engine. A radial opening is in fluid communication with the axial breather passage. A valve is positioned within the radial opening in order to prevent oil from entering the axial breather passage when the engine is not in operation.
