Abstract
A spark arrestor aspirating muffler for an internal combustion engine which comprises an outer body or housing having an exhaust gas inlet in one end and a gas outlet in the opposite end. Located immediately upstream of the outlet is a venturi and air is drawn into the throat of the venturi through an air inlet tube connected to a pre-cleaner for the engine. A baffle plate containing a series of louvered openings is positioned upstream of the venturi and the exhaust gases entering the gas inlet conduit are swirled outwardly as they pass through the louvered openings and are discharged through the venturi. The solid particles in the swirling exhaust gas are thrown outwardly and move along the inner surface of a tubular member which is secured to the downstream side of the baffle and are collected in a collection chamber.
