Abstract

Small engines, e.g. of hand-held chain saws, have a muffler with a catalytic converter (1) composed of a muffler housing (2) and a lid (3) sealing the housing, and a catalytic converter element (4) mounted in the liquid, with an exhaust pipe (5) leading from it. The exhaust pipe is enclosed completely within the lid, so that gases are released via the lid. The converter element is mounted in such a way that the direction in which the element or its fastening is most sensitive to vibrations is parallel to the crankshaft (7) of the engine.
