23968-361 ABSTRACT In exhaust mufflers fitted with a catalytic converter, when used for portable tools such as power saws, the formation of flames from the exhaust gases which are superheated by the exo- thermic process within the catalytic converter and which still contain fuel and which may escape from the muffler, is to be avoided. To this end the catalytic converter can constitute the connection between separate chambers in a muffler that is at least partially welded, and the muffler can be arranged directly on the engine outlet.
