A muffler with catalytic converter ( ) in which at least one catalytic converter element ( ) is located in the muffler so that an essential part of all exhaust gases ( ) from the engine are forced to pass through the element ( ) and be converted there into cleaned exhaust gases ( ). The element is designed as an essentially self-supporting body of catalytic material, which is hollow or partly concave and has inner and outer surfaces ( ), e.g. the body is shaped as a circular or non-circular sleeve, or possibly even as a narrowing sleeve ( ), a dome-shaped or angular bowl-shaped body ( ), and the element is, either directly or via intermediary elements, mounted to a dividing part inside the muffler, such as a partition wall ( ), an outlet duct ( ) or an inlet duct ( ), and the mounting is so arranged that at least one end surface ( ) is kept fixed at the same time as the element is supported at the outer surface ( ) by at least one part ( ), while the inner surface is essentially free.

Muffler with catalytic converter

Muffler

Spark arresting structure for a muffler having a catalytic converter

Muffler with catalytic converter (1) composed of a muffler housing (2) and a lid (3) which seals the muffler housing. A catalytic converter element is mounted in the lid and an exhaust pipe (5) leads from this element out of the muffler (1). The exhaust gas pipe (5) is located entirely in the lid, so that the exhaust gases are released via the lid (3).
