Abstract
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.
