Abstract
The subject invention refers to a muffler comprising a muffler housing ( 1, 2 ) and generally a catalytic converter element ( 13 ) mounted in the housing, which muffler has at least one inner outlet ( 4 ) through which exhaust gases cleaned by the catalytic element ( 13 ) are intended to pass. Furthermore, according to the invention an outlet duct ( 30, 31 ) is arranged in connection to the outside of the housing, comprising a first section ( 30 ) for leading exhaust gases in a first direction (A) in parallel with the outside of the housing, and a second section ( 31 ) for leading exhaust gases in a second, opposite direction (B), whereby said first and second sections ( 30, 31 ) have an essentially equally large cross-sectional area. By way of this outlet duct an improved cooling of the exhaust gases before they are brought in contact with fresh air rich in oxygen can be achieved. A back-pulsation of fresh air into the muffler can also be prevented.
