Abstract (en)
[origin: EP1760279A2] The muffler has two pipes (6, 7) on ends of an exhaust inlet (3) or exhaust outlets (4, 5) of a housing (2). One of the pipes (6) is switchable between an open state and a closed state by a control device (8). The pipe is acoustically coupled to a silencer system (12) such that the silencer system is active when the pipe (6) is opened and closed, where the silencer system has a different damping characteristic when the pipe (6) is opened. The silencer system has pipe and chamber volumes (22, 23) that are acoustically coupled to the pipe (6).
