Abstract (en)

The invention relates to a sound-absorbing exhaust system for an internal combustion engine. The system comprises a receptacle (2), an inlet (3) which is arranged in the receptacle (2) and through which exhaust gases can be directed into the same, and a discharge pipe (4), which connects the interior of the receptacle (2) to the ambient air and through which exhaust gases can be discharged from the same. The discharge pipe (4) has, at its end positioned outside the receptacle (2), a seal (5), which substantially seals the discharge pipe (4) at this end. The discharge pipe (4) has at least one, but preferably a plurality of radial holes (6), which are positioned outside the receptacle (2). The system further has a sleeve (7), which wholly or partially surrounds the discharge pipe (4) outside the receptacle (2). This arrangement reduces the emission of exhaust gas noise from the system. <IMAGE>
