Abstract
A muffler for an exhaust system of an internal combustion engine includes a muffler housing (14) and at least one exhaust gas pipe group (19). The at least one exhaust gas pipe group (19) includes an outlet pipe (20) open towards an expansion chamber (26) formed in the muffler housing (14). Exhaust gas introduced via the at least one exhaust gas pipe group (19) leaves the muffler housing (16) via the outlet pipe (20). A first inlet pipe (38), of the at least one exhaust gas pipe group (19), has an inlet pipe end area (40), which is inserted into the outlet pipe (20) and extends in the outlet pipe (20). A second inlet pipe (48), of the at least one exhaust gas pipe group (19), is open towards the expansion chamber (26).
Claims20
A muffler for an exhaust system of an internal combustion engine, the muffler comprising:
- a muffler housing defining an expansion chamber;
- and
- at least one exhaust gas pipe group comprising:
- an outlet pipe open to the expansion chamber, wherein exhaust gas introduced via the at least one exhaust gas pipe group leaves the muffler housing via the outlet pipe;
- a first inlet pipe with an inlet pipe end area inserted into the outlet pipe and extending a distance in the outlet pipe;
- and a second inlet pipe open to the expansion chamber.
An exhaust system for an internal combustion engine, the exhaust system comprising:
- an exhaust gas duct system;
- and a muffler comprising a muffler housing defining an expansion chamber and at least one exhaust gas pipe group comprising an outlet pipe open to the expansion chamber, wherein exhaust gas introduced via the at least one exhaust gas pipe group leaves the muffler housing via the outlet pipe, a first inlet pipe with an inlet pipe end area inserted into the outlet pipe and extending a distance in the outlet pipe;
- and a second inlet pipe open to the expansion chamber, wherein the exhaust gas duct system sends exhaust gas to the first inlet pipe and to the second inlet pipe.
A muffler for an exhaust system of an internal combustion engine, the muffler comprising:
- a muffler housing defining an expansion chamber;
- an outlet pipe passing through said muffler housing and having an opening inside said expansion chamber;
- a first inlet pipe passing through said muffler housing with an inlet pipe end area inserted into said outlet pipe and extending a distance into said outlet pipe;
- and a second inlet pipe passing through said muffler housing and opening to said expansion chamber.
