摘要： A method provides for manufacturing a flap carrier for an exhaust gas flap, especially for the exhaust gas stream of an internal combustion engine. The method includes providing a flap housing (50) and providing a stop ring (48). The stop ring (48) is inserted into the flap housing (50) in a position corresponding to an installed position. The stop ring (48) is fixed to the flap housing (50). Subsequently to fixing the stop ring (48) to the flap housing (50), at least one shaft opening (60, 62) for a pivot shaft carrying a flap diaphragm with at least one flap wing is inserted into the stop ring (48).

摘要： An exhaust gas muffler, for an exhaust system of an internal combustion engine, includes a muffler housing (12) with a circumferential wall (14) elongated in a housing axis (L) direction and with an end wall (20, 22) at each axial end area (16, 18). Two exhaust gas pipe holding openings (44, 46) are provided in the circumferential wall (14) with an exhaust gas pipe (40) fixed to the circumferential wall (14) in an area of each exhaust gas pipe holding opening (44, 46) and open towards a housing interior (24). The exhaust gas pipe (40) is preferably closed at one end area (54) by a closing element (58). The exhaust gas pipe (40) has at least one exhaust gas passage opening (66) in a length area (64) extending between the two exhaust gas pipe holding openings (44, 46).

摘要： A coupling device (32) provides a rotary coupling of a pivot shaft (18) of a flap diaphragm (16) of an exhaust gas flap (10) with a drive element (34). The pivot shaft is to be rotated about a pivot axis (A). The coupling device (32) includes a first coupling part (36) with a first coupling area configured for coupling with the pivot shaft (18) and a second coupling part (38) with a second coupling area configured for coupling with the drive element (34). The first coupling part (36) and the second coupling part (38) are in a rotary coupling positive-locking meshing state with one another in the coupled state and are supported on one another in the direction of the pivot axis (A).

摘要： A muffler for an exhaust system of an internal combustion engine, especially for vehicles with hybrid drive, includes a muffler housing (12), a heat exchanger unit (48), arranged in the muffler housing (12), for transferring heat from combustion exhaust gas to a heat transfer medium, an inlet pipe (38), a first outlet pipe (52) and a second outlet pipe (40). A first exhaust gas flow path (54), in the muffler housing, routs exhaust gas through the heat exchanger unit (48) to the first outlet pipe (52). A second exhaust gas flow path (56), in the muffler housing, routs exhaust gas to a second outlet pipe (40), bypassing the heat exchanger unit (48). A flow path blocking/releasing device (58) for blocking and releasing at least one exhaust gas flow path (54, 56), of the first exhaust gas flow path (54) and of the second exhaust gas flow path (56).

摘要： A reactant release arrangement for an exhaust gas stream of an internal combustion engine has an exhaust gas guide element (12) with an exhaust gas flow duct (13). A reactant release body (14) extends into the exhaust gas flow duct (13) and has a reactant-receiving volume (20) with a wall inner surface (32) and a wall outer surface (18) of a body wall (16) that is open to the exhaust gas flow duct (13) via at least one passage opening (44, 46). Exhaust gas (G) flowing in the exhaust gas flow duct (13) flows around the reactant release body (14) at a wall outer surface (18) of the body wall (16). A reactant release unit (22) releases reagent (M) into the reactant-receiving volume (20). A heating device (38) is associated with an area of the inner surface (32) of the body wall (16) and heats the reactant release body (14).

摘要： A muffler for an exhaust system of an internal combustion engine includes a housing with a circumferential wall. At least one resonator chamber (48) is defined by the circumferential wall and two base walls (28, 22), that are provided in the housing. At least one resonator pipe (50), with a first pipe end (51) and with a second pipe end (56), is connected to one of the base walls (28) in the area of a first opening (52) in the one of the base walls (28). In the alternative or in addition the one of the base walls (28) traverses an interior space such that the first pipe end (51) lies outside of the resonator chamber (48), with the second pipe end (56) being fixed to the other base wall (22).

摘要： A support unit for supporting an exhaust system of a vehicle includes a first connecting element (26), a second connecting element (28) and at least one coupling element (30) coupling the first connecting element with the second connecting element. A first coupling element passage opening (38) is provided in the first connecting element and a second coupling element passage opening (40) is provided in the second connecting element. The coupling element passes through the first coupling element passage opening (38) and the second coupling element passage opening. A coupling element clamping area is provided in a first longitudinal area (L1) of at least one first coupling element passage opening and a coupling element clamping release area (44) is provided in a second longitudinal area (L2) of this first coupling element passage opening. The coupling element clamping area has a greater thickness than the coupling element clamping release area.
