Abstract: A component (6) of an exhaust system (1) for an internal combustion engine (3), of a motor vehicle, has a housing including a shell (12), two end bottoms (13, 14) and an intermediate bottom (15, 16). The shell (12) encloses an interior space (18) of the housing (11) in a circumferential direction (19). The two end bottoms (13, 14) delimit the interior space (18) in an axial direction (17) at opposite ends and are fixed to the shell (12). The intermediate bottom (15) is arranged in the interior space (18) axially between the end bottoms (13, 14) and is radially supported on the shell (12). A holding pipe (22), for connection of the component (6) to a system periphery (9), is radially held on the intermediate bottom (15) in the interior space (18), passes through one end bottom (13), is fastened thereon and is closed off in a gas-tight manner.

Abstract: A mixer (19), for an exhaust system (7) for mixing and/or evaporating a liquid (13) in an exhaust gas flow (8), especially for an SCR system (9), includes a plurality of guide blades (21) arranged in a star-shaped pattern. Simplified manufacturability of the mixer (19) is achieved if the guide blades (21) are connected each with a centrally arranged core (23) radially on the inside and if the guide blades (21). The guide blades (21) and the core (23) are formed by an integral cast part (24).

Abstract: An injection device (14), for introducing a reducing agent (11) into an exhaust gas stream (8) of an exhaust system (7) of an internal combustion engine (1), has an exhaust pipe (15) for guiding the exhaust gas stream (8), which has a connecting piece opening (18) in a wall (17). A connecting piece (16) is inserted with an inner end (19) into the connecting piece opening (18) and is provided for connecting an injector (10) at an outer end (20). Simplified assembly is achieved if the connecting piece (16) has, at an inner end (19), a laterally projecting, fully circumferentially extending collar (22). The collar (22) is in contact, on an inner side (23) of the wall (17), with an opening edge (24) enclosing the connecting piece opening (18) and is welded to the wall (17).
