摘要： An assembly unit 1 of an exhaust system has at least one and particularly two connection funnels 2 made of cast material and a pipe 3. The at least one connection funnel 2 has a pipe socket 21 and at least one bracket 22. The bracket 22 is arranged outside of the pipe socket 21. A connection section 31 of the pipe 3 is fastened to the bracket 22 of the at least one connection funnel. The pipe socket 21 extends beyond the connection section 31 of the pipe 3 into the interior of the pipe 3 and is spaced apart from an inner wall of the pipe 3 by at least the simple wall thickness of the pipe 3.

摘要： 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).

摘要： A method for producing an exhaust-gas aftertreatment device inserts a monolith in a housing, assembled from a circumferentially enclosed jacket and two end funnels. The monolith is axially inserted into the jacket with a circumferentially enclosing support mat. The funnels are connected to the jacket via an axial connecting section shaped complementary to the cross-section of the jacket, such that each connecting section and an axial end section of the support mat axially overlap. The jacket, including the connecting sections of the funnels are reduced from a starting cross-section to an end cross-section. This produces a predetermined radial preload in the support mat in a support area extending from the one connecting section to the other connecting section to retain the monolith in the jacket.

摘要： An exhaust gas stream for an internal combustion engine includes a muffler housing (12) with a first chamber (14) and a second chamber (16). An exhaust gas inlet (24) has a first chamber opening area (30) and a second chamber opening area (32). An exhaust gas outlet (36) is open in an outlet opening area (42) towards the first chamber. A connection opening (50) is provided between the first chamber and the second chamber and has an exhaust valve arrangement associated therewith, including a valve element (56) including a closing area (58) closing the connection opening in a closed position of the exhaust valve arrangement (52). The exhaust valve arrangement includes an actuating area (64) associated with the inlet second opening area for generating an actuating force acting on the exhaust valve arrangement, moving from the closed position in the direction of an open position by exhaust gas bypass flow.

The sound generator (4) has an emission pipe (16), which connects the sound generator (4) acoustically and fluidically directly with an emission chamber (17). The an emission chamber (17) emits the sound generated by the converter (10) during the operation of the sound generator (4).

摘要： An exhaust device (2) for an internal combustion engine (3) has an exhaust line (5) with a rear section X with two exhaust pipes (11) connected to an acoustic actuator (12) in a sound-transmitting manner. Better acoustic characteristics and increased number of noises audible from the outside is guaranteed by the exhaust pipes (11) being of different designs and/or by the actuators (12) being able to be actuated individually. A process for controlling the actuators (12) uses a control device (25) that actuates the actuators (12) individually to generate different acoustic signals (23) of the respective actuators (12). A motor vehicle (1) is provided with such an exhaust device (2) with acoustic actuators (12) controlled by such a process. The motor vehicle (1) has additional actuators (29, 31), which are especially associated with an intake line (30) and are arranged in the interior of motor vehicle (1).

摘要： A static mixer for the through-mixing of a flow in a line conducting the flow, more preferably of an exhaust system of a combustion engine with several guide vanes. To create adequate through-mixing at low flow velocity and a through-flow resistance that is not too high at high flow velocity, the guide vanes are produced of a shape memory alloy wherein below a predetermined limit temperature the guide vanes have at least one low-temperature shape and above the limit temperature the guide vanes have at least one high-temperature shape, which differs from the low-temperature shape through a reduced through-flow resistance of the mixer.
