    摘要： A muffler has an integrated SCR catalytic converter for an exhaust line of an internal combustion engine, in particular in a motor vehicle The muffler includes a housing which has an intake trumpet on the intake end and an exhaust pipe on the output end. Catalytic converter elements are arranged in the housing with one inlet end in an inlet chamber and with an outlet end in an outlet chamber. An outlet end of the intake trumpet communicates with the inlet chamber. To improve the efficiency of the SCR catalytic converter the inlet chamber is sealed off from the outside and with respect to the intake trumpet and the catalytic converter elements to the extent that in operation of the internal combustion engine with exhaust gas loaded with urea, passing through the intake trumpet into the inlet chamber, the exhaust gas leaves the inlet chamber only through the catalytic converter elements.

    摘要： An exhaust gas-treating device (1) for an exhaust system of an internal combustion engine, especially of a motor vehicle, has a housing (2), which has a jacket (3) extending circumferentially on the side and two end-side end bottoms (4, 5). Maintenance is simplified with at least one mounting tube (6), which passes through one or the first end bottom (4) and into the outlet end (8) of which a particle filter (7) is plugged axially from the outside, with a deflecting housing (9). The deflecting housing (9) contains a deflecting chamber (10), and has at least one inlet (11) communicating with the deflecting chamber (10) and at least one outlet (12) communicating with the deflecting chamber (10). A fastening device (13) is provided for detachably fastening the respective inlet (11) at the respective outlet end (8) of the mounting tube (6).

    摘要： The present invention relates to an exhaust gas treatment device for an exhaust system of an internal combustion engine, more preferably of a road vehicle with a housing, in which at least one exhaust gas treatment element is arranged and mounted by means of a bearing mat and with an outlet pipe which is fluidically connected to an outlet chamber formed in the housing. The risk of a contamination of the bearing mat with water can be reduced with a separating bottom which is arranged in the housing and separates the outlet chamber from a collecting chamber. The separating bottom includes several passage openings through which the outlet chamber is fluidically connected to the collecting chamber and which are each enclosed by a collar protruding into the outlet chamber.

    摘要： An exhaust gas treatment device (1) for an exhaust system of an internal combustion engine, especially of a motor vehicle, has a multipart housing (2), which contains an oxidation-type catalytic converter unit (5) and, downstream therefrom, a particle filter unit (6) one after another in an axial direction extending in parallel to a longitudinal direction (3) of the housing. The housing (2) contains an inlet housing part (7), which has an exhaust gas inlet (8) and the oxidation-type catalytic converter unit (5), and an outlet housing part (9), which has an exhaust gas outlet (10) and into which the particle filter unit (6) axially protrudes. The maintenance of the exhaust gas treatment device is simplified if at least two housing parts (7, 9, 12) axially adjoining each other are detachably connected to one another by means of a clamp connection (11) and if at least one bracket (13) is provided, which is axially rigid in relation to the particle filter unit (6) and which cooperates with at least one such clamp connection (11), such that the bracket (13) is axially fixed at least one housing part (7, 9, 12) by means of the respective clamp connection (11).
