    摘要： Provided is an exhaust gas retreatment device for an exhaust system of an internal combustion engine including a housing, in which an exhaust gas retreatment element and upstream thereof a silencer device are arranged, an inlet gas path leading from one housing inlet to an outlet of the exhaust gas retreatment element located in the interior of the housing, with an exhaust gas path following the inlet gas path which in the interior of the housing leads to the silencer device and/or through the silencer device as well as to a housing outlet. A cost-effective design can be achieved if the inlet gas path has a higher gas tightness than the exhaust gas path and/or if components of the exhaust gas retreatment device limiting the inlet gas path have a higher material quality than components of the exhaust gas retreatment device only limiting the exhaust gas path.

    摘要： The present invention relates to an exhaust gas treatment system for an exhaust system of an internal combustion engine, and comprises a basic housing and an add-on housing mounted thereon so it is at least partially detachable. The basic housing contains at least one inlet pipe which can be connected to the exhaust system and leads into the basic housing, at least one outlet pipe which can be connected to the exhaust system and leads out of the basic housing, at least one SCR catalyst and at least one oxidizing catalytic converter. The add-on housing contains at least one particle separation device and at least one reducing agent feed mechanism.

    摘要： The present invention relates to a muffler (1) having an integrated SCR catalytic converter (9) for an exhaust line of an internal combustion engine, in particular in a motor vehicle, having a housing (2) which has an intake trumpet (6) on the intake end and an exhaust pipe (7) on the output end. Catalytic converter elements (10) are arranged in the housing (2) with one inlet end (12) in an inlet chamber (11) and with an outlet end (14) in an outlet chamber (15). An outlet end (23) of the intake trumpet communicates with the inlet chamber (11). To improve the efficiency of the SCR catalytic converter (9) the inlet chamber (11) is sealed off from the outside and with respect to the intake trumpet (6) and the catalytic converter elements (10) to the extent that in operation of the internal combustion engine with exhaust gas loaded with urea, passing through the intake trumpet (6) into the inlet chamber (11), the exhaust gas leaves the inlet chamber only through the catalytic converter elements (10).
