    摘要： A particulate filter for separating particulates out of an exhaust gas flow of an internal combustion engine has a filter body with an inflow region and an outflow region. The filter body is formed by alternately arranged inflow ducts that are open toward the inflow region and are closed toward the outflow region, and outflow ducts that are open toward the outflow region and closed toward the inflow region. The filter body has a plurality of substantially planar filter plates arranged parallel to one another. Each of the inflow ducts and the outflow ducts is formed by adjacent filter plates, and is arranged in a housing. The inflow ducts are open at at least one of their lateral regions in such a way that the inflow region extends over at least two sides of the filter body. At least one sealing element is provided for sealing off the filter body in the outflow region relative to the housing.

    摘要： The invention relates to an exhaust gas after treatment apparatus having a hollow cylindrical casing shell (2). In the inside an exhaust catalytic converter, preferably adapted as SCR-catalytic converter, as well as an inflow chamber (9) for exhaust gas to be purified are provided. Therein, the inflow chamber (9) is defined by two bottom portions (10, 11) arranged opposite to each other. Further, a shell portion (12) gas tightly encompassing the bottom portions (10, 11) is provided for the inflow chamber (9). The inflow chamber (9) is encompassed by the casing shell (2) and may be manufactured from a material different from a material of the casing shell.
