摘要： An exhaust gas treatment assembly includes a housing and an exhaust gas treatment section accommodating chamber in the housing for accommodating an exhaust gas treatment section therein so as to permit the treatment section to be removed from the housing. An exhaust gas supply duct leads to the housing and is open to the housing via a housing inlet region. A main mixing section accommodating chamber accommodates a main mixing section in such a way that the main mixing section can be removed from the housing. A first exhaust gas treatment section inlet region is open to the housing inlet region to receive exhaust gas from the exhaust gas supply duct. A first exhaust gas treatment section outlet region is open to a main mixing section exhaust gas inlet region of the main mixing section.

摘要： An exhaust gas treatment assembly for an exhaust gas system of an internal combustion engine includes a housing defining a longitudinal axis. A first exhaust gas treatment unit is inserted in the housing and has a first casing and at least one first exhaust gas treatment unit carried in the first casing. A second exhaust gas treatment unit is inserted in the housing and has a second casing and at least one second exhaust gas treatment unit carried therein. A locking arrangement is for locking a first exhaust gas treatment unit in the housing at least against movement in the direction of the longitudinal axis in a locked state, wherein, when the first exhaust gas treatment unit and the second exhaust gas treatment unit are inserted in the housing, the locking arrangement is blocked in the locked state by the second exhaust gas treatment unit.

摘要： In a modularly configured exhaust gas treatment arrangement, a first module includes an entry interface and a first mixing section, a second module includes a first deflection housing and a first catalytic converter arrangement of a first exhaust gas treatment section. The second module is detachably connected to the first module and a third module includes a particle filter arrangement of the first exhaust gas treatment section. The third module is detachably connected to the second module and a fourth module includes a second deflection housing. The fourth module is detachably connected to the third module. A fifth module includes a second mixing section, a third deflection housing, and a second exhaust gas treatment section and the fifth module is detachably connected to the fourth module.

摘要： An exhaust gas treatment assembly for an exhaust system of an internal combustion engine includes a housing having a circumferential wall and at least one base wall which in an external circumferential region is connected to the circumferential wall. In a housing interior space, which is defined by the circumferential wall and the base wall, at least one exhaust gas treatment unit is positioned so as to be removable from the housing. At least one base wall is an interchangeable base wall which is releasably connected to the circumferential wall via a connection assembly. The connection assembly includes a first connection portion, a first axial support portion, and on the base wall includes a second connection portion which via at least one connection member is releasably connected to the first connection portion and a second axial support portion is supported on the first axial support portion.
