  • Patent number: 11591945
    Abstract: An exhaust gas treatment arrangement for an exhaust gas system of an internal combustion engine includes an exhaust gas channel leading to a flow path switching unit. The flow path switching unit is configured for changing exhaust gas parts of an exhaust gas stream flowing through the exhaust gas channel, which are conducted into first and second exhaust gas flow paths downstream of the flow path switching unit. The first exhaust gas flow path and the second exhaust gas flow path lead to an exhaust gas outlet. An SCR catalyst unit is in the first exhaust gas flow path upstream of the exhaust gas outlet. A liquid bypass line drains liquid from a liquid collection region in the exhaust gas channel upstream relative to the switching unit. The liquid is drained to a liquid discharge region for discharging liquid into the second flow path downstream of the switching unit.

  • Patent number: 8888059
    Abstract: A fastening device (6) for detachably fastening a first component (4) to a second component (5), especially to a motor vehicle. A bearing block (7), which has a stay bolt (13), is fastened to one component (5). The bearing block (7) has an anchor bracket (8), which is fastened to the other component (4) and which has an anchor hook (15) for hooking onto the stay bolt (13). A locking device (16) is provided which can be adjusted between a locking state, in which anchor hook (15) can be hooked into and detached from the stay bolt (13), and an unlocking state, in which stay bolt (13) is fixed to the anchor hook (15) hooked into same.

  • Publication number: 20090211214
    Abstract: The invention relates to a filter plate for a particulate filter which serves to separate particulates out of an exhaust gas flow of an internal combustion engine. A filter plate for a particulate filter which serves to separate particulates out of an exhaust gas flow of an internal combustion engine is proposed, which filter plate is composed of a substrate material, which is permeable to gas and is coated with a sintered metal powder, and has a surface region which extends substantially in a plane. It is provided according to the invention that the surface region (2) is provided with alternating linear depressions (3) and elevations (4), with a section (2a) of the planar surface region (2) remaining at least between two successive depressions (3) or elevations (4). The filter plate is suitable for the construction of a particulate filter which serves to separate particulates out of an exhaust gas flow of an internal combustion engine.

  • Publication number: 20080168754
    Abstract: The invention relates to an exhaust particulate filter with a filter body (4), comprising a number of filter pockets (3) arranged one behind the other and formed by filter plates (1), the filter plates (1) having a planar cutout opening (2). According to the invention, it is provided that the peripheral contour (8) of the planar cutout opening (2) comprises points which are located at different distances from the centroid (S) of the area of the cutout opening (2). For an exhaust particulate filter according to the invention, it is further provided that the centroid (S) of its at least one area of the cutout opening (2) is arranged at a distance from the central longitudinal axis (7) of the filter body (4) on the filter plate (1) or that the filter body (4) has filter plates (1) with different cutout openings (2). The exhaust particulate filter is suitable in particular for an application in motor vehicles with a diesel engine.
