Abstract: A particle separator for treating the exhaust gases of an internal combustion engine includes at least one metallic layer through which exhaust gas can flow. The metallic layer is located in a housing that includes an inlet opening, an outlet opening and a central axis. The housing is provided with at least one inspection or maintenance opening that laterally penetrates the housing and provides a passage through to the metallic layer. The particle separator can, in particular, remain operational without having to be dismantled or can autonomously remain fully open to a flow at all times. A motor vehicle having at least one particle separator is also provided.

Abstract: A particle separator for treating the exhaust gases of an internal combustion engine includes a housing having an inlet opening, an outlet opening, a cross section and a central axis. At least one metallic layer, through which exhaust gas can flow, is located in the housing and has an undulation or corrugation that spans the cross section of the housing. The particle separator has a large surface for providing the lowest possible flow resistance and a low risk of clogging. A motor vehicle having at least one particle separator is also provided.

Abstract: A particle separator for treating exhaust gases from an internal combustion engine includes a housing having an inlet opening, an outlet opening, a central axis, a first part with a first joining surface and a second part with a second joining surface. The first and second joining surfaces correspond to one another, so that the first and second parts can be positioned along the central axis relative to one another. At least one metallic layer, through which exhaust gas can flow, spaces the first and second joining surfaces apart over the entire circumference. The particle separator can be manufactured cost-effectively in a simple manner with few measures and, in particular, is suitable for retrofitting to an existing exhaust system. A method for producing the particle separator and a motor vehicle having the particle separator are also provided.

Abstract: A hollow body for capturing particles includes at least one at least partially permeable wall extending between two at least partially oppositely disposed openings and along a first longitudinal direction. The hollow body has a primary cross-sectional shape defining a first cross-sectional area. At least one of the openings defines a second cross-sectional area. The second cross-sectional area is greater than the first cross-sectional area. An exhaust-gas treatment device having an exhaust line and a motor vehicle having an exhaust-gas treatment device are also provided.

Abstract: A particle trap disposed between an exhaust gas line and an exhaust gas recirculation line includes at least one partially permeable hollow body separating the exhaust gas recirculation line from the exhaust gas line. The at least one partially permeable hollow body has a wall defining a primary shape with an inner space having at least one open side. The wall is gas-permeable and has a secondary structure with elevations and depressions. An automobile having a particle trap is also provided.
