Cleanable particle separator and motor vehicle having at least one particle separator

摘要

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.

1. A particle separator for the treatment of exhaust gases of an internal combustion engine, the particle separator comprising:
a housing having an inlet opening, an outlet opening, a central axis and at least one inspection opening extending laterally through said housing; and at least one metallic layer through which exhaust gas can flow; said at least one metallic layer disposed in said housing and said at least one inspection opening providing a passage to said at least one metallic layer, said at least one metallic layer being a single metallic layer defining one areal structure completely spanning a cross section of said housing, said at least one metallic layer having at least one depression for accumulating particles retained by said at least one metallic layer, said at least one depression being a three-dimensionally shaped undulation of said at least one metallic layer, said undulation extending through the housing, an extent of said undulation being first delimited by opposite housing wall portions of said housing, said passage extending up to said at least one depression, said at least one depression of said at least one metallic layer extending to said housing and said passage being disposed on a level with said at least one depression, said at least one inspection opening having at least one separate casing extending into an interior of said housing up to said at least one metallic layer.
