Patent ID: 8236249

Claim:
A particle separator for removing particles from an exhaust gas stream of an internal combustion engine, comprising: a prescribed number of flow cells in said particle separator, wherein the exhaust gas stream flows into and/or out of said flow cells via, as viewed in a main direction of flow of the exhaust gas stream, side wall regions of said flow cells, further wherein at least one storage space is formed in said flow cells for storing particles removed from the exhaust gas stream, further wherein the exhaust gas stream is adapted to flow through at least portions of said particle separator, further wherein adjacent ones of said flow cells are in flow communication with one another and each have at least one common flow-through opening, in particular such that this common flow-through opening for one of said flow cells forms an intake opening and for the adjacent, other flow cell forms a discharge opening, further wherein one of said storage spaces of each of said flow cells is formed by at least one blind-end bore type clearance volume space, in particular by at least one blind-end bore type flow cell channel portion, further wherein said blind-end bore type clearance volume space, as viewed in a main direction of flow of the exhaust gas stream, is formed in at least a front end portion of each of said flow cells, further said blind-end bore type clearance volume space, as viewed in a main direction of flow of the exhaust gas stream, is disposed upstream and/or downstream of said at least one flow-through opening, and wherein said blind-end bore type clearance volume space is provided with a baffle base wall that is oriented essentially perpendicular to the main direction of flow of the exhaust gas stream.
