Device for removing soot particles from the exhaust gas flow of an internal combustion engine

摘要

The invention relates to a device for removing soot particles from the exhaust gas flow, particularly of an internal combustion engine, wherein the device is a filter made of porous filter material, through which the gas flows three-dimensionally at least in partial regions from an inlet side to an outlet side. According to the invention, a generic device is further developed such that blocking is safely avoided, even in operating states in which no cleaning of the device occurs over an extended period of time. For this purpose, the filter comprises at least one flow connection (5) connecting the inlet side (2) to the outlet side (3) and having lower flow resistance than the filter material (1), and the flow connection (5) is open toward the filter material (1) at least in partial sections.
