ABSTRACT:
An exhaust gas recirculation device for an internal combustion engine has a filter for trapping particulates in a recirculation gas, which is arranged in a recirculation gas route, and a device for generating a reverse air flow in which a pure gas flow for the reverse air flow passing through said filter in a reverse direction with respect to a recirculation gas flowing direction in the filter is generated. In the exhaust gas circulation device, the trapped gases are discharged out of the filter by the reverse air flow and are not returned into the internal combustion engine due to an engine exhaust pressure.
