ABSTRACT:
A device for purifying exhaust gases from a combustion engine (1) is provided with a first filter (10) arranged in an exhaust conduit (7) between the engine (1) and an exhaust outlet (8) for removing particular constituents from the exhaust gases, and a recirculation conduit (11) for diverting a part of the exhaust gases passing through the first filter (10) recirculating this part of the exhaust gases to the air intake (2) of the engine. A second filter (30) is arranged between the inlet end (20) of the recirculation conduit and the air intake (2) of the engine. A method for purifying exhaust gases from the combustion engine (1) and using this device to purify exhaust gas, in particular, from a diesel engine, are also provided.
