A DEVICE FOR EXHAUST GAS PURIFICATION

摘要

The invention relates to a device for purifying exhaust gases from a combustion engine (1), comprising a first filter (10) arranged in an exhaust conduit (7) between the engine (1) and an exhaust outlet (8) for removing particulate constituents from the exhaust gases, and a recirculation conduit (11) for diverting a part of the exhaust gases that have passed through said first filter (10) and recirculating this part of the exhaust gases to the air intake (2) of the engine. The device further comprises a second filter (30) arranged between the inlet end (20) of the recirculation conduit and the air intake (2) of the engine. The invention also relates to a method for purifying exhaust gases from a combustion engine. Furthermore, the invention relates to the use of the device for exhaust gas purification in particular at a diesel engine.
