Abstract

An upstream portion of a communication passagein an exhaust emission control device has a gas gathering chamberA encircling and gathering exhaust gasfrom an exit end of a particulate filterthrough perpendicular turnabout of the gasand a communication pipeB extracting the gasgathered by the chamberA through an exhaust outletinto an entry side of a selective reduction catalystAn injectoris in the passageto add urea water into the gas flow. The injectoris fixed to the chamberA in a position opposed to the outletand in a direction perpendicular to an axis of the filterThe outletof the chamberA has a reactorinto which the reducing agent injected by the injectoris impinged to facilitate gasification of the gas
