Claim:
An exhaust system for an internal combustion engine, said exhaust system comprising: an exhaust line that carries exhaust gas away from the internal combustion engine; at least one exhaust gas treatment device arranged in said exhaust line; an injection device arranged on said exhaust line upstream from said exhaust gas treatment device for injection of a liquid educt into said exhaust line; a mixing and/or evaporation device arranged in said exhaust line downstream from said injection device and upstream from said exhaust gas treatment device for the injected educt, wherein at least one section of said exhaust line carrying the exhaust gas is formed by an exhaust pipe, said exhaust pipe having an end section arranged downstream from said injection device and upstream from said exhaust gas treatment device, said end section protruding into another upstream or downstream neighboring pipe of said exhaust line or into a housing containing the exhaust gas treatment device, wherein said mixing and/or evaporation device is formed integrally on the end section of said exhaust pipe, and wherein said mixing and/or evaporation device comprises a plurality of baffles, said baffles are shaped so that they impose on the exhaust gas flow a swirling component about the longitudinal central axis of the exhaust pipe.
