Abstract

An internal combustion engine, exhaust system, exhaust gas treatment device includes an housing (18) including a housing inlet (34) and a housing outlet (60). An exhaust gas treatment unit (28), in the housing, includes an inlet (32) following the housing inlet and an outlet (38). An SCR catalytic converter device (30), in the housing, includes an SCR catalytic converter device inlet (54) following the exhaust gas treatment unit outlet and an SCR catalytic converter device outlet (56). A reactant releasing device (52) releases reactant upstream of the SCR catalytic converter device inlet. An exhaust gas duct (42), formed in an exhaust gas pipe (44), leads in the housing from the exhaust gas treatment unit outlet to the SCR catalytic converter device inlet, whereby exhaust gas leaving the SCR catalytic converter device at the SCR catalytic converter device outlet flows around the exhaust gas pipe in at least some areas.
