  • Patent number: 11156142
    Abstract: An exhaust system for an internal combustion engine includes an oxidation catalytic converter unit (12) with a first catalytic converter housing with a first housing axis (A1). An SCR catalytic converter unit (18) has a second catalytic converter housing (20), with a second housing axis (A2). A mixer housing (16) has an upstream connection area (24) adjoining a downstream end (26) of the first catalytic converter housing (14) and has a downstream connection area (28) adjoining an upstream end (30) of the second catalytic converter housing. A mixer (48) is carried in the mixer housing. A reactant release device (56) at the mixer housing releases reactant into a reactant-receiving duct (72) of the mixer. The mixer housing includes a first housing part (36) forming the upstream connection area (24) and a second housing part (38) forming the downstream connection area together with the first housing part.
