摘要: A mixer (19), for an exhaust system (7) for mixing and/or evaporating a liquid (13) in an exhaust gas flow (8), especially for an SCR system (9), includes a plurality of guide blades (21) arranged in a star-shaped pattern. Simplified manufacturability of the mixer (19) is achieved if the guide blades (21) are connected each with a centrally arranged core (23) radially on the inside and if the guide blades (21). The guide blades (21) and the core (23) are formed by an integral cast part (24).

摘要: An exhaust system (1) of an internal combustion engine includes an oxidation catalytic converter (2), a particle filter (3), an injector (4) for injecting a reducing agent, a static mixer-evaporator (5), an SCR catalytic converter (6) and a housing (8). The oxidation catalytic converter is upstream of the particle filter and upstream of the SCR catalytic converter. The injector is upstream of the mixer-evaporator and the mixer-evaporator is upstream of the SCR catalytic converter. The housing has a centrally inner channel (9), a ring channel (10) concentrically around the inner channel, an eccentrically outer channel (11), a first deflecting chamber (12) connecting the outer channel with the ring channel and a second deflecting chamber (13) connecting the inner channel with the ring channel. The mixer-evaporator is in the inner channel and the oxidation catalytic converter or particle filter or SCR catalytic converter is ring-shaped and in the ring channel.
