    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.
