Abstract

See full text

An exhaust system injection section (10) includes an exhaust gas flow channel (19), a laterally arranged injector connection (21), with a fluid introducing injector (22) and an injection chamber (24) formed in the channel, which is delimited by a perforated first separating wall (25), arranged in the channel upstream of the injector connection, and a perforated second separating wall (26) arranged in the channel downstream of the injector connection. To provides intensive mixing of the injected fluid with the exhaust gas flow a perforation (29) of the first separating wall (25) is configured so that exhaust gas largely flows eccentrically through the first separating wall (25) with respect to a longitudinal center axis (23) of the channel and a perforation (31) of the second separating wall (26) is configured so that exhaust gas largely flows concentrically through the second separating wall (26) with respect to the longitudinal center axis (23).
