摘要

The exhaust gas guiding housing (1) or pipe has an internal chamber (12), nitrogen oxides sensor (22) or injecting unit like a injector nozzle, which extends partly, and a carrier bushing (6) or pipe connected with the housing in a detachable or non-detachable manner for the nitrogen oxides sensor or the injecting unit. A support bushing (20) supports the nitrogen oxides sensor or the injecting unit, inserted in a defined rotating position partly in the carrier bushing and is held axially and in torque proof manner by a detachable connection.
