EXHAUST GAS TREATMENT DEVICE WITH REPLACEABLE INSERT

摘要

An exhaust gas treatment device (1), for an exhaust system of an internal combustion engine, includes a tubular housing (2) and an insert (5) arranged replaceably in the housing (2). The insert (5) has an exhaust gas treatment element (7) fixed in a tubular jacket (6) and is able to be pushed into the housing (2) in a pushing-in direction (9), which extends parallel to a central longitudinal axis (10) of the housing (2). The jacket (6) has, on an outer side (15), an axial stop (14), axially in contact with an axial counterstop (18) in the pushing-in direction (9) and is formed on the housing (2) on an inner side (17). A locking element (19) is axially supported on a support contour (20), is formed on the jacket (6) in the pushing-in direction (9), and is provided on the inner side (17) of the housing.
