An exhaust system for an internal combustion engine includes an exhaust gas-carrying component (16) with an outer wall (14), a heat conductor element (12) with a jacket (40) and with a heat conductor device (50) enclosed by the jacket (40). A pass-through device (22) provides a gastight passing of the heat conductor element (12) through the outer wall (14) of the exhaust gas-carrying component (16). The pass-through device (22) includes a pass-through opening (26) in the outer wall (14), which pass-through opening (26) is traversed by the heat conductor element (12), and a connection element (24), which is connected in a gastight manner to the heat conductor element (12), on the one hand, and to the outer wall (14), on the other hand.

An exhaust gas treatment assembly unit for an exhaust system of an internal combustion engine includes a tubular outer housing (12) elongated in a direction of an outer housing longitudinal axis (L.sub.A), a tubular inner housing (14) elongated in the direction of an inner housing longitudinal axis (L.sub.I), an exhaust gas treatment unit (16) being carried in the inner housing (14), and a locking fixing device (24) detachably fixing the inner housing in the outer housing. The locking fixing device (24) includes a locking fixing element (26) held at the inner housing (14) in both axial directions with a radially outwards prestressed locking meshing area (28). In association with the locking meshing area (28), a locking receiving area (42) at the outer housing (12), interacts with the locking meshing area (28) for holding the inner housing (14) in the outer housing (12) in at least one axial direction.

The disclosure relates to a conduit connector for a fluid line, having a housing, which has at least one first connection geometry and one second connection geometry, each for connecting to a fluid line. In the housing, a fluid-conducting channel is formed between the first connection geometry and the second connection geometry. In order to avoid damage due to freezing of a liquid located in the channel or the connected fluid lines, the housing has a volume equalization device, which is connected to the channel.

Cassette integrated catalyst for flue gas cleaning comprises one or more depressions in the cassette wall or several of the walls to provide increased structural strength of the cassette and an improved fix of the catalyst monolith or monoliths comprised within the cassette.

A housing for an exhaust system of an internal combustion engine of a vehicle, includes at least two housing shell areas (12, 14) enclosing a housing interior (26) and connected to one another in a connection area (16). A first housing shell area (12) of the two housing shell areas has a first meshing formation (36) in the at least one connection area (16) and a second housing shell area (14) of the two housing shell areas has a second meshing formation (40) that meshes or can be caused to positive-lockingly mesh with the first meshing formation (36). The first meshing formation (36) includes at least one meshing opening (38) and the second meshing formation (40) includes at least one meshing strap (42) meshing with the at least one meshing opening (38) in association with the at least one meshing opening (38) of the first meshing formation (36).

A vehicle exhaust system includes a vehicle body structure, an exhaust system, a rear bumper assembly, an exhaust finisher and a boot. The exhaust assembly is supported to an underside of the vehicle body structure. The rear bumper assembly is also supported to the vehicle body structure. The exhaust finisher is non-movably attached to one of the vehicle body structure and the rear bumper assembly. The exhaust finisher extends at least part way through an opening of the rear bumper assembly. The boot has a first end, a second end, and a flexible portion. The first end is attached to a rear end of the exhaust assembly. The second end is attached to a forward end of the exhaust finisher and the flexible portion extends from the trout end to the second end. The flexible portion is elastically deformable in response to thermal expansion and contraction of the exhaust assembly.

An exhaust gas purifying apparatus for a vehicle includes: a turbocharger having a turbine which rotates by exhaust gas flowing from an engine into an inlet of the turbine; a filter connected to an outlet of the turbine at an inlet of the filter and allowing the exhaust gas passing through the turbine to flow into the filter; and a gasket disposed between the outlet of the turbine and the inlet of the filter to maintain airtightness between the turbine and the filter. A portion of the gasket is exposed toward the turbine or the filter.

An exhaust gas converter body structure includes a main body, an inlet structure, and an outlet structure. The main body is configured to receive an exhaust gas converter between the inlet structure and the outlet structure. The inlet structure and the main body have complementary coupling geometries at a first joint. The outlet structure and the main body have complementary coupling geometries at a second joint. The coupling geometries of each of the inlet structure and the main body are at the first joint asymmetric or reflection-symmetric with respect to exactly one plane of symmetry and/or the coupling geometries of each of the outlet structure and the main body are at the second joint asymmetric or reflection-symmetric with respect to exactly one plane of symmetry. The configuration establishes a given angular position between the inlet structure and the main body and/or between the outlet structure and the main body.

An apparatus includes an exhaust gas purification device configured to be coupled to a cylinder head of an engine via a bracket, the exhaust gas purification device defined by a housing including a body portion, a first end portion, and a second end portion, the body portion interposed between the first end portion and the second end portion, the first end portion configured to be coupled to the bracket.

An assembly for braking the displacement of a tailpipe cover is disclosed. The assembly has a clamping element with an elastic material, a tailpipe, and a tailpipe cover. The clamping element is arranged at least indirectly on the tailpipe and on the tailpipe cover. A section of the clamping element extends over the tailpipe in the axial direction parallel to the longitudinal axis of the tailpipe cover. The distance between the longitudinal axis and the clamping element is designed to be at least partly shorter than the distance between the longitudinal axis and the tailpipe in said clamping element section. Alternatively or in addition thereto, at least one section of the clamping element is arranged at least indirectly against the tailpipe in an immovable manner in the direction of the longitudinal axis.
