A muffler for an exhaust gas system of an internal combustion engine. The muffler has a muffler housing having at least two interconnected housing shells delimiting a muffler interior. Each housing shell has a connecting edge extending away from the muffler interior. The housing shells are mutually connected by material bonding in the region of their mutually adjacent housing shell connecting edges. An insulating arrangement covers at least regions of the inner side of one of the housing shells. The insulating arrangement has an insulating shell with an insulating shell connecting edge extending away from the muffler interior and the insulating shell is arranged with the insulating shell connecting edge between the mutually adjacent connecting edges of the housing shells and is connected by material bonding to the connecting edges of the housing shells in the region of the insulating shell connecting edge.

A muffler for an exhaust system of an internal combustion engine includes a muffler housing having a peripheral wall elongated along a longitudinal housing axis. The muffler has an end wall on each axial end region of the peripheral wall and a muffler insert, surrounded by the peripheral wall and supported on the peripheral wall. A retaining wall extends substantially in the direction of the longitudinal housing axis and a first exhaust-gas routing pipe is positioned with a first end region engaging in an opening in the peripheral wall and is secured to the peripheral wall and retained with a second end region on the retaining wall. The first exhaust-gas routing pipe is retained in its second end region on the retaining wall by force closure or interlocking.

A profile clamp with a clamp band and an annular ring element with a ring body is provided. The clamp band has two clamping heads which are connected to one another via a clamping element. The ring element includes at least one first latching tab, which is arranged projecting from the ring body in the axial direction of the profile clamp and projecting out of the profile clamp at least in some sections. The first latching tab has a first latching portion and a free-swinging portion extending opposite thereto. The first latching portion is designed to exert a force, and the first latching portion has a first contact edge that is designed to create a point contact or a line contact with a flange of the pipe end.

A silencer for an exhaust gas system of an internal combustion engine includes a silencer housing which surrounds a silencer interior and which has at least two housing portions which are adjacent to each other in an abutment region. The two housing portions are connected to each other. The silencer housing has at least one housing opening formed therein and an outlet pipe extends through the silencer housing in the region of the housing opening. The housing opening is completely formed in one of the two housing portions.

A muffler for an exhaust system of an internal combustion engine includes a muffler housing having a peripheral wall elongated along a longitudinal axis of the muffler housing. The peripheral wall has first and second end walls. A muffler insert is surrounded by the peripheral wall and is supported thereon. The muffler insert has a retaining wall extending in a direction of the longitudinal axis. The peripheral wall has a peripheral wall opening and a first exhaust-gas routing pipe has a first end region and is positioned with the first end region thereof engaging in the peripheral wall opening. The first exhaust-gas routing pipe has a second end region and is secured by the second end region thereof to the retaining wall. The first exhaust-gas routing pipe is of multi-part configuration and has a first pipe part and a second pipe part.

An exhaust gas system for an internal combustion engine includes at least one component which delimits an exhaust gas flow volume via an outer wall and, on an inner side of the outer wall which faces the exhaust gas flow volume, supports at least one shielding element. An intermediate space is formed between the outer wall and the shielding element. At least one connecting molding on the shielding element is directed toward the outer wall and is connected fixedly to the outer wall.

An isolator for supporting an exhaust component from a portion of a vehicle via a hanger includes elastomeric isolator element having at least one aperture adapted to receive the hanger and an isolator or bracket for receiving and supporting the elastomeric isolator element. The isolator bracket includes a mounting structure including a first aperture and a second aperture. The isolator bracket is adapted to be fixed to the vehicle by a single fastener extending through the first aperture. The second aperture extends through the isolator bracket and includes an internal wall shaped as a polygon. A target orientation of the isolator bracket relative to the vehicle is obtained when the internal wall of the second aperture is angularly oriented and coaxially aligned with a corresponding aperture in the portion of the vehicle having an internal surface with the same polygon shape as the second aperture.

A device for treating exhaust gases which has an outer wall which has an opening in order to electrically contact one or more conductor tracks, which are arranged within an interior space that is surrounded by the outer wall, through the outer wall. The opening is arranged in a projection which protrudes outward from the interior space and is integrally formed with the outer wall.

An exhaust gas heating element comprises a wafer that is substantially cylindrical with an axis and is made of metallic foam. A flexible, electrical insulating sheet covers an edge of the wafer with an overlap on each face of the wafer. A rigid assembly ring, a housing, and two electrodes are also provided. The rigid assembly ring is made from a cylinder trunk, at least a first edge of which is serrated in such a way as to be able to immobilize the wafer and the flexible, electrical insulating sheet in the rigid assembly ring by folding teeth, substantially at 90°.

An isolator for supporting an exhaust component from a portion of a vehicle via a hanger includes elastomeric isolator element having at least one aperture adapted to receive the hanger and an isolator or bracket for receiving and supporting the elastomeric isolator element. The isolator bracket includes a mounting structure including a first aperture and a second aperture. The isolator bracket is adapted to be fixed to the vehicle by a single fastener extending through the first aperture. The second aperture extends through the isolator bracket and includes an internal wall shaped as a polygon. A target orientation of the isolator bracket relative to the vehicle is obtained when the internal wall of the second aperture is angularly oriented and coaxially aligned with a corresponding aperture in the portion of the vehicle having an internal surface with the same polygon shape as the second aperture.
