A connection unit for connecting two exhaust gas-carrying assembly units of an exhaust system of an internal combustion engine, includes a ring washer-shape connection element (26) with a connection side (42), which is to be positioned to face a counter-connection element (24) to be connected to the connection element (26) or/and in contact with the counter-connection element (24). A passage opening (28), bordered by an inner circumferential surface (36) of the connection element (26), receives a connection pipe (30), which is inserted into the passage opening (28) and extends in the direction of a pipe longitudinal axis (L). The connection pipe (30) is connected to the connection element (26) in the area of the inner circumferential surface (36) by welding, or/and the connection pipe (30) projects with a centering section (40) on the connection side (42) of the connection element (26).

An exhaust device includes a housing, first and second pipes, and a spacer. The first and second pipes are at least partially disposed within the housing. The first and second pipes include respective first and second surfaces. A portion of the second pipe is disposed inside the first pipe. The first and second surfaces cooperate to define an annular volume into which the spacer is disposed to prevent direct communication between the first and second pipes. One of the first and second pipes is fluidly connected to an exhaust gas inlet. The other of the first and second pipes is fluidly connected to an exhaust gas outlet. One of the first and second surfaces defines a radial indentation. The other of the first and second surfaces defines a radial protrusion. The spacer is disposed at least partially within the radial indentation and is in direct communication with the radial protrusion.

A shielding element, which comprises at least two sections that are embodied to be linearly connected to each other in abutting fashion on at least one contact surface so as to enclose a three-dimensionally shaped profile or pipe segment of an exhaust line of an internal combustion engine over a certain length when in use. In order to modify a shielding element of the above-mentioned type while amplifying its effect with other positive properties, it is proposed for the sections of the shielding element to each comprise at least one electrical heating system, which, in an installed position, is thermally directed at the pipe segment that is to be enclosed.

In order to improve a sealing system, particularly for sealing against hot gas, it is proposed that it comprise a sealing element or a plurality of sealing elements and a support device for the sealing element or for the sealing elements, wherein the sealing system is constructed such that the one or at least one sealing element is arranged on the support device with play in at least one sealing state of the sealing system.

Clamping apparatus is provided including clamp means for clamping two or more items together in use. The clamping means are arranged to move between a clamped and an unclamped position in use. Attachment means are provided on or associated with the clamping means for attaching one or more components to said clamping means in use. The components consist of any or any combination of one or more sensor means, one or more dispensing means or one or more electronic components. The clamping means includes at least one band member. The at least one band member forms an outer band and the attachment means are provided on or associated with at least an additional band member in the form of an inner band or segment that is provided with or associated with the outer band.

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 component of an exhaust system for an internal combustion engine comprises a wall in which at least one opening is provided. A perforated cover at least partly closes the at least one opening. The perforated cover is mounted on the wall using a holder, and a portion of the perforated cover engages into an opening provided on the holder. There is also presented an exhaust system comprising such a component, and a method for manufacturing such a component, in which the perforated cover is mounted on the holder by introducing at least one portion of the perforated cover into an opening provided on the holder.

An exhaust device includes a casing including an inlet configured to receive an exhaust gas, an outlet configured to discharge the exhaust gas, and a chamber disposed therein between the inlet and the outlet. The casing defines a longitudinal axis along its length. The exhaust device further includes an exhaust conduit at least partially received within the chamber of the casing along the longitudinal axis. The exhaust conduit includes an inner surface, an opposing outer surface, a plurality of perforations extending through the exhaust conduit from the inner surface to the outer surface, and at least one protrusion extending outwardly from the outer surface. The exhaust device further includes an absorptive material disposed on the outer surface of the exhaust conduit. The at least one protrusion of the exhaust conduit engages with the absorptive material in order to form an interference fit between the absorptive material and the exhaust conduit.

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.

An arrangement for fastening a tailpipe cover to a tailpipe is disclosed. The arrangement has a tailpipe cover, a tailpipe and a bracket. The bracket is arranged on the tailpipe cover. The tailpipe cover can be latched here to the tailpipe at a tailpipe projection, which is arranged on the tailpipe, by the bracket being deflected laterally in the circumferential direction of the tailpipe cover.
