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).

A conveying device for an aqueous urea solution in a motor vehicle, with a tank, with a filter element and with a pump. The aqueous urea solution can be conveyed by the pump from the tank through the filter element into a suction line, wherein the filter element has a filter material and a frame for receiving the filter material, wherein the filter material is connected to the frame by a connection element, wherein the connection element is part of the fluid conveying path from the tank via the filter element to the pump.

A vehicle includes an exhaust aftertreatment system for use with an automotive internal combustion engine. The system includes a reducing agent mixer configured to deliver a reducing agent for mixing with exhaust gases produced by the engine. The reducing agent mixer includes a mixing can defining an internal space, a doser configured to inject the reducing agent toward the internal space, and a reducing agent delivery device configured to direct the reducing agent into the internal space.

A v-clamp provides an enhanced axial load to tubular body end flanges in order to establish a fluid-tight joint therebetween. The v-clamp, according to an example, has a v-angle that varies in value over a section or more of a band of the v-clamp. The varying v-angle has been shown to effect an axial load that is more evenly and uniformly applied around a circumference of the v-clamp and to the underlying tubular body end flanges. Furthermore, in an example, the tubular body end flanges have a partially spherical shape.

A single-piece tubular shell for an exhaust device includes a first peripheral wall portion, a second peripheral wall portion, and a third peripheral wall portion. The first peripheral wall portion at least partially defines a first interior region having a first longitudinal axis extending therethrough. The second peripheral wall portion at least partially defines a second interior region having a second longitudinal axis extending therethrough. The second longitudinal axis is non-coaxially aligned with the first longitudinal axis. The third peripheral wall portion extends between and connects the first peripheral wall portion and the second peripheral wall portion such that the first interior region and the second interior region are in fluid communication. The first peripheral wall portion, the second peripheral wall portion, and the third peripheral wall portion are integrally formed and define an uninterrupted, smooth shell inner surface.

A vehicle exhaust system includes a tubular component which allow passage of exhaust gases therethrough. The tubular component includes an upstream pipe having a first end and a second end. The tubular component further includes a downstream pipe having a third end and a fourth end. The third end of the downstream pipe at least partially encloses the second end of the upstream pipe such that the upstream pipe and the downstream pipe together define a junction region and the fourth end defines a primary exhaust gas flow path. The downstream pipe at least partially defines an opening within the junction region such that the opening provides a secondary exhaust gas flow path.

A cable connection (16) for a dosing module (6) for exhaust gas reduction, with a dosing module end (16b), which is designed for connection to the dosing module (6), and an end (16a) distant from the dosing module, comprising at least one electrical cable (19a, 19b) having at least one electrical conductor (28a, 28b) and a cable insulation (15a, 15b) surrounding the at least one electrical conductor (28a, 28b). The cable connection (16) is crimped in one region (26a) at the dosing module end (16b) of the cable connection (16). In the crimped region, a space (36) between the at least one electrical conductor (28a, 28b) and the cable insulation (15a, 15b) surrounding the at least one electrical conductor (28a, 28b) is filled with a silicone material (17a, 17b).

A muffler (4) for motor vehicles comprising an intake pipe (8) of the exhaust gases that separates, at a fork (10), into a main pipe (12) and a secondary pipe (16), a muffler body (24) which delimits an expansion volume (28) and houses at least partly the main pipe (12) and the secondary pipe (16), wherein the intake pipe (8) of the exhaust gas is in fluid continuous connection with the main pipe (12) through the secondary pipe (16), and wherein the main pipe (12) comprises, downstream of the fork (10), a throttle valve (32) which allows or prevents a further fluidic connection of the intake pipe (8) of exhaust gas with the main pipe (12), and an output of the exhaust gases (40), for the expulsion of the gases from the muffler pipe (4).

A vehicle component (100) having an exhaust-gas tailpipe device (1) for an exhaust-gas system of a motor vehicle includes at least one exhaust-gas tailpipe (2) and an exhaust-gas tailpipe trim (3) that, in a crash situation, can be pushed at least in sections onto the exhaust-gas tailpipe (2). The exhaust-gas tailpipe device (1) has at least one shield element (4) that is designed for noise optimization and that is fastened in front of the exhaust-gas tailpipe trim (3) by means of at least one predetermined breaking device (5). Thus, in the crash situation, the shield element (4) can be pushed at least in sections onto the exhaust-gas tailpipe (2).

A vehicle includes an exhaust aftertreatment system for use with an automotive internal combustion engine. The system includes a reducing agent mixer configured to deliver a reducing agent for mixing with exhaust gases produced by the engine. The reducing agent mixer includes a mixing can defining an internal space, a doser configured to inject the reducing agent toward the internal space, and a reducing agent delivery device configured to direct the reducing agent into the internal space.
