An exhaust gas purification device includes an upstream cylinder, a downstream cylinder, and a purifying cylinder. The upstream cylinder, the purifying cylinder, and the downstream cylinder each have at an end thereof a flange portion having a flat connecting surface. Each flange portion of one of the upstream and downstream flange portions of the purifying cylinder, and the flange portions of the upstream cylinder and the downstream cylinder includes an engagement pin having an engagement recess portion. Each flange portion of the other includes a pin hole and an engagement groove. The engagement recess portion is fitted into and engaged with the engagement groove.

An exhaust tailpipe/emissions filter employs a reusable/replaceable insert and is configured to slide into and/or onto the exhaust tailpipe of an automobile to reduce air pollution.

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 device for an internal combustion engine of a saddled vehicle includes an exhaust muffler disposed on an outer side of a rear wheel so as to overlap the rear wheel when viewed from a side a muffler protector which covers the muffler. The muffler protector includes an inner protector half body covering the exhaust muffler from the rear wheel side and an outer protector half body covering the exhaust muffler from a vehicle outer side opposite to the rear wheel The inner protector half body is detachably mounted on the exhaust muffler or the outer protector half body while maintaining a state in which the outer protector half body is mounted on the exhaust muffler.

A clamp for use in joining conduit segments comprising a ring sector and a radially projecting channel sector having first and second straps, first and second compression members, a central compression member, and a fastener wherein upon tightening the fastener, axial forces along the fastener are transferred into clamping forces around the clamp in order to seal the conduit segments.

An improved venting and/or air admission valve for an operating fluid reservoir, wherein different shutoff levels (SOH) can be achieved. The venting and/or air admission valve is distinguished by the fact that it comprises an adapter, which can be fastened on an operating fluid reservoir wall, and that a valve housing of the venting and/or air admission valve can be fastened on the adapter in such a way that the adapter is arranged between the operating fluid reservoir wall and the valve housing.

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 exhaust tailpipe/emissions filter employs a reusable/replaceable insert and is configured to slide into and/or onto the exhaust tailpipe of the automobile to reduce air pollution.

A clamping assembly configured for an exhaust system of a vehicle may include a gasket engaged to be prevented from deviating using a method in which a pin is inserted into and engaged with a pin hole at an inlet pipe flange of a catalytic converter, wherein an outlet pipe flange of a turbocharger and an inlet pipe flange of the catalytic converter are clamped by a clamp by interposing the gasket between the outlet pipe flange of the turbocharger and the inlet pipe flange of the catalytic converter.
