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.

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.

A filter arrangement may include a filter element and a gasket element. The gasket element may include a substantially circular flow-through opening and a locking collar. The locking collar may be arranged along a circumference of the flow-through opening with respect to a circumferential direction. The locking collar may form a hollow cylindrical installation space. The filter element may include a filter element body and a substantially hollow-cylindrical counter locking collar. The counter locking collar may include an open axial side and a covered axial side which may be spaced apart from each other with respect to an axial axis. The covered axial side of the counter locking collar may be covered by said filter element body. The counter locking collar may be at least partially inserted into the hollow cylindrical installation space of the locking collar.

A replacement kit enables a user to generate a desired audible sound from an exhaust system of a motor vehicle. The kit includes a replacement catalytic converter arranged to replace the vehicle's original equipment catalytic converter. The replacement catalytic converter is connected to the vehicle's factory muffler through a replacement pipe segment to obtain a more desirable, yet muffled engine sound. The factory muffler may be removed from the motor vehicle and the replacement catalytic converter may instead be connected to a muffler bypass pipe or pipes or replacement exhaust components/segments which channels the exhaust flow directly to the atmosphere to obtain a more powerful unmuffled exciting visceral sports car engine sound.

A vehicle exhaust evacuation system includes an adapter secured to an end of a vehicle tailpipe and a nozzle assembly secured to the end of a flexible hose for carrying vehicle exhaust outside of a building. The nozzle assembly has an aluminum cartridge removably secured in a rubber boot. Magnet assemblies are secured to the aluminum cartridge. Openings in the adapter allow ambient air to flow over the magnet assemblies to lengthen the life of the magnets.

A sensor table mounting system includes an insulating blanket assembly and a senor table. The insulating blanket assembly is configured to surround an external housing surface of an exhaust aftertreatment component housing. The insulating blanket assembly includes an inner blanket surface, an outer blanket surface, and a first restraint. The outer blanket surface is opposite the inner blanket surface. The first restraint includes a first restraint first end that is fixed to the outer blanket surface. The sensor table includes a platform, a first standoff, a second standoff, a first footing, and a second footing. The first footing is offset from the platform by the first standoff and configured to be coupled to the first restraint. The second footing is offset from the platform by the second standoff and configured to be coupled to the first restraint.

A muffler filter includes a housing including an aperture, a cartridge holder, at least one activated filter, an attachable lock associated with the activated filter, and a plurality of clamps. The muffler filter is configured to be securely affixed to a muffler of a vehicle allowing the activated filter to sieve noxious fumes from emissions from the muffler.

A replacement kit for use with a motor vehicle that was originally equipped with an exhaust system including an exhaust manifold and a catalytic converter welded thereto. The replacement kit includes a replacement catalytic converter arranged for use during use of the motor vehicle on public roads. Rather than welding, the replacement catalytic converter attaches to the exhaust manifold using a clamp to form a gas-tight seal. The clamp is arranged to move from the closed position to an open position to enable disengagement of the replacement catalytic converter from the exhaust manifold and substitution of a bypass pipe in place of the replacement catalytic converter to increase performance characteristics of the vehicle during off-road use.

A mixer, an exhaust aftertreatment component, an exhaust aftertreatment system and a vehicle in which the mixer comprises: an inlet cover, providing an inlet space; an outlet cover, providing an outlet space; and a connecting pipe part, comprising a gas inlet inside the inlet space, a gas outlet inside the outlet space, and an injection inlet; wherein the connecting pipe part comprises a conical section and a pipe section connected downstream to the conical section, the conical section is located inside the inlet space, a side wall of the conical section comprises a plurality of openings distributed along a circumferential direction, the gas inlet comprises the plurality of openings, and a swirling structure is provided on the plurality of openings.

A vehicle exhaust evacuation system includes an adapter secured to an end of a vehicle tailpipe and a nozzle assembly secured to the end of a flexible hose for carrying vehicle exhaust outside of a building. The nozzle assembly has an aluminum cartridge removably secured in a rubber boot. Magnet assemblies are secured to the aluminum cartridge. Openings in the adapter allow ambient air to flow over the magnet assemblies to lengthen the life of the magnets.
