An exhaust pipe flange with an exhaust gas pipe and with a flange plate fastened to the exhaust gas pipe, wherein the flange plate has an inner side which can be turned toward a cylinder head with a sealing surface which can be placed directly or indirectly against a cylinder head, and a seat in which the exhaust gas pipe is received. The exhaust gas pipe is joined to the flange plate and sealed in the region of the seat on the inner side by a welded connection.

A spherical annular seal member 38 is used in an exhaust pipe joint and includes a spherical annular base member 36 defined by a cylindrical inner surface 32, a partially convex spherical surface 33, large- and small-diameter side annular end faces 34 and 35 of the partially convex spherical surface 33, and an outer layer 37 formed integrally on the partially convex spherical surface 33 of the spherical annular base member 36. The spherical annular base member 36 includes a reinforcing member made from a metal wire net 5 and a heat-resistant material containing expanded graphite filling meshes of the metal wire net 5 of this reinforcing member and compressed in such a manner as to be formed integrally with this reinforcing member in mixed form. In the outer layer 37, the reinforcing member, the heat-resistant material, and the solid lubricant are integrated in mixed form.

The present disclosure relates to an all-terrain vehicle and an exhaust assembly for an all-terrain vehicle. The all-terrain vehicle includes: a frame, a V-type twin-cylinder engine and an exhaust assembly. The V-type twin-cylinder engine has a first exhaust port and a second exhaust port, and a cylinder corresponding to the first exhaust port is located in front of a cylinder corresponding to the second exhaust port. The V-type twin-cylinder engine is mounted on the frame. The exhaust pipe group has a first end coupled to the first exhaust port, a second end coupled to the second exhaust port, and a third end coupled to a pipe of the muffler. The exhaust pipe group is divided into at least two exhaust pipes, and adjacent exhaust pipes are flexibly coupled.

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.

The invention relates to an emissions control device for a combustion engine aftertreatment arrangement, the emissions control device comprising: a housing configured for accommodating an emissions control substrate; and at least one first opening in the housing, which at least one first opening is con figured for receiving a threaded assembling element, which threaded assembling element is configured for assembly of the emissions control device in a cavity of the aftertreatment arrangement. The emissions control device further comprises at least one second opening in the housing, wherein the at least one second opening is provided with a thread, configured for receiving a threaded disassembling element, which threaded disassembling element is configured for disassembly of the emissions control device from the cavity of the aftertreatment arrangement. The invention further relates to a combustion engine aftertreatment arrangement for a vehicle and a method for disassembling an emissions control device.

A flexible pipe element is provided formed as a metal bellows with at least one corrugated bellows section and a bellows brim, which forms one end of the metal bellows, and a connection element for connecting the metal bellows to a continuing pipe part or to a connector, with the connection element having a connection area for abutting a contact area of the bellows brim. An annular bulge is formed in the contact area of the bellows brim and/or in the connection area of the connection element projecting beyond an average level of the contact area and/or an average level of the connection area in order to form a linear seal between the contact area and the connection area. A method for producing such a flexible line part is also provided.

Heat recovery component for an exhaust gas system of an internal combustion engine, comprising an inlet, an outlet, a heat recovery branch conduit comprising a heat recovery branch conduit inlet, a heat recovery branch conduit outlet, and a heat exchanger arranged in the heat recovery branch conduit, a bypass branch conduit being separate from the heat recovery branch conduit, and a valve being configured to be rotatable between a heat recovery end position and a bypass end position, the valve being arranged to be rotatable around a rotation axis located in the bypass branch conduit, wherein the valve comprises a bypass valve flap and a heat recovery valve flap, the bypass valve flap and the heat recovery valve flap being operatively connected by a support.

A structure is provided for installing a pipe fixing clamp installed in a sound absorber. A part of a curved pipe portion of an internal structural pipe of the sound absorber is cut to form an exhaust gas flow space. The pipe fixing clamp having multiple holes is connected to the exhaust gas flow space.

A gasket retainer that is absent sharp corners, has apertures of reasonable dimensional tolerance, and may be conveniently made by a variety of manufacturing processes. The retainer is made from thin flat springy material that readily returns to form after slight bending. Representative gasket capturing apertures are of smoothly non-convex outline with major dimension sufficiently large to allow passage of a ring shaped gasket turned on edge and minor dimension sufficiently small to engage, on approximately opposite circular segments that each engage along less than one third of a gasket circumference, a cavity or groove on the outside diameter periphery of the gasket turned flat parallel to the retainer material sheet. Fasteners may be retained by similar apertures.

A shield for a diesel exhaust fluid injector is mounted horizontally in an opening in a side wall of an exhaust gas aftertreatment system of an internal combustion engine. The diesel exhaust fluid injector configured to inject diesel exhaust fluid in a direction generally normal to the side wall into a mixer positioned in an exhaust gas stream. The shield may include a first portion extending axially and a second portion extending radially inwardly from the first portion.
