The disclosure provides a fixing device for connecting an exhaust system component to a vehicle body, including: a carrier for attachment to the vehicle body; and an elastomer element connected to the carrier. The elastomer element has a connection recess into which a widened end portion of a holding element of the exhaust system component can be inserted, such that a connection region of the elastomer element defining the connection recess at least partially undercuts the widened end portion of the holding element in a joining direction. A fixing device comprises a stiffening structure stiffening the connection region of the elastomer element to impede an extraction of the widened end portion of the holding element.

An exhaust mechanism includes an exhaust pipe, an exhaust port, and a baffle plate. The exhaust pipe has one end connected to an engine and another end opposite to the one end along a length of the exhaust pipe. The exhaust port is provided at another end of the exhaust pipe and extends in a first direction inclined from the height direction along a height of the work vehicle. A length of the exhaust port in the height direction is shorter than a length of the exhaust port in the transverse direction perpendicular to a plane including the first direction and the height direction. The baffle plate is provided in the exhaust port and configured to change an exhaust gas flow from the first direction to the transverse direction.

An exhaust system includes at least one exhaust gas purification component, at least one exhaust line, at least one connecting device for connecting the exhaust system to an internal combustion engine of a motor vehicle and at least one fastening element for additionally fastening the exhaust system to the motor vehicle. The purification component can oscillate at a first resonance frequency range of less than 150 Hz in a fastened state. The purification component can oscillate due to vibrations of the engine at least when the engine is started or switched off. This, in particular, allows ash residues to be removed from a purification component during starting of the motor vehicle, so that maintenance expense for the purification component is reduced and effective operation thereof is possible over the long term. A motor vehicle having an exhaust system and a method for operating the motor vehicle are also provided.

A dump truck includes: a main frame that extends in a front-back direction of a vehicle body; an engine installed on the main frame; an exhaust aftertreatment device that is supported by the main frame and purifies exhaust gas from the engine; and a communication pipe having a first end connected to the engine and a second end connected to the exhaust aftertreatment device, in which the exhaust gas discharged from the engine flows to the exhaust aftertreatment device. The communication pipe includes: an upstream pipe extending from the engine to a lateral side thereof; a bellows pipe angularly connected to the upstream pipe and extending in an up-down direction; and a downstream pipe angularly connected to the bellows pipe.

An exhaust system including: an exhaust pipe including a straight portion, and a bent portion that is bent and extends from a downstream end of the straight portion; a muffler provided on a downstream side of the exhaust pipe; and a reinforcing member, wherein: the straight portion of the exhaust pipe is connected with an upstream end of the muffler through the bent portion; and the reinforcing member is provided so as to extend across a downstream end portion of the straight portion, and an upstream end portion of the muffler.

An exhaust manifold includes an inner assembly that defines an exhaust gas passage and an outer housing assembly that surrounds the inner assembly. The outer housing assembly includes a first housing component configured for attachment to an engine and a second housing component configured for attachment to a turbocharger. The first and second housing components cooperate to surround the inner assembly. At least one fastener secures the first and second housing components together to generate a compressive force that seals and holds the inner assembly in a gas tight manner.

An exhaust system of a saddle-ride type vehicle includes an exhaust pipe portion, a chamber portion, and a silencer. The exhaust pipe portion is coupled to an engine supported by a frame. The exhaust pipe portion is configured to guide exhaust air. The chamber portion is coupled to the exhaust pipe portion. A cross section of the chamber portion is formed larger than the exhaust pipe portion. The silencer is coupled to the chamber portion. The chamber portion includes: a main body portion disposed below the frame, and a fixing bracket projecting upward from the main body portion. The fixing bracket is secured to the frame. The frame and the fixing bracket have a fixed position. The fixed position is positioned above a lower end of the frame.

An exhaust muffler for transverse installation in a vehicle includes a muffler housing (26) elongated in the direction of a housing longitudinal axis (G) with a housing jacket (28) and two front walls (30, 32). The two front walls (30, 32) are arranged at spaced locations from one another and define an interior (34) of the muffler with the housing jacket (28). At least one inlet pipe (36) leads into the interior (34) of the muffler and at least one outlet pipe (20) leads out of the interior (34) of the muffler. At least one front wall (30, 32) has at least one predetermined deformation area (50, 52).

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.

An exhaust line element includes an exhaust volume comprising a metal enclosure with a thickness smaller than 1 mm and at least one metal plate with a thickness comprised between 0.5 and 5 mm. The metal plate comprises a central part that does not contact the metal enclosure and between 2 and 4 fastening tabs are secured to the central part. Each fastening tab is spot and transparently welded to the metal enclosure.
