There is described a component of an exhaust system for an internal combustion engine, which includes a wall in which at least one opening is provided. A perforated cover (16) at least partly closes the opening, wherein the cover (16) is mounted on the wall by means of a holder (18), and a portion (32, 34) of the cover (16) engages into an opening (28, 30) provided on the holder (18). There is also presented an exhaust system comprising such a component, and a method for manufacturing such a component, in which the cover (16) is mounted on the holder (18) by introducing at least one portion (32, 34) of the cover (16) into an opening (28, 30) provided on the holder (18).

An exhaust manifold is provided comprising a first log comprising a plurality of inlet segments each having a pair of inlet ports configured to receive exhaust gas from a pair of cylinders of an engine, a second log comprising a plurality of inlet segments each having a pair of inlet ports configured to receive exhaust gas from a pair of cylinders of the engine, and a collector coupled to the logs, the collector comprising a first pair of intake openings configured to receive exhaust gas from the first log, a second pair of intake openings configured to receive exhaust gas from the second log and an outlet configured to route the exhaust gas to a turbocharger, wherein the first pair of intake openings are coupled to a pair of bellows of the first log, each of the pair of bellows being coupled to an inlet segment.

An exhaust pipe support member of a vehicle includes: an elastic support portion that has multiple insertion holes into which multiple hanger stays provided in an exhaust pipe are inserted; a metal frame that surrounds the elastic support portion; and multiple support legs that are arranged between the elastic support portion and the metal frame to support the elastic support portion.

An exhaust device incorporated in a vehicle for travel on uneven terrains. The exhaust device includes an air blowing device and an exhaust pipe through which exhaust gas generated in a prime mover is directed out of the vehicle. The exhaust pipe includes an upstream pipe, a downstream pipe, and a joint device joining the upstream pipe to the downstream pipe in a manner permitting the upstream pipe to move relative to the downstream pipe, the air blowing device being disposed to blow cooling air toward the joint device.

Provided are a method for determining the disposition position of a spherical joint for coupling exhaust pipes to each other in an exhaust system, and an exhaust system, which enable engine vibrations to be more effectively damped. Inthepresent invention, strain gauges are attached at a plurality of locations in an exhaust system (1), simulated vibrations which simulate engine vibrations are imparted to the upstream-side end of the exhaust system (1), and bending strain is measured at each strain gauge. On the basis of the bending strain measured at each strain gauge, detected is a position at which generated is a bending moment that is equal to or greater than or equal to a torque amount which generates a maximum static friction force between a spherical inner-circumferential surface (26) and a spherical outer-circumferential surface (27) of a spherical joint (2) which come into contact with each other, and the detected position is determined to be the disposition position for the spherical joint (2).

Exhaust systems and passenger service vehicles, for example, buses are used together. The exhaust system can be arranged, in use, to be above an engine compartment. The exhaust system includes a first filter and a second filter, each filter having an inlet and an outlet. The inlets are inline with the respective first and second filters, and the outlets are transversely arranged with reference to the respective filters. Vehicles may have an overall length of about 35 feet or less and have an unladen weight of around 25,000 lbs or less.

A bulldozer includes a blade, an engine, first and second exhaust treatment devices that treat exhaust from the engine, and an engine cover. The first exhaust treatment device is disposed in front of the engine and lower than a first upper surface of the engine. The second exhaust treatment device is disposed above the engine. The engine cover includes a second upper surface sloping forward and downward. The engine cover covers the engine and the first and second exhaust treatment devices. Longitudinal directions of the first and second exhaust treatment devices extend along a vehicle lateral direction. In a top view of the bulldozer, the second exhaust treatment device includes a portion overlapping the engine. As seen from a side of the bulldozer, a front edge of the second exhaust treatment device is positioned forward of a rear edge of the first exhaust treatment device.

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.
