A repair boot for an air intake assembly having an air intake duct. The repair boot is open between its ends and has a collar with a first interior dimension that is selected to complement the air intake duct and a second interior diameter that is selected to engage a surrounding flange on the exterior of air intake duct.

A plurality of parts that constitute an intake passage connected with an intake port of an engine include a constriction part that has a protrusion formed to protrude on an inner circumferential surface side of the intake passage. The constriction part includes cylindrical connections disposed on both sides of a constriction path in which the protrusion is formed. The constriction path has an outer circumferential surface recessed inwardly in a radial direction so as to follow a shape of the protrusion. A portion recessed most of the recessed outer circumferential surface is disposed inside inner circumferential surfaces of the connections in the radial direction. The constriction path has a uniform wall thickness. The constriction part is connected upstream of the throttle body.

The disclosure provides an air/exhaust system for a vehicle, including a vented exhaust outlet with an inner tube and an outer tube having vents that draw air into a gap between the tubes to mix with exhaust from the inner tube and discharge cooled exhaust, an exhaust shield for reducing the noise emanating from the exhaust pipe, an exhaust collector with an inlet body, a neck body that causes the flow of the exhaust to converge and an expansion cone defining an expansion angle that improves distribution of exhaust flow across a catalytic converter. The catalytic converter has an inlet matrix brick formed from a foil that is thicker than a foil used to form an outlet matrix brick to improve the durability and performance. Finally, the system includes an intake duct with an interface having fingers that contact a frame member to inhibit wear of the intake duct.

[Means for solving problem] The resin composition of the present invention comprises 100 parts by mass of a specific ethylene/-olefin/non-conjugated polyene copolymer (A) and 0.1 to 5 parts by mass of a peroxide (B), and the copolymer (A) comprises structural units derived from ethylene (a1), an -olefin (a2) having 3 to 20 carbon atoms, and a non-conjugated polyene (a3) including intramolecularly two or more partial structures in total selected from the group consisting of structures represented by the following formulae (I) and (II),

[Effect] The resin composition of the present invention is excellent in crosslinking properties and the resin composition and its crosslinked shaped article of the present invention can be used, without any limitation, in various applications known as applications of rubber composition, and can be suitably used, for example, for interior and exterior parts for automobiles and applications requiring heat resistance.

Air pipe for the intake tract of an internal combustion engine, for example a turbo engine, including a first pipe component composed of a first material and a second pipe component composed of a second material, the first material being more flexible than the second material.

An intake apparatus includes: an air cleaner unit purifying air sucked from a suction port and discharge the air from a discharge port; a junction pipe section having a plurality of inlet ports while having a single outlet port, each of the inlet ports being connected to the discharge port of the air cleaner unit; a tapered pipe section connected to the outlet port of the junction pipe section and having an inner diameter gradually decreased toward a downstream; a straight pipe section connected to a downstream side of the tapered pipe section and having a constant inner diameter; and an air meter provided in the straight pipe section.

An adaptive air intake joint for an internal combustion engine comprising a molded elastomeric duct body having standing ribs constructed and arranged to provide a continuous and sufficient contact force across the face of a joint of an adjoining duct body. A clamp secured to the duct causes the ribs to provide a continuous and sufficient contact force across a seal surface, eliminating the need for constant tension clamp and improving the air intake joint seal to prevent leakage that is especially common in cold environments.

A resin composition for intake hoses is provided. The resin composition includes a predetermined amount of polyester elastomer incorporated into a polyamide resin and a polypropylene resin and further includes an antioxidant, a heat stabilizer, a lubricant and a master batch if necessary, thereby exhibiting excellent durability, heat resistance, elongation, mechanical rigidity, pressure resistance and cold resistance, and reducing weight and production costs.

A flexible porous non-pollutive tube, wherein the walls of the tube are made by tapes formed by interlaced textile fibers, and to which activated charcoal is added, in agglomerate, powder or granulated form, and the textile tapes being wound over the charcoal and glued among the charcoal in the helical direction, forming an air conducting acoustic flexible helical pipe which is a part of a combustion engine's intake system used by the automobile industry, and adding the activated charcoal in the walls or in the pipe's external or internal lining.

A fresh air system for an internal combustion engine may include an inlet section, an air filter and a connecting section fluidly connecting the inlet section to the air filter. The air filter may include a filter element arranged in a filter housing, and a housing cover closing the filter housing and configured to be removable from the filter housing to change the filter element. The connecting section may be movably connected to the inlet section on an inlet side and detachably connected to the housing cover on an outlet side. To change the filter element when the inlet section is connected to the connecting section, the connecting section may be detachable from the housing cover and adjustable relative to the filter housing to such an extent that the housing cover can be removed from the filter housing.
