Abstract:
The invention addresses a challenge for providing an intake manifold that is able to suppress interference of the intake manifold with fuel injection valves at the time of a collision of a vehicle. In an intake manifold, joint faces and joint portions are connected to each other such that lines extended from the joint faces of flange portions and joint faces of the joint portions are oriented toward positions clear of fuel injection valves. In the intake manifold, each joint portion is formed such that a length of the joint face in a direction in which the joint face extends is longer than a maximum spaced distance between the corresponding fuel injection valve and the corresponding flange portion.
Abstract:
An intake manifold is adapted for use with an engine in a front wheel drive vehicle and a rear wheel drive vehicle, for example, with both a transversely mounted and longitudinally mounted engine. The intake manifold is modular and includes a plenum body defining a first port and a second port. A series of runners are adapted to connect to the plenum body. A throttle body connector is adapted to connect to the first port and the second port based on the engine positioning in the vehicle. An end plate is adapted to connect to the first port and the second port.

Abstract:
A resonator for a vehicle, which reduces intake noise by using a resonance chamber for frequency tuning, includes an outer pipe having a first outer pipe with an inlet for introducing external air and a second outer pipe with an outlet for discharging the air introduced into the inlet to outside, an inner pipe disposed inside the outer pipe and having a plurality of slits for giving a passage of air, and an expansion pipe inserted between the outer pipe and the inner pipe to partition a space between the outer pipe and the inner pipe into a plurality of spaces and thus partition the resonance chamber into a plurality of regions.
Abstract:
A frictional weld joint couples first and second body portions of an article together. The frictional weld joint comprises a first bead extending from the first body portion of the article and a second bead extending from the second body portion of the article. The second bead has an interior stem and an exterior stem space from the interior stem defining a cavity therebetween. The first and second beads are placed in contact with each other with the centerline of the second bead offset from the centerline of the first bead. A force is applied to either the first or second body portions to generate friction between the first and second beads to plastically displace the first and second beads. The force is removed for fusing the first and second beads together to couple together the first and the second body portions of the article.
Abstract:
A friction-weld interface device for improving a structural strength of an assembly includes a first component having a concave tapered surface. The friction-weld interface also includes a second component having a convex tapered surface that is complementary to and is configured to receive the concave tapered surface of the first component. The assembly is formed by friction welding the concave tapered surface to the convex tapered surface. The friction-weld interface device may be used to assemble an air-intake manifold for an internal combustion engine, wherein the air-intake manifold is at least partially joined by the process of friction welding.
Abstract:
An air intake control valve includes a body extending to divide an inner portion of a surge tank of a multi-cylinder internal combustion engine into two portions, the body serving as a divided surface to divide the inner portion of the surge tank into the two portions, a valve element operated to rotate for opening and closing a fluid passage formed at the body, and a seal member sealing between a sealed surface of the surge tank and an outer periphery of the body, the seal member including a seal portion constituted by two contact portions that make contact with the sealed surface in a state where the two contact portions extend in directions opposite from each other relative to the divided surface.
Abstract:
An intake manifold is disclosed which has an upper shell portion having a first peripheral flange, a lower shell portion having a second peripheral flange, and at least one metallic post having a first plate and a second plate. The first and second peripheral flanges are friction welded and the first plate of the posts is friction welded to the upper shell portion and the second plate of the posts is friction welded to the lower shell portion. The upper and lower shells are made of a polymeric, or plastic, material. The metallic post is comprised substantially of aluminum or other suitable metals or alloys. The upper and lower shell portions define a cavity and a section of the post between the first and second plates traverses through the cavity.
Abstract:
This invention relates to a double-plenum or double-chamber inlet manifold or splitter, made up of a structural unit comprising two distinct coupled plenums with a common wall, an inlet opening for each of the two plenums and several pipes through each of the said plenums, the said superimposed plenums having substantially flattened general structures and forming, with their respectively connected inlet openings and pipes, two independent circulation circuits running from the entrance at the inlet openings to the outlet at the external openings of the pipes, the said external or outlet openings of the pipes being grouped in pairs, with each pair having an opening of each of the two types of pipes; the manifold comprises two one-piece parts assembled together, in a gas-tight manner, at the continuous assembly areas, a first part incorporating at least the two inlet openings and first portions of the walls of the two plenums, contiguous to the said openings and the second part incorporating the pipes and second portions of the walls of the two plenums, contiguous to the said pipes and complementary to the above-mentioned first portions.
Abstract:
An engine intake manifold assembly (10), including a first component (12) having a first mating surface (14) and a second molded plastic component (16) having a second mating surface (18). The second molded plastic component (16) is adhesively bonded to the first component (12) with an adhesive (20).
