Abstract:
An integrated intake manifold-fuel rail construction with a separately molded trough-shaped fuel rail component friction welded to a runner spanning mounting plate molded as a part of the manifold. A filter is installed within the fuel rail component to intercept particles generated by the friction welding process to prevent their entry into the fuel injectors, each having one end installed in one of a series of sockets formed in the fuel rail component.
Abstract:
A process for producing an intake manifold having a main pipe made of wrought aluminum material and having an open end, a closed end opposite to the open end, a plurality of holes formed in its peripheral wall and outward tubular projections integral with the peripheral wall and each formed around each of the holes, and a plurality of branch pipes made of wrought aluminum material and each having one end fitting in and joined to each of the tubular projections. The manifold is smooth-surfaced in its interior, diminished in resistance to air and improved in air intake efficiency. The manifold requires no finishing procedure unlike those prepared by casting.
Abstract:
Systems and methods for directing and controlling air flow into an internal combustion engine are presented. In one example, an aluminum cylinder with two welded bearing holders is over molded with a short fiber reinforced polymer composite throttle body housing. The short fiber reinforced polymer composite throttle body housing may be welded to an engine intake manifold or it may be part of the engine intake manifold.
Abstract:
To provide a compact intake manifold which can easily and reliably hold the flame arrester (25) to the base member, the base member (21) having the flame arrester (25) incorporated therein has the recessed body portion (31) and the annular fitting holding portion (32) for fitting the flame arrester (25) in the axial direction. The fitting holding portion (32) includes an abutment surface (32a) and a fitting inner wall peripheral surface (32b). The flame arrester (25) includes a flame suppressing structure (26), an outer cylinder body (27) surrounding the flame suppression structure (26), and an elastic holder member (51) which covers the outer peripheral surface and both end faces of the outer cylindrical body (27). The elastic holder member (51) has an outer peripheral fitting portion (52) fitted to the fitting holding portion (32) while being held in close contact with the outer cylindrical body (27).
Abstract:
An air intake tract with a hydrocarbon adsorber is provided for adsorbing hydrocarbons of a motor vehicle. The hydrocarbon adsorber includes at least one first layer constructed of a hydrocarbon adsorbing material. Optionally, one or more stacked layers are provided including at least an uppermost layer and at least one intermediate layer. The at least one first layer includes a solid shape within an outer boundary and is adapted for sonic welding onto an interior of the air intake tract. The uppermost layer and any intermediate layers include an opening such that the uppermost layer provides access for a sonic welding tool from an upper side of the subassembly to the at least one first layer through the opening.
Abstract:
An intake apparatus for an internal combustion engine includes an intake apparatus body including a plurality of intake pipes which are connected to respective cylinders of the internal combustion engine, the internal combustion engine including the cylinders of which the number is multiples of three, and an outside gas distribution portion distributing outside gas to each of the plurality of intake pipes, the outside gas distribution portion including a single first outside gas distribution pipe connected to an outside gas supply source, a plurality of second outside gas distribution pipes branched from the first outside gas distribution portion, an outside gas collective passage gathering outside gas from the plurality of second outside gas distribution pipes, and three third outside gas distribution pipes branched from the outside gas collective passage and connected to the plurality of intake pipes respectively.
Abstract:
An air intake apparatus includes an air intake apparatus body including a surge tank, a valve body rotatably attached to the surge tank and configured to rotate between an open position and a closed position to open and close a fluid passage formed at a partition wall dividing an inside of the surge tank into two parts, the valve body being out of contact with the partition wall at the open position and being in contact with the partition wall at the closed position, the air intake apparatus body being formed by a first member to which the valve body is attached and a second member joined to each other, and the first member including a jig-receiving portion arranged in a vicinity of the fluid passage and configured to receive a jig holding the first member when the first member and the second member are being joined to each other.
Abstract:
An intake device includes: an intake port; a valve body which is disposed in the intake port and rotated around a rotating shaft between an opening position and a closing position; and a seal surface which is integrally provided at the intake port and made up of an inner wall surface with which the valve body comes into contact at the closing position of the valve body, wherein the seal surface includes a first seal surface having an inner contact portion which protrudes to the inside of the intake port and a first outer contact portion which is located further to the outside than the inner contact portion, and a second seal surface having a second outer contact portion without having the inner contact portion.

Abstract:
A valve casing of a flow regulating valve is welded to an end of a downstream section of a manifold body. Two passages are formed in the valve casing of the flow regulating valve. The valve casing accommodates a valve plate for switching at least one of the passages selectively between an open state and a closed state. A joint portion between the manifold body and the valve casing has height difference such that the portion in the vicinity of the passage corresponding to the valve plate is located at a position higher than the portion in the vicinity of the other one of the passages.
