Abstract:
An intake manifold includes a plurality of intake pipes that are provided in line to send air to an engine mounted on a vehicle through the intake pipes. Each of the intake pipes includes a main body formed of resin and an end pipe formed of resin, welded to a lower stream end side of the main body, and joined to the engine. Further, one member of the main body and the end pipe is provided with a rib that is formed on a side surface portion of the one member and that extends toward a lateral side of the other member. The other member is provided with a restriction portion that is formed on a side surface portion of the other member and that interferes with the rib to restrict moving of the main body in the crash direction relative to the end pipe when a weld portion of the main body and the end pipe is broken due to a collision load applied to the intake pipe at a vehicle crash.
Abstract:
A family of manifolds for a family of engines. A first and second engine respectively have a first and second number of cylinders. The second number is at least one and smaller than the first number. Each manifold has a plenum chamber and an inlet. The first and second manifolds respectively have the first and second number of outlets, each connected to one of a first number of runner passages. The first manifold is manufactured by inserting an outlet insert for forming at least one of the first number of outlets into a first or second mold, forming a first portion thereof using the first mold, forming a second portion thereof using the second mold, and connecting the portions. The second manifold is manufactured by forming a first portion thereof using the first mold, forming a second portion thereof using the second mold, and connecting the portions.
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 manifold for an internal combustion engine comprises upper and lower shell members with outer flanges. The shell members define a manifold cavity having a plenum and a plurality of runners. The upper shell includes an upper post formed as an indentation into the plenum with a tunnel wall and a terminus wall. The lower shell includes a lower post formed as an indentation into the plenum with a tunnel wall and a terminus wall. The terminus walls are attached to provide a brace across the plenum. One of the posts includes an orifice penetrating the tunnel wall. A sealed coupler extends from the one post and is adapted to receive a secondary gas for mixing within the plenum. Thus, secondary gases can be introduced without additional structures that could impede gas flow and could increase manufacturing cost.
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.
Abstract:
A frictional weld joint couples together first and second body portions of an article. The first body portion has a first nominal wall thickness and a first joint surface. The second body portion has a second nominal wall thickness and a second joint surface. A total bead height is defined between the joint surfaces. A first bead extends from the first joint surface defining a first bead height. A second bead extends from the second joint surface and is coupled to the first bead. A final second bead height is defined between the first bead and the second joint surface. A ratio of the first bead height to the final second bead height is of from about 0.40 to about 1.70. A ratio of the total bead height to at least one of the first and second nominal wall thicknesses is equal to or less than 6.00.
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:
An air intake hose for a vehicle may include a blow molding portion formed in a hollow hose shape by blow molding, an injection molding portion formed in a hollow hose shape by injection molding, and a coupling portion formed at one end of the blow molding portion, wherein the blow molding portion and the injection molding portion may be coupled with each other by injecting a material forming the injection molding portion into an injection mold in a state in which the coupling portion may be inserted in the injection mold.
Abstract:
A composite material intake manifold cover includes braces integral to the outside surface of the cover to stiffen the cover and reduce noise and vibration associated with the cover. The cover has a flange around the periphery with a raised weld bead, the weld bead provided for welding the cover to a mating piece. The flange extends outwardly from the cover for a first distance over most of the periphery and a second distance to support the braces over the remainder of the periphery. The braces extend upwardly from the upper surface of the flange at the sections of the flange extending out the second distance and may be placed between adjacent intake runner ports. By providing portions of the flange extending out a greater distance, a more substantial brace can be supported, thereby improving the noise and vibration characteristics relative to conventional stiffening ribs.
Abstract:
Disclosed herein is an actuator for regulating the flow of fluids in first and second flow paths of an internal combustion engine. The actuator includes a motor having a rotatable drive shaft, a gear assembly driven by the drive shaft of the motor, and first and second output shafts rotated in opposite directions by the gear assembly. The first and second output shafts are operatively linked to valves in the first and second flow paths, respectively, to regulate the flow of fluids in the first and second flow paths.
