Abstract:
A fuel injector adapter for providing nitrous oxide to an internal combustion engine is disclosed. The nozzle has a fuel injector passage, having a central axis and terminating at an injector outlet, for passing fuel from a fuel injector to an engine. The nozzle also has one or more first auxiliary passages, which may be arranged in an annular pattern around the fuel injector passage, and which terminate at first outlets. The nozzle furthermore may have one or more second auxiliary passages, which also may be arranged in an annular pattern around the fuel injector passage, and which terminate at second outlets. The first auxiliary passages and second auxiliary passages are adapted to supply nitrous oxide or other additional combustion reactants to the engine. The nozzle may be attached to an engine intake and may be adapted to fit between a fuel injector and an engine without substantial modification to the engine.
Abstract:
A carrier for mounting to an internal combustion engine having an intake manifold port, a fuel injector and a cylinder head port extending from a cylinder head. The carrier includes a central portion having an internal passageway for providing fuel to the fuel injector. An attachment portion extends from the central portion which is affixed between the cylinder head and the intake manifold ports. The carrier further includes a sleeve extending from the central portion for receiving the fuel injector, which is sealed by the sleeve and an O-ring. The fuel injector, port seals, injector O-ring, wiring harness, connector and fuel rail are integrated into a single carrier to provide sealing, electrical connectivity, and fuel delivery functions.
Abstract:
An intake pipe (10) for an internal combustion engine composed of shells (11a, 11b) in which the geometry of the joining surfaces (19) adopts an approximately stepped course in areas with a slight incline relative to to joining force (F). This produces areas with a greater or lesser inclination relative to a joint line (16) indicating the average inclination of the joining surfaces. This results in areas which can be welded with a high degree of stability because of their considerable incline towards the joining force. These areas can then support areas which are less inclined towards the joining force. This allows the shells (11a, 11b) to have strongly curved joining surfaces, which increases the geometric design freedom of the intake pipe and, in particular, makes it possible to manufacture intake pipes with strongly curved intake channels constructed from just two shells.
Abstract:
A resin intake manifold is provided with an integrally formed base member. The base member has a U-shaped curved distribution passage lower surface wall portion, an engine mounting flange portion formed in one end of the distribution passage lower surface wall portion, and a surge tank peripheral wall portion formed in another end and a lower surface side of the distribution passage lower surface wall portion. A resonator peripheral wall portion is integrally formed in a dead space in a lower surface side of the distribution passage lower surface wall portion and between the surge tank peripheral wall portion and the engine mounting flange portion. In accordance with the structure in which the wall itself constituting the resonator is formed by the structure member, it is possible to structure the resonator without enlarging a size of the intake manifold and without lowering the strength.

The present invention relates to an intake manifold or distributor for a thermal engine constituted by at least two parts (1, 1null) assembled together, in particular two parts made from thermoplastic material assembled by vibration welding and comprising an intake or plenum chamber connected, for fluidic communication, to intake pipes opening into the chamber. Intake manifold or distributor for a thermal engine characterized in that it comprises an additional attached piece (4) comprised, on the one hand, of a main body forming a support and fitting plate and, on the other hand, of pipe portions (6, 6null) produced in one piece with said body (5) and defining at least the inlet orifices (6, 6null) of said pipes (3), said attached piece (4) being positioned and, if applicable, fixed, prior to assembly of said at least two parts (1, 1null) forming said manifold or distributor on or in one of these parts.
Abstract:
An opening long in the longitudinal direction of a duct wall is formed. The whole of the opening is covered with non-woven fabric, and the lateral width of the opening is set to be not shorter than {fraction (1/20)} of the circumferential length of the duct wall. Alternatively, a porous member is thermally welded with the head of an opening of a small cylindrical portion projecting from the duct wall of a duct body 1, while the duct body is prevented from deformation. In a method for manufacturing the air take duct, a high-melting molded piece is brought into contact with a hot plate so as to be heated. A low-melting molded piece is disposed at a distance from the hot plate so as to be heated by radiation heat from the hot plate.
