Abstract:
An intake manifold for an internal combustion engine including a manifold base portion and a manifold cover portion. The manifold cover portion and base portion are each formed from a thermoplastic composite material. The base portion includes several runners which may be coupled to respective intake ports of an internal combustion head. The manifold base portion and the manifold cover portion may be selected from a group of differing parts to provide a manifold having desired application or performance characteristics.
Abstract:
An internal combustion engine recessed manifold entry reducing internal/external merge intake collector structure and working process for two and four-barrel carburetor and fuel-injection throttle-body throttles and manifolds. Normally located between the carburetor/throttle-body and the engine intake manifold, this device's design has recessed internal/external merged-bore passages that extend into the intake manifold entry area. Lowering the flow passages into the manifold plenum provides the opportunity to have their passages channel reverse runner flow away from the entry air throttles. This is accomplished by externally merging the multiple throttles' flow passages together so that they can be lowered to extend below the manifold mating flange surface. These changes allow more flow efficient performance tuning that deliver higher specific output power while making more efficient use of the air and fuel being consumed by the engine. They result in greater torque, horsepower, acceleration response, and smoother more reliable and consistent performance with less wear. These are done to make the engine's cylinders more stable and efficient.
Abstract:
A reed valve assembly is provided with a body, at least one flexible member, and at least one rigid member. Preferably, the at least one flexible member has a periphery so as to substantially cover opening(s) in the body when positioned adjacent to the body, and the at least one rigid member has a periphery so as to limit deformation of the at least one flexible member.
Abstract:
A fuel injector adapter for providing nitrous oxide to an internal combustion engine is disclosed. The nozzle has a central fuel injector passage that terminates at a first outlet end. Fuel from a fuel injector may be passed through the central fuel injector passage. The nozzle also has an inner annular passage arranged circumferentially around the central fuel injector passage. The inner annular passage terminates at a second outlet end. The nozzle also has an outer annular passage arranged circumferentially around the inner annular passage that terminates at a third outlet end. One or both of the inner and outer annular passages is adapted to pass nitrous oxide through it. The nozzle is adapted to fit between a fuel injector and an engine without substantial modification to the engine.

Abstract:
An intake manifold for a combustion engine is provided. The intake manifold has a body with a front end, a back end, a top and a bottom. The bottom has a first angled portion, a second angled portion and a horizontal portion located therebetween. The intake manifold further has a front end plate and a back end plate connected to respective ends of the body. The top plate has at least one opening for connecting at least one carburetor system to the intake manifold. The intake manifold further has a first and a second engine mounting plate and a plurality of straight tubes each having a first and a second end. The straight tubes are connected at their first end to the body of the intake manifold and at their second end to the engine mounting plates. The plurality of straight tubes are preferably extruded metal. A method for manufacturing an intake manifold for a combustion engine is also provided having the steps of extruding a body, machining a first and second engine mounting plate, a front end plate, a back end plate and a top plate, connecting the front, back and top plates to the body, extruding a plurality of straight tubes and welding the tubes to the body and to the engine mounting plates.
Abstract:
An air intake system for a fuel injection engine having cylinders equipped with a swirl port and a conventional straight port. The air intake system comprises a swirl control valve for opening or closing the inlet air passage to the straight port, and further comprises an adapter piece installed in the division wall separating the inlet air passages into the swirl port and the straight port. An aperture communicating both inlet air passages is formed in the adapter piece, and the size thereof is optimized in consideration of the size of an air induction hole disposed in the swirl control valve, to thereby obtain a larger operation area of the air fuel ratio of the lean air fuel mixture supplied to the engine.
Abstract:
A manifold for a multi-cylinder internal combustion engine including a hollow manifold casing having an air inlet connection and a barrier plate on one side thereof provided with ports aligned with the intake passages of the engine, the manifold being mounted on the engine block or cylinder head with the barrier plate spaced from the head or block to enable an insulating barrier of air to be maintained between the barrier plate of the manifold and engine for reducing the transfer of heat from the engine to the air admitted into the engine cylinders, and openings through the baffle plate allowing air to flow from the passageway to the ports.
Abstract:
A coupling system for attaching a first part to a second part using a locator and expansion shear pin is disclosed. The first part has a first flange and may be a formed part, such as an intake manifold. The second part has a second flange and may be a component, such as a throttle body, for attachment to the first part. The component includes a fastener-passing bore having an inner diameter. The locator and expansion shear pin extends perpendicularly from the first flange. The pin includes an expansion wall extending beyond the surface of the flange. A fastener-receiving bore is formed concentrically in the pin relative to the wall. The wall is expandable from a first diameter to a second diameter. The first diameter is less than the inner diameter of the fastener-passing bore. The second diameter is at least equal to the inner diameter of the fastener-passing bore.
Abstract:
A tube for directing fluid along a path that includes a bend. The tube comprising a conduit having a first aperture, a second aperture, and a bend portion adjacent the second aperture. An outer bend surface is integrally formed as part of the conduit to at least partially define the second aperture. An insert includes at least a portion of an inner bend surface and is disposed at least partially within the second aperture such that the outer bend surface and the inner bend surface cooperate to at least partially define the bend.
