Abstract: An air intake assembly for a motorcycle provides increased air flow to the carburetor by increasing the intake area of the ducting and placing it out in the air stream facing forward so that a ram air effect is achieved. Increased intake area is provided by dual velocity stacks arranged in an over-and-under vertical orientation positioned directly adjacent the side of the engine to minimize the width of the motorcycle. A compact aesthetically-pleasing assembly is provided which can also increase performance.

Abstract: There is disclosed herein an improved air and fuel intake system for a high performance internal combustion engine for installing on a supercharger or the intake manifold of the engine. The air intake system is attached to the mounting surface of the supercharger or intake manifold such that the plurality of separate air passages of the intake system ensure the uniform distribution of intake air to all parts of the supercharger or intake manifold. Each air passage has a decreasing cross-sectional area along the direction of air flow to increase the velocity of the intake air. The air intake system includes a forwardly disposed air inlet, which faces in the direction of travel of a vehicle powered by the engine. The air passages are controlled by butterfly air valves in the air inlet.

Abstract: An acceleration fuel pump for use with a combustion engine carburetor is an integral part of the carburetor body and provides an additional flow of fuel to the fuel-and-air mixing passage of the carburetor during acceleration of the engine. The acceleration fuel pump has a plunger which inserts sealably into a cylindrical cavity carried by the body of the carburetor. During acceleration of the engine, the plunger inserts further into the cavity against the resilient force of a spring and toward a resilient check valve member causing the member to deform into a fuel feed state. A fuel passage which extends between the bottom of a fuel chamber of the carburetor and the fuel-and-air mixing passage of the carburetor is intersected by the cavity and the resilient check valve member.

Abstract: A wobble plate engine assembly incorporating as offset mount between the wobble plate and each connecting rod to a piston such that a line of action of the connecting rod at the wobble plate is resolved into a centripetal and tangential component thereby minimizing the component of applied forced directed through the wobble plate and maximizing the force the force applied along the wobble plate. The connections between the wobble plate, connecting rod and pistons incorporate spherical bearings. Also a wobble plate internal combustion engine incorporating the wobble plate engine assembly is presented.

Abstract: The reciprocating engine more particularly intended for high pressure applications or motor vehicle CO.sub.2 air conditioning systems, has a wobble plate transmission, whose wobble plate (3) can assume different inclined positions for power control purposes. For this purpose is provided a wobble joint constructed as a knuckle joint, allowing the tilting movement of the wobble plate (3) supported on the engine shaft (4) through a slot guide (11, 11') of a driving pin (9). A good controllability of the reciprocating engine results from friction-reducing engine components provided on the driving pin (9) and comprising bearings (32, 33), which allow a rotation of the driving pin (9) about its longitudinal axis, as well as a sliding bush or a roller bearing (47) on one of the pin ends (40, 43) engaging in slot guides (11, 11'). In addition, in the vicinity of the more strongly loaded pin end is provided an axial force-absorbing sliding disk (42).

Abstract: An opposed piston internal combustion engine includes a rotary shaft provided with a first and second swash plate, each inlined relative the axis of the shaft at equal but opposite inclinations. The shaft is mounted for rotation in a frame on which at least one cylinder is fixed in parallel alignment. A first set of pistons on the ends of a tubular post is fitted in the cylinder with a central rod extending coaxially through the post and the first piston set. A second set of pistons is then fixed to the ends of the rod. Both the rod and the post engage the respective swash plate peripheries, and are thus reciprocated in opposition as the shaft is turned. In this manner the gas mixture between the piston sets at one end is compressed while the mixture at the other end is ignited.

Abstract: An internal combustion engine having a crankcase with a crankshaft and cylinders radiating from the crankcase, where the cylinders are circumferentially spaced apart. There are eccentric cams on the crankshaft which contact reciprocating pistons to move them in turn outwardly from the crankshaft. Pressurized air forced into the cylinders moves the pistons inwardly. The pressurized air and fuel are ignited in the cylinder to continue the reciprocation of the piston. Rotary valve tubes with ports supply air to the cylinders. The air is pressurized by a ram air blower. Both the rotary valve tubes and ram air blower are connected to a gear system driven by the crankshaft.

Abstract: Apparatus for reduction of pollutant emissions by internal combustion engines includes a tapered, coaxial multiconical structure used as a gas separator. The gas separator is used to provide oxygen enriched air to an engine, thus providing a reduction in the amount of nitrogen provided thereto. The resulting exhaust gas includes fewer oxides of nitrogen, reduced quantities of hydrocarbons, and decreased percentages of carbon monoxide. Air is directed through the structure, entering at a wide mouth thereof. A fan may be provided for directing the air through the structure. The air exiting at the central portion of the narrow end of the structure, which has an increased ratio of oxygen to nitrogen, is directed by a conduit to the engine inlet. The structure is inexpensive, and easily mounted on existing engines, thus providing a retrofitting device for conforming older cars to current pollution standards.

Abstract: An air intake unit for an internal combustion engine, especially for installation in a zone of a roof of a driver's cab of a utility vehicle. The air intake unit includes an approximately square intake box having an inlet port located along a longitudinal side thereof. The inlet port is covered with a perforated plate and an air intake conduit is provided for leading to the internal combustion engine. The intake conduit is connected to an outlet port of the intake box on one end face thereof. And an air baffle is arranged in the intake box in an area of the outlet port for shielding the outlet port with respect to the inlet port. The air baffle is equipped with a plurality of perforations.

Abstract: An air diffuser is insertable within the intake opening of a carburetor air filter housing in order to separate and diffuse the air flow to the carburetor. The air diffuser includes a body portion insertable in the intake opening and a multiplicity of conduits or pipes having an inner end disposed within the body portion and an outer end extending into the airstream in advance of the housing. The inner end portions of the conduits are disposed in parallel relation while the outer end portions thereof extend angularly outward from the axis of parallelism.
