    摘要： A swinging power unit type motorcycle having an engine swingably hung and pivoted on a body frame, and a pair of plates forming a rear fork connected to the engine. A chain drive transmits power from the engine to a reduction gearbox which incorporates the rear wheel axle and is supported between the rear fork. Shock absorbers are connected between the body frame and the rear fork. The engine, rear fork, rear wheel axle, chain drive, and reduction gearbox are interconnected to swing as a unit relative to the body frame.

    摘要： A modular internal combustion engine is provided in which a single crankcase can be adapted to a plurality of different types of engine configurations. The crankcase is open at its top so that each upper side edge of the crankcase forms a mounting flange while a crankshaft is rotatably carried by the crankcase. Block members and adapter members are provided and each includes a mounting flange formed along each longitudinal side. All of the mounting flanges are substantially identical to each other so that any one mounting flange can be detachably secured to another mounting flange. Thus to construct the engine, one mounting flange of either the block or adapter member is attached to one crankcase mounting flange while one mounting flange on the other member is attached to the other crankcase mounting flange. In addition, the remaining mounting flanges on the block and adapter members register with each other and are secured together. At least one block member is utilized in each configuration and the block member is adapted to reciprocally carry at least one piston therein. The piston in turn is operatively coupled to the crankshaft to rotatably drive the crankshaft upon reciprocation of the piston in the conventional manner.

    摘要： An internal combustion engine having an arrangement for compensating for the pressure in the crankcase of the engine. The arrangement includes a control valve which is arranged so that it is exposed on the one hand to the pressure in the crankcase and on the other hand to the pressure prevailing in an operating chamber which is separate from the connection conduit between the crankcase and the suction pipe and communicates with the atmosphere through an auxiliary conduit.

    摘要： A solid state capacitor discharge ignition system for use in a single-cylinder engine having a magneto for an electrical energy source wherein the capacitor is discharged through a silicon controlled rectifier in response to trigger signals generated by a trigger assembly mounted on the rotor and stator of the magneto. The trigger assembly generates at least two discrete spaced pulses at running and cranking speeds, and the spacing between the two pulses corresponds to a desired shift in the engine timing between cranking and running speeds. The trigger assembly, the silicon controlled rectifier and the circuit connection therebetween are such that both pulses are applied to the controlled rectifier at all engine speeds; but the retarded ignition pulse is effective at cranking speeds and the advance pulse is effective at running speeds.
