Abstract: A rotary valve assembly will be utilized on internal combustion engines for regulating air-fuel mixture from a carburetor or other fuel injection system entering the cylinders of either two stroke or four stroke spark ignition engines serving to improve the part-load fuel efficiency of such engines by minimizing the pumping losses. This increase in efficiency is accomplished by substituting what is termed "time-duration-modulation" control for the present day "throttled" or "resistive" intake control now used to regulate engine power output. The rotary valve structure employs a hollow, or open sleeve, or tubular multi-port structure comprising the rotary valve, with an outlet for each cylinder, operating at fifteen (15) p.s.i. maximum differential pressure and relatively low temperatures, connected in series with presently used poppet or port type intake valves. Rotary valve timing or phase control is accomplished with a multi-pulley belt drive system.

Abstract: A phase shift mechanism including a plate carrying a pair of oppositely disposed idler sprockets, the plate being pivotally mounted on the crankshaft of an internal combustion engine so that the idler sprockets engage the timing chain at opposite points of its internal periphery and may adjustably control the position of the chain relative to the camshaft and crankshaft by the pivotal movement of the plate on the crankshaft thus effecting phase shifting between the two shafts and changing valve timing relative to piston position.

Abstract: The valve opening/closing timing control device includes: a driving rotating body; a driven rotating body; a fixed shaft portion; a fluid pressure chamber; a partitioning portion; and a phase control unit for controlling a rotation phase by supplying/discharging pressurized fluid to/from an advancing chamber or a retarding chamber via an inside of the fixed shaft portion. The driven rotating body has: an inner circumferential member with a cylindrical portion, and a coupling plate portion of the camshaft, the cylindrical portion and the coupling plate portion being integrated with each other; and an outer circumferential member provided with the partitioning portion. The outer circumferential member includes the inner circumferential member in a unified manner so as to have the same rotational axis. The inner circumferential member is formed with an iron-based material. The outer circumferential member is formed with a material that is lighter in weight than the iron-based material.

Abstract: An internal combustion engine includes a crankshaft rotatable about a crankshaft axis; a camshaft rotatable by the crankshaft about a camshaft axis; an engine cover defining an engine cover volume within the internal combustion engine; a drive member disposed within the engine cover volume which transfers rotational motion from the crankshaft to the camshaft; a camshaft phaser disposed within the engine cover volume which controllably varies the phase relationship between the crankshaft and the camshaft; an actuator which operates the camshaft phaser; and an actuator mount within the engine cover volume which mounts the actuator structurally independent of the engine cover, thereby allowing removal of the engine cover independently of the actuator.

Abstract: In accordance with the invention, an internal combustion engine having reciprocating piston sleeves is realized comprising an engine block with a pair of cylinders, each cylinder having an intake port, an exhaust port and two linearly opposing pistons connected to two opposing crankshafts. A pair of piston sleeves are reciprocatingly mounted in each cylinder, one piston sleeve around each piston. Each piston sleeve is connected to one of two eccentric shafts that run parallel and adjacent to each crankshaft. The piston sleeves have ported slots in communication with either the intake ports or the exhaust ports of each cylinder. The eccentric shafts are mechanically connected to the crankshafts such that they move in unison.
