Abstract: A rotary valve assembly includes a housing for positioning on an engine of the piston and cylinder type. The housing includes an intake passage for conducting a working fluid to the cylinder and an exhaust passage for conducting the working fluid from the cylinder. The housing has an internal cavity which intercepts the intake and exhaust passages, which cavity contains a rotary valve member having a window. The window is so positioned that when the member is rotated, it opens and closes the intake and exhaust passages in a periodic manner. The valve assembly may also include a throttle member mounted in the housing parallel to the rotary valve member. The throttle member has a hole which may be positioned opposite the intake passage. The throttle member is movable relative to the axis of the rotary valve member between a first position which places the hole in the throttle means opposite a first portion of the valve member and a second position which places that hole opposite a second portion of the valve member so that when the valve member is rotated, the open time of the intake passage can be controlled by the position of the throttle member. In some applications, the rotary valve member itself can function as the throttle member. A plurality of similar valve assemblies can be positioned adjacent to one another and concatenated so that they all operate in unison to control the working fluid flow to and from all the cylinders of a multi-cylinder engine. The assembly is particularly suitable for converting an internal combustion engine so that it operates under steam power. Other applications for the assembly are also disclosed.

Abstract: A variable camshaft timing system for an internal combustion engine varies the relative angular position between the intake camshaft and the exhaust camshaft by controlling the path of the timing belt. First and second idler arms, each having an idler wheel connected thereto, are independently pivoted around a common pivot point by means of a pair of positioning cams operatively connected to an electric stepping motor. The motor is controlled from an electronic control unit which receives signals indicating the engine operating characteristics and through a look-up table steps the positioning cams which in turn pivots the idler arms to rotate the intake camshaft relative to the exhaust camshaft thereby changing the intake valve timing.

Abstract: A valve assembly for use in internal combustion engine applications, of the type designed to regulate air-fuel mixture from a carburetor or other fuel injection means entering the cylinders of either two stroke cycle or four stroke cycle spark ignition engines to improve the part-load and full-load fuel efficiency of such engines by minimizing the pumping losses. This increase in efficiency is accomplished by regulating engine power output by employing time-duration-modulation control instead of the throttled or resistive intake control which is empolyed in the engines of the prior art. A rotary valve structure employs a tubular multi-port member comprising a rotary valve, with an outlet for each cylinder, operating at 15 p.s.i. maximum differential pressure and relatively low temperatures, connected in series with presently used poppet or reed or port type intake valves. Rotary valve timing or phase control is accomplished with a multi-pulley belt drive system.The time-duration-control limits engine output by matching the effective compression ratio to that ratio required to meet the demand placed on the engine in less than full load conditions. An adjustable full load stop prevents the engine from reaching its full load output, thereby allowing the effective compression ratio to be affected by the inventive valve structure throughout the entire range of engine opertion. Since the novel valve assembly allows unlimited reduction of the effective compression ratio, the engine manufacturer may reduce clearance volumes and hence increase the engine expansion ratio independently of any effect on the effective compression ratio of the engine.

Abstract: A method and apparatus for controlling the air flow in an internal-combustion engine that comprises an unthrottled variable-timing third valve engine modification. An unthrottled full charge of air is drawn into the cylinders during the standard intake stroke of a four-stroke internal-combustion engine. During the initial portion of the succeeding compression stroke, a portion of that full charge is discharged through a third valve. Thus, the same mass of air that would result from throttled engine remains in the cylinders to be compressed. This air quantity is adjusted by means of adjusting the timing of the opening and closing of the third valve in accordance with the power requirements of the engine. A full charge of air is utilized for a full load, while a lesser charge is utilized for a partial load. Power losses which result from conventional intake air throttling are thereby eliminated.
