Abstract: An internal combustion engine includes an engine block having one or more cylinders and a rotary disk valve mounted on top of the engine block. The rotary disk valve includes an intake passage for directing intake air into the cylinders and an exhaust passage for exhausting combustion gases from the cylinder. The center of the intake passage and exhaust passage are equidistant from the axis of rotation of the rotary valve. The intake passage and exhaust passage in the rotary valve communicate with each cylinder in succession as the valve rotates, allowing the use of a single valve to serve multiple cylinders. Both the intake passage and exhaust passage have a cross sectional area at its narrowest point equal to at least 40% of the cross sectional area of the cylinders.

Abstract: A two-way rotary manifold-selecting valve forming a combustion chamber for an internal combustion engine has a frusto-conical rotor nestingly residing in a housing having a frusto-conical passage communicating with the base of the housing. The housing has a pair of ports through the side, and the rotor has a side passage entering a portion of the slanting side of the rotor and exiting at the base of the rotor. The housing is open at the bottom, and may be affixed co-axially with a cylinder of a piston-type internal combustion engine so that the interior passage within the rotor forms the combustion volume of the cylinder. The small diameter ends of the housing passage and the rotor are disposed at the bottom of the assembly when so installed. A dry-lubricated refractory sealing assembly is emplaced around the rotor and extends outwardly therefrom to engage the inner housing surface, thus holding the rotor at a standoff distance. All wear is thus confined to the seal material and the housing wall.

In a preferred embodiment of the invention, a single rotary valve is associated with a plurality of combustion chambers for directing intake air into the combustion chambers and exhaust gases from the combustion chambers in succession as the valve rotates. Also, in a preferred embodiment of the invention, a spark plug and fuel injector are mounted on the rotary valve for injecting and igniting fuel in each combustion chamber.

Abstract: An internal combustion engine has rotary valves associated with movable shutters operable to vary the closing of intake air/fuel port sections to obtain peak volumetric efficiency over the entire range of speed of the engine. The shutters are moved automatically by a control mechanism that is responsive to the RPM of the engine. A foot-operated lever associated with the control mechanism is also used to move the shutters between their open and closed positions.

Abstract: An exhaust for an internal combustion engine includes an exhaust valve rotating within the cylinder block to communicate with successive cylinders. An exhaust conduit rotates with the valve and is of smaller diameter than the valve. Combustion products are initially exhausted thorugh the conduit to attain high velocity. Continued rotation of the valve closes the duct and directs combustion products through the valve. The conduit terminates within the valve to induce flow of gas through the valve.

Abstract: A four-stroke internal combustion piston engine includes at least two cylinders disposed in axial alignment opposite on another. Each cylinder has a piston axially reciprocal therein with the pistons in the two cylinders operating with a phase shift of 180.degree.. Each piston is connected by a piston rod to the same crankshaft located between the cylinders. Each piston moves between a bottom dead center at an inner end of the cylinder adjacent the crankshaft to a top dead center at an outer end of the cylinder spaced outwardly from the crankshaft. During movement of the piston from the inner end to the outer end, fresh air or a fuel-air mixture is drawn into the cylinder through a suction system and when the piston moves in the opposite direction a transfer system conveys the fresh air or fuel-air mixture into a combustion space formed between the outer end of the cylinder and the piston.

Such drivers alternately engage sliprings carried by the valve for incrementally rotating the valve in a single direction of rotation as the piston reciprocates. The valve has at least one recess for providing communication between intake and exhaust gas passages as it rotates. The central recess is C-shaped, so that the piston has a first portion including the recess, and a second portion having a flat piston face, the second portion being V-shaped.

Abstract: An internal combustion engine having banks of oppositely disposed cylinders is disclosed having a rotary valve for each bank which directs the flow to supply the inlet air and to dispose to the exhaust gases. Each of the rotary valves can be liquid cooled and is synchronized to time the inlet and exhaust gas to and from the proper cylinders. A fuel injection system provides the fuel to stratify its change. The fuel supply to any cylinder can be controlled or terminated during the low power requirement of the engine, such as when the engine is operating at reduced power or when the engine is idling. The engine can be built in any number of cylinders, but the four and eight cylinder combination makes for the most compact design.

Abstract: A rotary valve for an internal combustion engine is provided in the upper end of a cylinder to control intake and exhaust. A combustion chamber is formed in the valve and the valve is movable co-linearly with respect to the longitudinal axis of the cylinder under the control of a hydraulic fluid whereby the combustion forces on the valve are absorbed by the fluid and the valve can move in response to the pressures and vacuums in the cylinder. A special valve is provided for controlling the flow of the hydraulic fluid, and ducts are provided in the inlet and outlet ports with special seals engaging the rotary valve member.

Abstract: The rotary valve engine of the present invention comprises an engine block containing four power cylinders and a central valve cylinder. A single valve port is located in each cylinder just above the maximum travel of the piston. This port serves alternately as an intake port and as an exhaust port. A valve spool is rotatably mounted in the valve cylinder and includes a fuel-air channel in communication with a source of fuel-air mixture and an exhaust port in communication with the atmosphere. The valve spool is rotatable to cause the fuel-air channel and the exhaust channel to move into sequential communication with the valve port of each power cylinder so as to provide charging and exhausting of the power cylinders in proper succession. Two crank shafts are provided, and are linked together by external gears to cause synchronous counter-rotation in such a manner that intake compression, power and exhaust strokes are coordinated and the inertial forces of the engine are counter balanced at all times.

Abstract: A multicylinder two-stroke internal combustion engine has a plurality of reciprocating pistons arranged in a circle about a central cavity in which is located a rotary distributor driven in timed sequence with operation of the pistons. The rotary distributor includes internal cavities which may connect through ports in its outer cylindrical surface with the working cylinders to control the flow of intake air, scavenging air and/or fuel to the working cylinders. Scavenging air can be precompressed either in a preceding cylinder, taken in ignition order, or in the crank chambers beneath the pistons.

Abstract: A rotary internal combustion engine which includes a plurality of cylinders equiangularly mounted around a central rotary valve assembly on an axial horizontal shaft, in which more complete combustion and less emission of unburnt gases is achieved. The engine embodies a valving rotor comprising horizontally spaced discs having two properly located intake and exhaust valve passages and related generally cup-shaped intake/exhaust guide means eccentrically mounted on the shaft. This arrangement together with correspondingly horizontally spaced intake/exhaust ports in the respective cylinders, provides for dual intake charges and for the exhaust gas to be discharged twice and more completely in a single exhaust stroke via the properly located exhaust valves. The exhaust valves, which are also in the horizontally spaced rotor discs, are circumferentially displaced from the respective intake valves and also from each other.
