Abstract: A method for ensuring a good ring seal is for use in assembling a new engine or rebuilding an engine. The method comprises in each aspect use of a start-up lubricating composition comprised of a powder blend of (a) molybdenum disulfide, tungsten disulfide or a mixture thereof, (b) boron nitride, and (c) an inorganic fluoride, all suspended in a carrier fluid.

Abstract: A rotary valve internal combustion engine has a piston connected to a crankshaft and reciprocatable in a cylinder, a combustion chamber being defined in part by the piston, and a rotary valve rotatable in a valve housing fixed relative to the cylinder, the rotary valve having a valve body containing a volume defining, in part, the combustion chamber and further having a port giving, during rotation of the valve, fluid communication successively to and from the combustion chamber via inlet and exhaust ports.

Abstract: An inlet and exhaust valve arrangement for an internal combustion engine with a valve disk has at least one passage opening and is arranged in a cylinder head drivable by a shaft in a rotating manner and having a valve seat assigned to a top of the valve disk and at least a port that during rotation of the valve disk is cyclically exposed and closed again by at least one passage opening. The valve disk and the assigned valve seat starting from the shaft run in curve or taper at an angle toward a bottom of the valve disk. The valve disk is elastically bendable such that during rotation the valve disk is deflected and an edge of the valve disk is moved toward the valve seat to define therewith a self-sealing valve arrangement.

Abstract: An internal combustion engine includes a rotary valve such that said rotary valve serves as an output shaft for said engine.

Abstract: An internal combustion engine wherein each cylinder has two pistons placed in the opposite direction and attached together by an arm-type connecting rod and wherein a cylinder head has a rotor blade rotating in the middle between the upper cylinder head and the lower cylinder head whereby the upper cylinder head and the lower cylinder head are perforated with an intake port and an exhaust port. The rotor blade is perforated with one port and rotates by a gear which is at the outer edge of the rotor blade. When the piston reaches the power stroke, it generates force to act on the arm-type connecting rod and when the connecting rod arm moves in a linear motion, it transmits the force towards the crankshaft or the transmission shaft which is attached by a guide rail platform.

Abstract: An engine comprises an engine block having at least one combustion chamber and a rotary valve rotatably mounted on top of the engine block. The rotary valve includes an intake passage for diverting air into the combustion chamber and an exhaust passage for exhausting combustion by products from the combustion chamber. The engine further includes a head surrounding the rotary valve. Seals surrounding the combustion chamber seat against the bottom surface of the rotary valve. Seals on the circumference of the rotary valve seat against the head. The seals are arranged to provide a double seal for the combustion chamber during the initial portion of the power stroke. The rotary valve may further include a pressure relief valve to reduce pressure and temperature in the combustion chamber during at least a portion of the power cycle.
