Abstract: This invention presents a method to improve the volumetric efficiency of a reciprocating internal combustion engine using a common transfer port between the exhaust and intake port. The engine employs a poppet valve as part of the intake and exhaust valve to control the flow from the transfer port into the combustion chamber. Two plate type valves outside of the combustion chamber are located at both ends of the transfer port to control the flow coming from the intake and out the exhaust. The timing for opening and closing of the poppet type valve is regulated to remain open for a longer duration which provides complete evacuation of air in the exhaust stroke. The ejector effect from the exhaust flow through the transfer port draws a vacuum into the cylinder. When the exhaust plate closes, the vacuum diverts the intake into the cylinder.

Abstract: A cylinder head for an internal combustion engine has a body, a rigid center spacedly surrounded by the body, an annular outer valve seat on the body, and an annular inner valve seat on the center. A ring-shaped valve has an outer seat face and an inner seat face and is displaceable along an axis into a closed position bearing on the outer valve seat with the outer seat face and on the inner valve seat with the inner seat face. The inner valve seat or outer valve seat is slidable axially. A seal member set in a groove in the center or in the body engages the one slidable seat. At least one biasing member connected to the one slidable valve seat urges same toward the ring-shaped valve.

Abstract: A valve mechanism with a variable valve opening cross section disposed in a passageway of an internal combustion engine and has a gas exchange valve that is acted on by the force of a valve spring and can be slid back and forth in the axial direction inside a guide by a valve control unit. Coaxial to the gas exchange valve is a seal valve acted on by the force of a coupling spring and can be slid back and forth in the axial direction by the valve control unit. The position of the seal valve in relation to the gas exchange valve in the axial direction can be changed by an adjusting unit.

Abstract: In known inlet valves, condensation of the fuel, which is precipitated in the form of a wall film, occurs at the inlet valve, in particular when the internal combustion engine is in the cold state. Relatively large fuel droplets, which cause an increase in the harmful components in the exhaust gas, can break away from the wall film. The inlet valve according to the invention has a hollow shaft into which compressed air flows via at least one inlet shaft opening, the compressed air then flowing out again from at least one outlet opening which is provided on one side of the inlet valve facing away from the combustion space of the internal combustion engine. As a result of the outflowing compressed air, an air film is produced around the valve head, which air film prevents condensation of the fuel. The inlet valve is provided in particular for mixture-compressing, spark ignition internal combustion engines.

Abstract: The invention relates to new and useful improvements in those types of internal combustion engines which employ a single poppet valve to alternately control both the intake and exhaust flows through the same valve port. The exhaust and intake air interact within a common manifold wherein mixing is prevented by means of pneumatic elements comprising a nozzle and diffuser combination which direct the flow. The invention improves the separation of intake air and exhaust gases within the manifold of engines of this character by curving the flow axis of the diffuser such that its exit plane is more or less aligned with the logitudinal flow axis of the exhaust pipe. A means of throttling the engine by proportionally distributing the intake air within the said manifold between the airchest and exhaust gas circuits in a manner relative to the engine speed is a further improvement. The method of indirectly injecting fluid into the engine through the valve well is improved by moving the injection cup nearer to the combustion chamber and by contouring its inner surfaces in contact with the alternately bidirectional flow of the intake and exhaust streams such that the temperature of the evaporated injection fluid is higher.
