The cylinder head includes an intake port (20), an exhaust port (30), a dual-function chamber (24), a poppet valve (40) positioned within the dual-function chamber (24), and a flapper valve (50) also positioned within the dual-function chamber (24), capable of sealing the intake port (20) from the dual-function chamber (24), capable of sealing the exhaust port (30) from the dual-function chamber (24). If the cylinder head (10) is for a two-cycle engine, an injector may be positioned within the cylinder head so that fuel is injected either within the dual-function chamber (24), or directly injected within the combustion chamber (18). A process of operating the cylinder head (10) in conjunction with an internal combustion engine is also disclosed.

Abstract: An improved internal combustion engine unit which includes a separating aperture between the cylinder and a separation chamber, and a separating valve adapted to control closing and opening the separating aperture. The separation chamber is connectable to the intake manifold and to the exhaust manifold, respectively, by the intake and exhaust apertures. Opening both the separating valve and the exhaust valve enables gas flow from the cylinder volume to the exhaust manifold through the open separating aperture, the separation chamber and the open exhaust aperture. Opening both the separating valve and the intake valve enables gas flow from the intake manifold to the cylinder volume through the open intake aperture, the separation chamber and the separating aperture. The intake valve and the exhaust valve are driven by solenoids controlled in turn by an engine computer. The separating valve is driven by a camshaft driven in turn by the engine.

Abstract: A pneumatically actuated valve assembly for use as intake and/or exhaust valves on two- ­or four-stroke internal combustion engines. The assembly includes a valve (100), valve housing (200), and compressed gas distribution and timing mechanisms (Figures 5-8). The valve (100) is comprised of a short light weight hollow cylindrical body with a capped lower end and an opened upper end. The valve is further defined by a plurality of ports (104) adjacent to the lower end and a collar (198) encircling the body adjacent the upper end. The valve housing (200) is hollow and tubular having a larger diameter upper section and a smaller diameter lower section in which the valve (100) slides up to close and down to open. The housing (200) further includes hollow channels which direct compressed gas, managed by the distribution and timing mechanism, alternately towards the areas above and below the valve collar at regular intervals to open and close the valve, respectively.

Abstract: An internal combustion engine with a plurality of cylinders operating in a four-stroke mode, with pistons moving with reciprocating motion, employs at least one holding tank shared among a plurality of cylinders, and wherein the holding tank conveys a pre-combustion gas (fuel-air mix in gasoline engines) from the cylinders via a return manifold for reinsertion into an intake manifold of the engine. Valving extracts a quantity of pre-combustion gas from a cylinder into the holding tank during a compression stroke for subsequent discharge into the return manifold to reduce the compression ratio to a value less than the expansion ratio.

Abstract: A valve-operating mechanism (48) for an internal combustion engine (10) having intake and exhaust valves (43, 46) and valve control members (82, 92) for controlling the intake and exhaust valves. The intake and exhaust valves are configured as dual valves having an outer valve (54, 65) and an inner valve (55, 66). The valve control members, at least during scavenging, simultaneously close the outer valves of the intake and exhaust valves, producing a non-overlapping state, and simultaneously open the inner valves of the intake and exhaust valves, producing an overlapping state.

Abstract: An internal combustion engine is provided in which an intake valve (9), which opens and closes an intake valve hole (7) formed in a cylinder head (3) so as to face a combustion chamber (5), has a hollow structure, and an exhaust valve hole (22) formed in the intake valve (9) is made to open and close by an exhaust valve (18) coaxially housed within the intake valve (9). The intake valve hole (7), which faces the combustion chamber (5), communicates directly with an intake port (8), and the exhaust valve hole (22), which faces the combustion chamber (5), communicates with an exhaust port (14) via an exhaust passage (21) formed within the hollow intake valve (9). It is thereby possible to ensure that the intake valve (9) has a large opening area, thus increasing the intake charging efficiency and, furthermore, since exhaust gas that has just come out of the combustion chamber (5) does not make direct contact with the cylinder head (3), which has a large heat capacity, any decrease in temperature of the exhaust gas can be minimized, thereby utilizing waste heat effectively.

Abstract: A fuel injection system includes a hydraulically-actuated electronically-controlled fuel injector (45) having a needle valve member (55) and an injector body (50) that defines a fuel pressurization chamber (75) that opens to a nozzle outlet (80). The needle valve member (55) is positioned in the injector body (50) and is moveable between an inject position at which the nozzle outlet (80) is open, and a blocked position at which the nozzle outlet (80) is blocked. A portion of the injector body (50) adjacent the nozzle outlet (80) is a mono gas valve member (51). The movement of the gas valve member (51) controls one or both of the intake and exhaust portions of the engine cycle. The gas valve member (51) is also hydraulically-actuated and electronically-controlled by the same hydraulic actuator (46) that operates the fuel injector (50).
