    Abstract: A valve control arrangement for internal combustion engines in which a hydraulic valve actuator with integral fluid reservoir is interactive with two camshafts (110, 120) to continuously and independently vary the valve duration. A modified intake system is provided to increase the effective area of the valves.

    Abstract: An intake and exhaust valve system deployed in an internal combustion engine that improves available charge flow through the engine, provides improved charge turbulence and swirl of charge during each intake stroke for better mixture, provides for multiple independent fuel mixing at the cylinder (12), allows the use of concentric intake and exhaust valves (22, 24) also providing for balanced charge entry exit symmetry. The intake and exhaust valve system includes using a plurality of two or more concentric valve assemblies per cylinder, each intake valve (22) being mounted within a hollow exhaust valve (24), the multiple intake and exhaust valve (22, 24) providing optimum, flow area entering and exiting the cylinder (12). Two or more charge passage openings (14) per cylinder strategically disposed enhances the uniform distribution of charge per unit time. Utilization of the present invention greatly increases the fuel efficiency of the engine, reduces emission pollution without sacrificing engine horsepower.

    Abstract: A valve arrangement is provided for supplying air to a combustion chamber of an internal combustion engine, the valve arrangement including a first valve, the first valve including a first valve head, a first valve stem and an internal cavity, which is partly located in the first valve stem and open towards a lower surface of the first valve head, a valve guide arranged to surround a portion of the first valve stem such that the first valve stem is movable in the valve guide along a longitudinal direction between an upper, closed position of the valve, and a lower, open position, in which open position air may be supplied to the combustion chamber past the first valve head, the valve guide including an air passage allowing supply of additional air to the combustion chamber via the internal cavity in the first valve, when the first valve is in its closed position. The valve arrangement includes a guide leakage preventing means for preventing liquid from leaking from a region externally of the first valve stem to the valve guide air passage.
