Abstract: A precision cooling system directs the flow of coolant to optimize coolant flow around the cylinders of an internal combustion engine. This results in lower temperatures in the upper portion of the cylinders, more uniform temperatures throughout the engine, and a lower average temperature. The precision cooling system is integrated into the construction of the water jacket distributing coolant throughout the engine and particularly around the combustion cylinders.

Abstract: A multi-cylinder internal combustion engine draws oil from an oil reservoir with an oil pump, and supplies oil to individual areas of the engine, after passing the oil through an oil filter and an oil cooler. A filter case containing an element of the oil filter is mounted to a side surface of the engine to facilitate the removal and replacement of the case. The oil cooler and a balancer are each respectively mounted to a front central portion of the internal combustion engine to enable oil cooling by an air-cooling effect of a running airflow, and to balance weight in the left-right direction of the internal combustion engine. Oil discharged from the oil cooler is introduced to a substantially central portion of the main gallery, to achieve uniformity of oil pressure supplied to individual bearing portions and uniformity of cooling of the individual bearing portions.

Abstract: An internal combustion reciprocation engine conjoined and integrated with a supplementary piston mechanism. The supplementary piston mechanism serves as a storage and return volume for fresh gases to be ignited during the power stroke. Thus, erasing the need for a combustion chamber at top dead center. The storage occurs during the intake or compression stroke through a small volume gaseous communication conduit to the top of supplementary piston mechanism. And is returned to the top of the main power piston during the power stroke through the same small volume gaseous communication conduit. Ignition in the power stroke occurs as the supplementary piston mechanism working in supplementation with the main power piston achieves the proper compression ratio. The high combustion pressure provided by the ignition is then transfered to the the crankshaft through the connecting rod with greater advantage late in the power stroke.

Abstract: A dual system for overall engine emissions control, including prevention of excessive formation of nitrogen oxides and carbon compounds 1) by cooling and humidifying intake air and 2) by restructuring and modifying hydrocarbon fuels, resulting in a more complete combustion, a significant reduction of the latent heat of combustion and increased combustion potency. The invention utilizes one or more ultrasonic devices to create an aqueous vapor from an ultra-pure water supply, said vapor varying in quantity according to engine size and load, having electronic sensors and controls for precision switching, metering and delivery. Simultaneously, while humidifying the intake air, the hydrocarbon fuel is passed from a fuel supply through a catalytic reactor to restructure the hydrocarbon molecules into a more homogeneous, more combustible and cleaner-burning fuel. Thus equipped, said internal combustion engine can be run as a fuel conserving, low emissions prime mover.

Abstract: The present invention provides a system that controls the amount and timing of pilot fuel injection to obtain minimum NOx and UHC emissions. The system senses if combustion occurs, when combustion occurs, and/or the quality of combustion in the combustion chamber of each cylinder of the gaseous fuel engine and adjusts the amount and/or timing of the pilot fuel injected. The minimum amount of pilot fuel needed to ignite gaseous fuel in a combustion chamber is determined and injected into the prechamber or the combustion chamber of the engine. The actual start of combustion location is determined and the injection timing is adjusted if the start of combustion location is not approximately equal to a desired location. The amount of pilot fuel or injection timing is adjusted if a knock or a misfire has occurred or if the combustion quality measure is not approximately equal to a desired quality measure.
