ABSTRACT:
A method and apparatus for controlling the air flow in an internal-combustion engine that comprises an unthrottled variable-timing third valve engine modification. An unthrottled full charge of air is drawn into the cylinders during the standard intake stroke of a four-stroke internal-combustion engine. During the initial portion of the succeeding compression stroke, a portion of that full charge is discharged through a third valve. Thus, the same mass of air that would result from throttled engine remains in the cylinders to be compressed. This air quantity is adjusted by means of adjusting the timing of the opening and closing of the third valve in accordance with the power requirements of the engine. A full charge of air is utilized for a full load, while a lesser charge is utilized for a partial load. Power losses which result from conventional intake air throttling are thereby eliminated.
