Slaughter, E E

This patent describes a non-idle method of operating an internal combustion engine including a rotary engine shaft; fuel supply means to supply fuel to the engine to cause the operation of the engine; an air compressor driven by rotation of the shaft and communicating with the engine to supply compressed air thereto for mixing with fuel to form a combustible mixture; spark means associated with the engine and controllable to cause the ignition of a fuel-air mixture therein to cause the rotation of the shaft; a compressed air reservoir storing excess compressed air from the compressor; an air valve connecting the reservoir with the compressor and the engine to control the flow of compressed air from the compressor to the reservoir and from the reservoir to the engine; an accelerator movable to operatively control the rotational speed of the engine shaft; shaft encoder means generating a shaft speed signal indicative of the rotational speed of the engine shaft; and an engine controller operatively interconnected with the fuel supply means, the spark means, the valve, the accelerator, and the shaft encoder.
