Abstract: A computerized, self-contained, internal supercharged, positive displacement, internal combustion engine that transfers the work being generated in the combustion cylinder directly into useful work in a pump without the disadvantages of crankshafts, camshafts, and powertrain. A piston-rod assembly that has a much smaller frictional surface area replaces the above crankshafts, camshafts, and powertrain. The elimination of the crankshaft, and other associated parts reduces operational, maintenance, and manufacturing cost. Conventional engines that employ a crankshaft as a means of extracting work from the combustion cylinder have reached their innate design limits. This novel device will allow further development of the positive displacement, internal combustion engine; can be employed in certain applications that crankshafted devices cannot; and open new applications. It can be used directly as a pump or in systems requiring a pump. Its application can be stationary, mobile, and transportation vehicles.
