ABSTRACT:
The internal combustion engine includes a cylinder block and a cylinder head forming a plurality of cylinders with a piston in each cylinder, a camshaft to open and close intake and exhaust ports, and a crankshaft to enable the piston to move back and forth in a reciprocating motion, wherein the piston is formed with a plurality of passageways extending from spaced inlets around its circumferential edge towards spaced outlets around the center of the piston head, and wherein the actuating means for the camshaft opens the exhaust port of each cylinder before the end of the power stroke. The internal combustion engine runs with a four stroke cycle of operation, but develops a power stroke divided into two phases. During the first phase of the power stroke, the combustible fluid mixture in the variable volume chamber of each cylinder is ignited to develop power and move the piston due to the expansion of the fluid mixture in a closed chamber. During the second phase of the power stroke, the fluid mixture flowing through the passageway forms an escaping column of burning fluid mixture extending from the center of the piston head towards the exhaust port to develop a reaction force on the piston head to continue the power stroke.
