Abstract: An electromagnetic engine and method capable of producing a high amount of mechanical power at a high efficiency. An electromagnet or piston operates within a cylinder having a stepped bore therein. The cylinder reciprocates while the piston only pivots. The power stroke occurs for a short duration midway between a top dead center position and a bottom dead center position. Axial magnetic forces are used to impart axial motion to the cylinder which causes rotation of the crankshaft. A plate is positioned within the cylinder up against the step. When the plate is in close proximity to the piston or electromagnet, and the centerline of the cylinder is at a right angle to the throw of the crankshaft, the electromagnet is energized. Sequential energization of each of a plurality of piston-cylinder combinations occurs during each crankshaft rotation.
