A hydraulic/magnetic engine, comprising an engine assembly. Crankcase means are affixed within the engine assembly, and crankshaft means are positioned in the crankcase means. Cylinder means comprise at least two first cylinders being encased in the engine assembly and each including a first piston, at least two second pistons, and an electro-magnetic third piston. A hydraulic system has a hydraulic fluid chamber. First electro-magnetic means generates a first electromotive force, wherein switching magnetic polarity between a first and second openings forces a first piston, at least two second pistons, and an electro-magnetic third piston to move upward and downward within their respective cylinders. Thus, rotating the crankshaft means in a predetermined direction after an initial activation of the crankshaft means by applying a short period of an electrical force. The first electro-magnetic means is within the engine assembly.
