Abstract
An engine includes an engine block with at least one cylinder bank including cylinder bores formed therein. A piston is reciprocatingly disposed in each of the cylinder bores. A crankshaft is rotatably mounted to the engine block. Connecting rods are rotatably attached to the crankshaft and are coupled to the piston. A cylinder head with intake valves and exhaust valves in fluid communication with the cylinder bores is mounted to each cylinder bank. At least one permanent magnet is disposed in a skirt of each piston. At least one electromagnet is positioned adjacent to the permanent magnet(s). A control system selectively provides an electrical current to the electromagnets to produce a desired magnetic field, wherein the magnetic field of the electromagnets cooperates with a magnetic field of the permanent magnets to affect a motion of the piston in respect of the engine block.
