Abstract
Abstract This invention is a hybrid engine employing a reciprocating piston in conjunction with an electromagnetic transducer for control and power output. The transducer is essentially a specialized linear motor/generator. The piston is rigidly connected by means of a rod to a permanent magnet (or equivalent). The piston-rod-magnet unit is constrained by bearings to move translationally along one axis. The magnet can move linearly into and out of the yoke of the magnetic transducer to generate an electric current in the windings of the yoke. At the same time computer control of the effective impendences of these windings as well as computer controlled currents (provided by an electric storage battery or electrical energy storage indicator) flowing through some (or all) of these windings control the motion of the magnet and hence of the piston. Computer control is also exercised over other devices to regulate ignition timing, fuel injection, air intake, valve motion, etc. The power output may be used to drive A.C., D.C. or A.C./D.C. motors or it may be wholly or partially rectified to charge batteries and/or power A.C./D.C. or D.C. motors or to power other devices.
