ABSTRACT:
An improved engine construction having a reciprocating piston attached to a rotating crankshaft contains, proximate the piston head, a permanent magnet. A cylinder, confining the piston, has a head with an electromagnet located therein. A timed switching system reverses the polarity of the electromagnet, thus alternately attracting and repelling the piston and driving the attached rotating crankshaft.
