Title:
ELECTROMAGNETIC PISTON ENGINE
Document Type and Number:
WIPO Patent Application WO/1997/023728
Kind Code:
A1
Abstract:
An electromagnetic piston engine which produces driving power from the reciprocating motion of the piston in the cylinder caused by electromagnetic force. The various kinds of resistances of conventional internal combustion engines are eliminated, the weight of the rotating section is reduced to a small value even though a large output is taken out from the engine, a conventional driving powder transmitting mechanism for internal piston engines can be used, and the energy utilization factor is high. The cylinder and piston are made of magnetic materials. The engine includes a cylinder electromagnet whose one magnetic pole is the internal wall of the cylinder and a piston magnetizer which fixedly magnetizes the part of the piston which is fitted into the cylinder to a single magnetic pole. The piston is moved in one direction by the magnetic attracting force between the cylinder and the piston produced by the cylinder electromagnet, and then moved in the opposite direction by the magnetic repulsive force produced by reversely exciting the cylinder electromagnet. The magnetic attracting force and repulsive force are repeatedly produced alternately, the piston continuously makes the reciprocating motion.
