Electromagnetic engine

The utility model relates to an engine technology realizing power output by magnetic principle. As the present technology applied is to put the permanent magnet piston in the cylinder block, the technology does not only restricts the engine's output capacity but also leads to serious demagnetization of the permanent magnet when operated in high temperature, thus bringing the technological problems such as low operation reliability. Based on these problems, the utility model provides a technical scheme of electromagnetic engine. Two sets of engine mechanism are set up side by side symmetrically in the electromagnetic engine, each engine mechanism including crankshaft and a driving piston of the engine's cylinder block connected to the crankshaft. The external part of the driving piston's cylinder block is equipped with permanent magnet, and the symmetric central position of the two sets of engine mechanisms are equipped with bipolar end surface and electromagnetism arranged opposite to the piston permanent magnet. The technical scheme enlarges the design space of engine series, avoids the harmful effects such as demagnetization of the permanent magnet when operated in high temperature, and has the technical characteristics of high reliability and long service life.
