A Review on Electromagnetic Piston

Abstract

The main objective of this project to design and construct an electrically operated engine i.e. Electromagnetic engine. this engine is totally different from ordinary IC engine, because of the inventory advancement in operating principals. We have changed the operating principle of IC engine by using the electromagnetic effect instead of combustion of fossil fuels. This engine works on the principle of magnetic repulsion between two magnets. This electromagnetic engine consists of two magnets, one of them is an Electromagnet and other one is a Permanent Magnet. Permanent Magnet acts as piston and Electromagnet is located at the top of the cylinder instead of spark plug and valve arrangement in IC Engines. In this way this engine does not contain any spark plug and fuel injection system. The Electromagnet is energized by a battery source of suitable voltage and when the electromagnet attract the piston, spring get compressed and it will repel the permanent magnet which is attached to the piston head. i.e. piston from TDC to BDC, which will result in the rotary motion of crank shaft. When the piston is at BDC the supply of Electromagnet is discontinued, the permanent magnet which was repelled to BDC will come back to its initial position i.e. TDC. This procedure completes one revolution of crank shaft i.e. our output work. A copper winding is also wound to the cylinder block to get additional power to the piston to reciprocate. This winding is connected to a battery to create a magnetic field inside the cylinder and reciprocate permanent magnet piston on basis of repulsion forces created by winding. The total power supplied by battery will be just to fulfil the copper losses of winding and power required to magnetize the windings.
