Internal combustion engines are one of the major causes of pollution. These engines work by burning fuels, hence contaminating environment through the exhaust. Due to the mentioned reason, there is a need of an alternate technology which is reusable and environment-friendly. As an effort to control the effects of engine emissions, this research suggests an alternative technique known as Magnetic Repulsion Piston Engine (MRPE). MRPE is an environment-friendly and non-polluting engine that works on the principle of repulsion between same poles of the magnet. The aim of this research is to manufacture such an engine that can use the repulsion between the same poles of the magnet to produce power and rotate the crankshaft without changing the design of the IC engines. MRPE uses a permanent and an electromagnet to achieve repulsion. The permanent magnet is attached upon the piston whereas the electromagnet replaces the cam valve mechanism. This arrangement with the proper current timing of electromagnet drives the crankshaft. The modifications are made to one-cylinder IC engine for this particular study. Successful running of the engine using the magnet attraction and repulsion is achieved. The engine produced only 189 rpm under no load.
