The Internal Combustion engines (I.C engine) is a heat engine that converts chemical energy of fuel into mechanical energy. Chemical energy of a fuel is first converted into thermal energy by means of combustion or oxidation with air inside the engine. This thermal energy is again converted into useful work through mechanical mechanism of the
