Abstract: As the need of clean and green sources of energy is increasing with growing industrial requirement and population as the reserves of conventional fuel reserves are depleting exponential different countries are now taking lead in creating many reforms in order to achieve energy independence. In view of this objective several advance combustion technologies have now been developed, HCCI combustion engines being one of them. Several challenges are still restricting the use of this combustion technique over conventional internal combustion engine modules ie SI and CI engines few of such challeges includes flexibility in using different fuels, controlling the combustion rates, meeting the autoignition needs of the fuel, limited working range of such engines. Present work studies suitability of ethanol as working fuel in HCCI engines on different loading condition, since the autoignition temperature of ethanol based fuel will be higher test was conducted by preheating the charge on different engine loads to check the working domain of HCCI engine along with to easily attain the autoignition point use EGR is also tested along with the nature of emissions in terms of NOx and unburned hydrocarbon emissions.
