In reply to detrimental environmental conditions from batch depletion of gasoline fuels as well as global petroleum reserves being limited, many countries initiate to find solution for meeting the future demand of fuel used for transport. Ethanol-gasoline fuel blends have already been commercialized in many countries including India. Gasoline-alcohol-H2O based micro-emulsion fuel substitute a new and economically a better option. Micro-emulsions are thermodynamically stable so it has received lot of consideration because of physicochemical behaviour, and diverse applications. Lot of work has already been done in the areas of micro emulsion gels and preparation of vitamin E emulsions. But preparing, characterizing, and testing of micro emulsion fuels composed of Gasoline-H2O and especially of ethanolblended gasoline and H2O,used in spark ignition engines remain virtually unexplored. In this work we have prepared blends of various micro emulsion compositions of gasoline-ethanol and water in definite proportions, and tested the performance and emission characteristics in AVL Boost software in order to see if micro emulsion fuel is efficient in terms of performance and exhaust emissions. It was observed that micro emulsion fuel is more efficient as power increased and exhaust emission were reduced.
