Considering the CO2 problem, regenerated vegetable oil methyl esters have many advantages as an alternative fuel for diesel engines. However, operating with them increases NOx emissions as compared with the gas oil. The present work is concerned with emulsified vegetable oil methyl esters characteristics and the effects of emulsified vegetable oil methyl esters on the exhaust emissions of a DI diesel engine. Increasing the water mass fraction of emulsified fuel decreased NOx and smoke emissions simultaneously below the 15% water mass fraction. It was suggested that the optimum water mass fraction was 15% with regard to the engine performance and exhaust emissions, and emulsified vegetable oil methyl esters can be used as an alternative fuel of petroleum diesel fuels.
