Alternative fuels providing diesel engine emission reductions are developed in order to provide practical solutions to environmental problems in different areas of the world. Diesel fuel emulsions containing water, considered as alternative fuels, have shown their potential to help reaching simultaneous reduction of NOx and PM exhaust emissions. In this study, diesel fuel microemulsions have been developed and optimized considering their cost-effectiveness. Water is incorporated into the fuel in the form of micelle structures, mostly using naturally derived surfactants. The finished fuel is visually transparent and thermodynamically stable over a wide range of storage and handling conditions. Experimental work was conducted to explore the impact of water in diesel fuel microemulsions on CIDI engine performance, regulated and non-regulated exhaust emissions.
