Water-in-diesel emulsion fuel (W/D) is one of the alternative fuel that capable to reduce the exhaust emission of diesel engine significantly especially the nitrogen oxides (NOx)and particulate matter (PM) The present paper investigates the effect of using W/D made from Malaysian low grade diesel (D2) on the diesel exhaust emission. Four different water percentages (5, 10, 15 and 20%) with constant 2% of surfactant were tested and labelled as E5, E10, E15 and E20, respectively. NOx and PM are found to be reduced for all types of W/D. E20 is reported to be the best in reducing NOx and PM with an average reduction of 41% and 35%, respectively, in every load condition. Overall, it is observed that the formation of W/D from low-grade diesel is an appropriate alternative fuel method that can bring about greener exhaust emissions and fuel savings without deteriorating engine performance.
