As to achieve sustainable greening transportation, researchers has agreed that emulsion fuel could be an alternative fuel for diesel engine as it is useful for heavy transportation. Emulsion fuel is well-known in reducing the exhaust emission that had been produced by vehicles. This research has been conducted in order to investigate the exhaust emission in diesel engine such as, Nitrogen Oxides (NOx), Carbon Dioxide (CO2), Carbon Monoxide (CO) and Particulate Matter. There are two types of emulsion fuel tested as it differs in water percentage. E10 is an indicator for emulsion fuel with 10% of water and another one is E20 with 20% of water. To assure the stability of emulsion fuel, 1% of surfactant had been added. Test engine results shows that NOx and PM for emulsion fuels reduced by 60% and 14.11% respectively compared to D2. Meanwhile, CO2 and CO for emulsion fuels are increased compared to D2 by about 27.76% and 102.20% respectively.
