Formulation of Oxygenated Water-in-diesel Fuel Emulsion and Investigation of Its Properties

The main interest of this research was to formulate highly stable, oxygenated water-in-diesel emulsion that gives minimum hazardous exhaust emission. Fatty acid methyl esters (FAME) are found to be very viable oxygenate amongst other four oxygenated components. The oxygenated W/D emulsion is formulated using 20% FAME, 10% water, and 5% blend of Span 80/Tween 80 and diesel. The properties of this oxygenated fuel emulsion are investigated. Though the viscosity of fuel is found to be increased, it is within the standard limit value. There is an improvement in oxygenated fuel emulsion in burning test, evaporation rate test, and calorific value.
