An emulsion is a dispersion system, where one phase is dispersed in another phase in the presence of an emulsifying agent (surfactant). Emulsion fuel can reduce the cylinder peak pressure of the combustion chamber than using pure diesel fuel. The addition of the mass flow rate can increase cylinder pressure, reduce BSFC, increase thermal efficiency, increase diesel engine power and reduce emissions. This research uses a single cylinder diesel by varying the electric supercharger from 1861.2 L/min, 3154.2 L/min and 3976.8 L/min with a load engine from 800-4000 watts. The water content of this emulsion is 30% by volume, and using surfactants (span 80 and tween 80). The water content of this emulsion is 30% by volume and using span80 and tween80 as surfactants. Optimal results obtained on 0,0812 kg/s variations with an increase in thermal efficiency of 12.6%, fuel consumption decreased by 24.5% from neat diesel fuel. As for the emissions produced at smoke opacity, HC, and CO by 9%, 21.35%, and 27% respectively. Cylinder pressure rises by 4.7% from neat diesel fuel when the mass flow rate is added. There is a decrease in heat release rate with 15% emulsion fuel from neat diesel fuel.
