Abstract: The economy and emission performance of emulsified diesel fuel were simulated and analyzed based on the diesel en-gine model built by using GT-Power and the load characteristics of ED15 emulsified diesel and diesel at 1 500 r/min were com-pared .The simulation results show that the equivalent specific fuel consumptions of ED 10 ,ED15 ,ED20 and ED25 are lower that that of diesel at all loads except that the equivalent specific fuel consumptions of ED 10 and ED25 are slightly higher that of diesel at 25% loads .The NOx and soot emission reduce dramatically .The experiment results show that the economy and emis-sion of ED15 are better than other emulsified fuel and its equivalent specific fuel consumptions of 25% ,50% ,75% and 100%loads are lower than that of diesel ,which save 2 .9% ,3 .68% ,4 .2% and 0 .8% fuel respectively .In addition ,the reductions of NOx emission are 42 .7% ,37 .4% ,11 .9% and 12 .9% respectively and the reductions of soot are 37 .9% ,30% ,52% and 47 .8% respectively .
