【Abstract】 The composition of microemulsion diesel oil was discussed and the mass ratio of diesel oil,water,surface active agent and cosurfactant was determined in this paper.The prepared microemulsion diesel oil was used to make experiments of viscosity,stability,ratio of oil saving,tail-gas analysis and smoke intensity.The results showed that when the content of surface active agent was 3%,the cosurfactant content was 0.28% and the moisture content was 10.5%,the viscosity of microemulsion diesel oil met the national standard of fuel oil.The microemulsion diesel oil could be maintained for more than half a year when the temperature range was 5～60℃ and could save energy under all work conditions.Compared with the 0# diesel oil,when the combustion time was the same,the microemulsion diesel oil reduced CO by 8.3%,HC by 9.5% and NOx by 28.5%,which indicated the pollution reducing clearly.更多还原
