Abstract: In order to reduce smoke in a diesel engine, combustion test was conducted by using gas-oil blended with gasoline having a lower distillation temperature. It was found that smoke was decreased by about 80% in the low load case and about 50% in the high load case as the blending ratio of gasoline and gasoil increased to about unity. The soot particle size was estimated by analyzing the soot-formation and -oxidation processes based on the two-zone model. Analytical result shows that smoke is reduced mainly due to a decrease in soot particle size based on the lower evaporation temperature as well as the longer ignition delay based on gasoline blending.
