Recently, the effect of fuel composition is investigated for reducing participate matters [1][2] and sulfuric oxides [3][4]. But several problems are remaining unable to be solved as matters stand. This paper studies the effect of sulfur compound on the combustion characteristics of diesel engine. In the experiments, DBDS(Di-tert, Butyl, Di-Sulfide) were mixed to the base fuel to vary the amount of sulfur compound in fuel oils. The direct injection diesel engine was operated with several test fuels taking the change in exhaust gases as well as cylinder pressure histories. The calorific value of each test fuels was also examined. It is obtained that the more DBDS mixed to the base fuel, the calorific value becomes lower thus the fuel consumption tends to be larger. The results suggest that the molecular structure of SOx has a strong influence on the PM emission, where the soluble organic fraction in PM reduces along with increasing of the sulfur mixed ratio.
