摘　　要：进行了295T型直喷柴油机燃用掺入不同比例生物柴油的混合燃料的试验研究。试验结果表明:掺烧生物柴油发动机转矩和功率略有下降,燃油消耗率增加,HC排放量显著减少,NOX排放量略有增加,CO、烟度在中低负荷阶段无明显变化,在高负荷阶段CO、碳烟排放显著减少。随着掺烧生物柴油比例的增加,CO以及HC、碳烟排放量有下降趋势,NOx排放量增加。This paper studies the performances of direct injection 295T engine fueled with different proportion of bio - diesel mixed fuel. The result shows that blending bio - diesel the power and torque decreased slightly, HC emissions sig- nificantly reduced and NOx rises slightly and the consumption increased. The amounts of CO, carbon smoke emissions in the low - load stage and middle load stage have no significant changes, but in high - load stage of the CO, carbon smoke emissions mixed with bio - diesel fuel have a significant reduction ; as the increase of the percentage of bio - diesel fuel the CO, HC and carbon smoke emissions reduced, but the NOx rises slightly.
