摘　　要：双通道镶块结构在一定程度上提升了涡流室柴油机的性能,在该结构基础上掺烧生物柴油,探究双通道镶块涡流室柴油机掺烧生物柴油的综合性能。通过发动机台架试验得到了双通道镶块涡流室柴油机掺烧生物柴油时的各项性能指标,分析生物柴油掺烧比对双通道镶块涡流室柴油机性能的影响规律。试验得出:掺烧生物柴油会降低发动机的最大输出功率,降幅随掺烧比增加而增大,掺烧比低于30%时对发动机动力性能影响较小:掺烧生物柴油会增加燃油消耗率,但部分工况下的等效燃油消耗率有所降低:掺烧生物柴油有利于碳烟、HC、CO的排放控制,但掺烧比大于20%时会导致NO_X排放增加。The structure of two - channel insert bloc k have an improvement on the chamber diesel engine. Do biodiesel blending test based on that structure, to get BSFC,smoke emission,NOX emission and HC emission, analysis the influence laws of blending ratio on the per-formance. The results show that the blending combustion makes the power reduce, and the degree increase withthe blend ratio. When the blending rat io is under 30 percent,the effects on the engine blending combustion makes the effective fuel consumption increase, but the equivalent fuel consumption isdecreased. The blending combustion have a positive effect on the control of smoke,HC and CO emission. Whenthe blending ratio is no more than 20 percent,the NOx emission is close to the NOx pure diesel fuel .
