摘　　要：在一台高压共轨柴油机上,分别燃用间接液化煤制柴油、直接液化煤制柴油和二者两种不同比例的混合油进行试验,研究了不同燃油对发动机动力性、经济性和排放性能的影响。试验结果表明:与直接液化煤制柴油相比,燃用间接液化煤制柴油时,发动机动力性有所恶化,但经济性更好;NO x和CO2的排放较低,而PM和CO的排放则明显降低;燃用两种燃油的混合油时,发动机的各项性能介乎两者之间,趋势一致。A series of tests are conducted on a high pressure common rail diesel engine fueled with diesel from direct coal liquefaction （DDCL）, diesel from indirect coal liquefaction （DIDL） and their blend with different proportions respectively to investigate the effects of different fuels on the power performance, fuel economy and emis- sions of engine. The results show that compared with DDCL, the engine fueled with DICL has slightly poor power performance, but better fuel economy, lower NOx and CO2 emissions, and apparently lower emissions of PM and CO, while the corresponding performances of engine with blended fuel are in between with consistent trend.
