摘　　要：试验在一台S195柴油机上进行,试验结果表明,新型多碳醇-柴油混合燃料的油耗率比纯柴油高,但随负荷的增大,差距呈下降趋势。新型混合燃料在较大工况范围都保持较低的CO排放量。新型混合燃料中,小比例多碳醇油料的加入有利于混合燃料的HC排放状况的改善,大比例多碳醇油料的加入,对改善混合燃料的HC排放影响不明显;新型混合燃料的NOx排放均比纯柴油低,并且小比例多碳醇-柴油混合燃料的NOx排放比其大比例混合燃料的NOx排放量低;新型混合燃料的碳烟排放均比纯柴油低,并且随着多碳醇掺混比例的增大,改善效果越好。The tests operated on an S195 diesel engine. Results showed that the fuel consumption rate of new hybrid fuel was higher than pure diesel fuel. But by the increaseing of load, the gap between the fuels droped, New hybrid fuel in larger conditions remained low range of CO emissions. Small proportion of the n-carbons alcohol was favorable on HC emissions, the large proportion of the n-carbons alcohol was disorganized. Furthermore, NOx emissions of the new hybrid fuel was lower than the pure diesel fuel, and the NOx emissions of small proportion n-carbons alcohol fuel waslower than the big proportion n-carbons alcohol fuel. The soot emissions of new hybrid fuel was lower than the pure diesel fuel, and as the proportion of the n-carbons alcohol increased the soot emissions decreased.
