摘　　要：在F-T柴油中添加不同比例的丁醇、生物柴油燃料,并与0#柴油进行发动机性能对比研究。结果表明,相比于原机水平,混合燃料动力性能有10%的降低,经济性能变化不大,污染物排放量明显降低。在2 000 r/min时,混合燃料N10、N20与N10B10的NOx排放分别降低23.40%、26.95%和23.25%;外特性下,混合燃料N10、N20与N10B10的碳烟排放平均降低71.47%、77.16%和68.80%,甲醛平均降低幅度为59.19%、68.41%和62.75%。The effect of F-T diesel blending in varying proportions of butyl alcohol and biodiesel on the dynamic performance and emission characteristics is investigated and compared with 0# diesel fuel. Results show that, compared with the baseline diesel engine, the mixed fuel experiences 10% reduction of dynamic performance, little change in economic performance, whereas its pollutant emissions decrease significantly. At 2 000 r/min, NOx emissions of fuel N10,N20 and N10B10 are reduced by 23.40%, 26.95%, 23.25% respectively. Under the external characteristic, soot emissions of those three fuels are reduced by an average of 71.47%, 77.16% and 68.80% and the average reduction rate of formaldehyde is 59.19%, 68.41% and 62.75% respectively.
