摘　　要：探索通过添加不同比例的乙醇后对混合燃料低温流动性的改善效果。试验结果表明,20%黄连木生物柴油混合燃料,20%麻风树生物柴油混合燃料在乙醇添加比例为5%时,两种混合燃料的凝点、粘度都能下降到0#柴油的标准。The biodiesel is a clean fuel which will enable people to get away from dependence on fossil diesel, but freez- ing point and viscosity of biodiesel is relatively high which causes the bad low-temperature fluidity property when they mix with 0# diesel. In this paper, ethanol which has the good effect of low-temperature fluidity is added to the biodieseldiesel mixture. Result shows that both M20 and H20 have the same freezing point and viscosity as 0# diesel when the ethanol is added as 5%.
