摘　　要：研究了在常温下含不同乙醇比例的乙醇-柴油对助溶剂庚醇所需量及所需搅拌时间.测定不同比例乙醇-柴油混合燃料的燃烧值,确定乙醇在乙醇-柴油混合燃料的最佳配比.还研究了添加剂二茂铁对乙醇-柴油混合燃料燃烧效率的影响.结果表明:当混合燃料中乙醇含量为12%,庚醇含量为8.69%时,乙醇-柴油混合燃料的燃烧热与相应乙醇和柴油的燃烧热之和相比,热量损失较少,为0.97%.当混合燃料中添加二茂铁含量为0.7%时,燃烧值平均增加0.988%,相应的炭渣残余量最小.In order to make sure the best proportions of ethanol in the ethanol-diesel oil fuel, this experiment is made to study the needed amount of heptyl alcohol and the needed time to stir of the ethanoldiesel oil with different proportions at the room temperature. The burning value of ethanol-diesel with different proportions is also measured and researches have been done into the ferrocenes influence on the combustion efficiency of the ethanol-diesel oil mixed fuel. The result shows： compare the burning caloric of the ethanol-diesel oil mixed fuel which consists of 12 % ethanol and 8.69 % heptyl alcohol with the sum of corresponding ethanol and diesel oil, the loss of caloric is the least 0.97 %. When 0.7 % ferrocene is added, the combustion efficiency of ethanol-diesel oil mixed fuel equally increases by 0.988 %, and the corresponding coal sediment is minimum.
