For the purpose of efficient combustion, SFC reduction and cleanexhaust emission, a kind of additive was developed for the diesel fuel property improvement. After the theorefical analysis and the experimental comparison,the composition of the diesel fuel additive was determined based on the optimization. With this diesel fuel additive, the power output of diesel engines increased by an average of 3.4 %,the SFC dropped by 4.3 % and the smoke index in the free acceleration operation condition dropped by 27.2 %.%经过理论研究和试验对比，在优化组合的基础上，确定了新研制的柴油添加剂的配方。新的柴油添加剂，使柴油机功率平均提高3.4%，油耗率平均降低4.3%，自由加速烟度降低27.2%。
