摘　　要：针对发动机以2,5-二甲基呋喃为燃料的工况,从发动机自身运行特点和2,5-二甲基呋喃燃烧对发动机运行的影响出发。通过对基础油与添加剂进行筛选评价,选用了天然气合成油与油溶性聚醚复合使用作为基础油;同时根据基础油及添加剂的复配结果,采用模糊综合评价法对全配方进行了评价,研制出一种2,5-二甲基呋喃掺燃柴油发动机油。经过实验理化性能分析,所研制的发动机油具有良好的清净分散性、氧化安定性、耐腐蚀性等;可很好地满足以2,5-二甲基呋喃为燃料的发动机的使用要求。Aiming at the conditions of engine take 2, 5-dimethylfur as fuel, take into account the influence of 2, 5-dimethylfur combustion to the operation of engine and the operational characteristics of engine. The base oils and additives are purposefully selected, the composite of Gas-to-Liquids（GTL） and oil-soluble polyether（OSP）is determined as base oil. Meanwhile, compound testing results of base oil and additives are evaluated according to fuzzy comprehensive evaluation method. A 2, 5-dimethylfur blened with diesel engine oil is developed. The physical and chemical characteristics of oil are tested in laboratory, the results show that,the developed oil has good detergent-dispersant performance, oxidation stability, corrosion resistance and other performances; it can well satisfy the engine for the fuel of 2, 5-dimethylfur in the field test.
