摘　　要：通过汽油机台架试验,对一种加入汽油中的改性生物基添加剂组成及其添加比例对发动机燃油经济性的作用及效果进行了研究。结果表明,尽管增溶剂能提高添加剂原液与汽油在低温下的互溶性,但是仅加入增溶剂对发动机的燃油经济性几乎没有任何改善;添加剂原液对发动机燃油经济性的改善幅度最大,最高可达8％左右,而且存在一个最佳添加比例,以使发动机获得最好的综合性能。The effect of the gasoline with solubilizer modified bio-additive component and its adding amount on the engine fuel economy were investigated through bench test. Although the solubilizer could increase the solubility of the original bio-additive in gasoline at low temperature, but the solubilizer itself basically could not improve the engine fuel economy. The original bio-additive could significantly improved the engine fuel economy as high as around 8%, however, for achieving better comprehensive performance of the engine, there existed an optimum volumetric proportion of additive in gasoline.
