摘　　要：介绍了评价汽油品质的综合指标,对汽油池组分构成与汽油辛烷值标号、密度、发热值之间的关系进行了分析;评述了汽车发动机特性对汽油品质的要求及对汽油燃效的影响,研究了不同辛烷值标号、不同调和组分汽油的使用经济性,提出了正确选择辛烷值标号的方向。Composite indicators to evaluate the gasoline quality were introduced, and the relation between gasoline component, octane number, density and calorific value was analyzed. The requirements of motor-engine performance for the gasoline quality were discussed as well as the influence of engine performance on the combustion efficiency of gasoline. Meanwhile, the economy in use of gasoline with different octane numbers and components was researched. At last, how to properly choose octane numbers was pointed out.
