摘要:

车用乙醇汽油是由燃料乙醇与基础汽油以一定比例调合而成，调配时测定其辛烷值的频次较高。根据标准方法测定的辛烷值数据建立了乙醇汽油辛烷值预测模型，并对该模型进行了准确性和重现性验证。结果 表明，该模型不仅可以代替标准方法，而且能显著节省分析时间和费用，具有明显的经济效益。

Abstract:

Alcohol gasoline as vehicle fuel is prepared by fuel alcohol and gasoline, its octane number is frequently determined during preparation. The model of pre -determining octane number of alcohol gasoline is established on the basis of octane numbers obtaine
