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。
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 obtained by the standard method, and its precise and repeatability are validated. The result shows that the model can not only replace the standard method (GB/T 5487 and GB/T 503), but also remarkably save analysis time and expenses and have obvious economic benefits.
