A new method of using chemical kinetic reaction modeling to predict the Research Octane Number (RON) and Motor Octane Number (MON) of single component fuels and fuel mixtures is described and illustrated via comparisons between computed and experimental values obtained using the well-established ASTM test procedures in a Cooperative Fuels Research (CFR) engine. Comparisons include predictions of RON and MON for a large variety of neat fuels, studies determining the RON and MON of mixtures of primary reference fuels (PRF) and toluene, and studies of RON and MON for mixtures of single-component and multiple-component gasoline surrogate mixtures with ethanol. Advantages in costs, time, and experimental complexity of the kinetic modeling approach compared to the existing engine test procedures are discussed.

通过使用建立良好的ASTM获得的计算值和实验值之间的比较，描述并说明了一种使用化学动力学反应模型预测单组分燃料和燃料混合物的研究辛烷值（RON）和发动机辛烷值（MON）的新方法合作燃料研究（CFR）发动机中的测试程序。比较包括对多种纯净燃料的RON和MON的预测，确定主要参考燃料（PRF）和甲苯的混合物的RON和MON的研究以及对单组分和多组分汽油的混合物的RON和MON的研究用乙醇替代混合物。讨论了与现有发动机测试程序相比，动力学建模方法在成本，时间和实验复杂性方面的优势。
