使用Chemkin 4.02[1]的内燃机模型测试并比较了甲烷燃烧的三种化学动力学机制：一步全局反应机制、四步机制和标准详细方案GRIMECH 3.0。这项研究显示出良好的一致性，特别是在温度和主要物种概况预测的四步和详细机制之间。但简化方案无法预测内燃机中的污染物排放。四步机制只能预测二氧化碳排放量，但一致性较差。
Three chemical kinetic mechanisms of methane combustion were tested and compared using the internal combustion engine model of Chemkin 4.02 [1]: one-step global reaction mechanism, four-step mechanism, and the standard detailed scheme GRIMECH 3.0. This study shows good concordances, especially between the four-step and the detailed mechanisms in the prediction of temperature and main species profiles. But reduced schemes were incapables to predict pollutant emissions in an internal combustion engine. The four-step mechanism can only predict CO emissions but without good agreement.
