To construct the comprehensive reaction model that can predict the ignition timing in the homogeneous charge compression ignition(HCCI) engine cycles, ignition delay times(τ) were measured in a newly produced high-pressure shock tube. The reaction models for heptane, iso-octane, and toluene ignitions were updated by using the rate coefficients determined experimentally and theoretically for the key reactions. These model calculations could reproduce the observed. in the wide pressure range. However, the ignition delay times for two-component mixtures of these hydrocarbon fuels could not be reproduced by the reaction models constructed by combining each mechanism. These disagreements are caused by the cross reactions, which are the reactions between the radical intermediates, so elucidation of the cross reactions is a challenge for the future.

为了构建可以预测均质电荷压缩点火（HCCI）发动机循环中的点火时间的综合反应模型，在新生产的高压冲击管中测量了点火延迟时间（τ）。通过使用实验和理论上确定的速率系数来更新项项项，等辛烷和甲苯点火的反应模型。这些模型计算可以重现观察到的。在宽压力范围内。但是，这些碳氢化合物燃料的两个组分混合物的点火延迟时间不能由通过组合每个机制构建的反应模型来重现。这些分歧是由交叉反应引起的，即自由基中间体之间的反应，因此阐明交叉反应是未来的挑战。
