通过分析各种不同的异辛烷反应机理的概况,发现由于反应机理构造的目的和方法的不同,各反应机理适用的范围有所限制。为了评价反应机理对HCC I发动机燃烧过程的适用性,必须将它们的计算结果与HCC I燃烧相关的实验进行综合比较。采用零维单区模型,通过5种不同反应机理的计算与速压机、激波管和HCC I发动机等实验数据的比较发现,各反应机理在不同实验状况下性能各异,在此基础上提出了构造适用于HCC I燃烧过程的异辛烷简化机理的必要性。
By analyzing the general situation of various isooctane reaction mechanisms, it is found that the scope of application of each reaction mechanism is limited due to the different purposes and methods of the reaction mechanism. In order to evaluate the applicability of the reaction mechanism to the HCC I engine combustion process, a comprehensive comparison of their calculations with those related to HCC I combustion must be made. Using zero-dimensional single-zone model and comparison of the experimental data of five different reaction mechanisms with the speed press, shock tube and HCC I engine, it is found that each reaction mechanism has different performance under different experimental conditions. Based on this The necessity of constructing a simplified isooctane mechanism for HCC I combustion is proposed.
