【摘要】 随着HCCI燃烧技术的不断发展,燃料化学动力学机理在燃烧计算中发挥着越来越重要的作用.纵览了近年来基础燃料各种不同类型反应机理与试验研究情况,为评价现有反应机理对HCCI发动机燃烧过程的适用性,将机理模型的计算结果与HCCI燃烧相关试验进行了综合比较验证.通过4种典型基础燃料机理的计算与激波管、速压机和HCCI发动机等试验数据的比较发现,由于各反应机理构建的目的和方法不同,以及针对个别验证试验作出的参数调整,各机理在不同试验状况下性能各异,为此提出了构建适用于HCCI发动机的基础燃料简化机理的必要性.更多还原

【Abstract】 With the development of homogenous charge compression ignition(HCCI)combustion technol-ogy,the chemical kinetic mechanism becomes more important.An review on the currently available pri-mary reference fuels(PRF)oxidation mechanisms and experiments is discussed.The mechanisms need to be compared with experiments of HCCI combustion to evaluate the prediction in HCCI engine.Compari-sons of experimental data include those from shock tube,rapid compression machine,and HCCI engine with calculated results using four typical reaction mechanisms indicate that different models from different experimental conditions are presented due to different purposes and approaches,and adjusting parameters for specified validated experiment during mechanism construction.The necessity in developing PRF re-duced mechanism for HCCI combustion is addressed.更多还原
