中文摘要：

对参比燃料、甲醇及甲醇—参比燃料混合燃料的主要反应历程进行了分析,利用详细反应机理研究了甲醇—参比燃料混合燃料燃烧时基元反应的相互影响特性。采用集总反应法构建了一个包含45种物质、75个反应的甲醇—参比燃料混合燃料简化反应机理,并利用激波管试验、流反应器试验、详细机理计算结果和HCCI发动机试验对该简化机理进行验证。结果表明,简化机理计算结果与试验结果及详细机理计算结果能够很好地吻合。

英文摘要：

The main reaction course of primary reference fuel（PRF）,methanol and their blended fuel was analyzed and the mutual influences between elementary reactions during the methanol-PRF blended fuel combustion were researched based on the detailed reaction mechanism.The simplified reaction mechanism,which contained 75 reactions and 45 substances,for methanol-PRF blended fuel was constructed.In addition,the mechanism was testified by shock tube experiments,flow reactor experiments,detailed mechanism calculated results and HCCI engine experiments.The results show that the simplified mechanism calculated results have a good agreement with the experiments results and the detailed mechanism calculated results.
