| 摘 要： | 利用大型气相动力学计算软件包CHEMKIN,以温度敏感性和反应速率分析为基础,对液化石油气HCCI燃烧详细化学动力学模型进行了机理简化,得到一个包含33种组分和93个基元反应的简化机理.并对简化机理与详细机理不同边界条件下的缸内温度峰值、压力峰值、着火时刻进行了对比分析,结果表明,在较广的进气温度、进气压力、压缩比、燃空当量比范围内简化机理与详细机理能够保证基本吻合. |

| Abstract: | With the help of the CHEMKIN,the paper presents a reduced mechanism of LPG HCCI combustion,based on the analysis of the temperature sensitivity and reaction rate.The reduced mechanism has 33 species and 93 reactions.The results of the detailed and reduced mechanism are compared under different boundary conditions,such as initial temperature,initial pressure,compression ratio,fuel/air ratio.It shows that the temperature peak value,pressure peak value,ignition moment are familiar with each other. |
| Keywords: | temperature sensitivity LPG HCCI reduced mechanism |
