摘　　要：本文对经改装成火花点火式的S195柴油机燃用变组分煤层气的燃烧模型进行了研究。以MATLAB程序设计语言为基本应用平台,建立了缸内燃烧过程的变步长双区准维模型,并与试验结果进行了比较分析,同时分析了组分变化对燃烧过程的影响。结果表明,本文所建立的模型是合理的,能较好地反映缸内的实际工作过程。A kind of combustion model of the SI95 diesel engine refitted to a spark ignition engine fuelled by various components coal bed methane was studied. A quasi-dimensional two-zone combustion model with varying steps was developed by using MATLAB language. The differences between calculated results and experimental values were analyzed. The results show that the combustion model is feasible and can describe the real working process of internal combustion engines.
