摘　　要：本文介绍一种４区的现象学燃烧模型，它可根据小缸径直喷式柴油机实测示功图推求质量燃烧率与ＮＯｘ排放浓度。文中依据ＬＤ１１００型柴油机的试验结果，分析讨论了计算模型中各需选值的参数对推求结果的影响，并对比了用热力学模型或现象学模型求得的燃烧率的差别。This paper presents an introduction of a 4-zone phenomenological combustion model. by using this model, mass combustion rate and NOx emissions may be deduced from measured indicator diagram of D. I. diesel engines. Based on the tested data of type LD1100 diesel engine, the influencesof combustion system parameters and running parameters on measured results are discussed in this paper.The measured combustion rates by using phenomenological model are compared with that by using thermodynamic model, the difference between these two combustion rates has been discussed in this paper.
