摘要
建立了汽油机燃烧过程的多区诊断及预测模型 ,其中包括氮氧化物生成模型。在质量燃烧率的计算中 ,直接反映了紊流对燃烧过程的影响。编制了计算程序 ,进行了变参数性能预测计算。将已燃区按规定分成若干小区 ,多区模型更能真实地描述缸内的燃烧现象。
In this paper,a multi area diagnostic and predictive model are proposed for combustion process in gasoline engines. The model includes the nitrogen oxides (NO X) formation model.The calculation of mass combustion rate directly reflects the effects of turbulent on combustion.The computer program has been edited to estimate the engine performance with variable parameters.The combusted area is divided into several regions,and the multi area model can more truly describe the in cylinder combustion.
