车用汽油机污染物排放特性模糊分析方法及应用研究

Research on fuzzy analysis of exhaust emission in automotive gasoline engines and it's application

采用模糊聚类理论分别对汽油机排气有害成分之间及排气有害成分与各工况因子之间进行聚类分析 ,为系统地研究影响汽车排气有害成分生成主要影响因素提出新的方法 ;采用模糊理论中的构造多元隶属函数的方法 ,对汽油机在有故障工况下的排放特性进行分析 。

This paper analyses the relationship between the degree of combustion completely and the exhaust emission.The relationship between the exhaust emission and many kinds of working parameters of engine based on the theory of fuzzy classification is analysed too.Finally a new method for fault diagnosis through forming multi parameter membership function is presented in this paper.
