| Abstract: | In this paper, a new method of fault diagnosis for diesel engine based on the exhaust emission is proposed. The parameters are defined from the emission measured data by the analysis of the emission. And the diagnosis model which is made up of the rule and the fuzzy network is built. Then the characteristic database and the plastidty principle are confirmed. Through the experimentation of fault diagnosis, we can conclude that this method of fault diagnosis is accurately, efficient and valuable. |
