Abstract: On the basis of the analysis on the fault diagnosis characteristics of threeway catalytic converter (TWC) knowledge in the automobile, some measurements were used to establish a knowledge base, such as processing work state parameters of TWC in the automobile by using neural network method, acquiring knowledge by using multilayer neural network model and selforganizing neural network model, expressing knowledge by using the form of production rules and binary production rules, changing knowledge by using quantitative design module and knowledge base modules and remembering knowledge by using many neural networks. The Results show that forecasting accuracy rate of neural network fault diagnosis expert system of TWC is high and it is of great practicality.
