| Abstract: | A method for diagnosis of misfire fault in gasoline engine based on exhaust density HC, CO2 and O2 was presented,and a fuzzy figure describing the misfire degree was also introduced. A model which describing the relationship between the misfire degree and the gasoline engines exhaust emission was established based on RBF neural network, and the model was trained by test data and MATLAB software. The model was used to diagnosis gasoline engine misfire fault, the result illustrates that this diagnosis model is suitable. 2figs.,2tabs.,8refs. |
