| Abstract: | This paper applies neural networks to diagnose the fault of diesel engines by using Scaled Conjugate Gradient Algorithm. First, the Scaled Conjugate Gradient Algorithm is discussed, then,the feature parameters and the kinds of fault used by diagnosing diesel engine fault are given. In addition, the best fit curve equations of feature parameters are extracted. At last, 6-135ZC diesel engine is exampled for this, and the neural networks is verified by using the fault data of diesel engine . Experimental result demonstrates that the result of diagnosis to diesel engine fault is of great accuracy , the application of neural networks to this field is useful and reliable . |
