Research on Oil Ferrography Analysis Fault Diagnosis of Diesel Engine Based on BP Neural Network

The principle of attrition pattern recognition was discussed based on the research of the engine´s characteristic of wear particle and fault mechanism, establish the relationship between the wear particle and attrition pattern, the paper give a new method which can be used for engine´s fault diagnosis based on the ferrography technology, by using BP neural network established the fault diagnosis model, the diagnosis results indicate the reliability of this method.
