The Research on Fault Diagnosis for Diesel Engines based on BP Neural Networks

摘要

The paper analyzes the limitations on the traditional fault diagnosis in the engine fault diagnosis ,and than propose neural network system based on intelligent diagnosis combined with the characteristics of diesel engines. It also proposes neural network system based on intelligent diagnosis and discusses the principles of the diagnosis and the learning rules of the BP Neural Networks. Through a large number of the diagnostic test results show that, Using BP neural network fault diagnosis method can effectively improve the accuracy of diesel engine fault diagnosis and effectiveness.
