Research on the Fault Diagnosis Technology of Diesel Engine Based on the Instantaneous Speed

摘要：

The instantaneous speed signals of diesel contain lots of information about machine states,which is useful for fault diagnosis of diesel engine.Mixed fault diagnosis method of diesel engine based on the instantaneous speed has been proposed,which combines with the lower order angular vibration amplitude and SOM neural network to diagnose the cylinder pressure fault,then extracts three feature parameters of instantaneous speed to locate the fault cylinder.The method can detect the cylinder pressure fault accurately in diesel engine and locate the fault cylinder.The experimental confirmation shows that it has good effect on fault diagnosis of diesel engine.
