Mutation points of vibration signals usually contain much malfunction information. It is a valid method to monitor its vibration signals from the surface for fault diagnosis. Neural-network and linear programming model are combined to form a two-stage system for prediction of vibration signals. An illustrative example shows that this method can accurately diagnose malfunctions of diesel engine and monitor its operational condition. The illustrative example shows if enough samples are used to train the two-stage prediction model, the prediction error of non-stationary vibration signals from diesel engine is acceptable. The method can be used to predict mutation in the vibration signals of a diesel engine. Monitoring the surface vibration signals of the diesel engine can predict its malfunction.
