For instan eous nonlinear characteristics of vibration signals of diesel engine, the diesel engine vibration signal of the intrinsic mode function (IMF) component is used to identify the characteristic frequency band of the new method. The diesel engine vibration signal by the empirical mode decomposition, and remove the main interference factors of the IMF component, then the rest of the IMF component refactoring diesel engine vibration signal
