In order to extract self-contained features which can reflect state information roundly from engine cylinder head vibration signals, a feature parameter system adapting to extract online is built. Characteristics of signals and qualities of lifting wavelet package transform are taken into account in the feature parameter system. Three qualities of lifting wavelet package transform, including irrelevance, reversibility and changeless sequence are concluded. De-noising, feature extraction and eliminating fluctuation are integrated in one decomposition and reconstruction process of lifting wavelet package. The integrated feature extraction model for engine cylinder head vibration signal is built. The calculation formula integrated eliminating fluctuation and standardization formula for feature value are given. The work process of the integrated feature extraction model is illustrated with an example.
