| Abstract: | In this paper the statistical simulation method is used to extract the fault features of engine parts and fuel system from corresponding engine sound and oil pressure fluctuation signals Moreover,the confidence range of these feature values are also given,thus achieving the quantitative diagnosis for the faults Practice shows that the statistical simulation method is reliable and practical in engine diagnosis |
