| Abstract: | This paper mainly introduces how to recognize the acoustical signals of the diesel engines using wavelet packet analysis and pattern identification. The fault diagnosis of the diesel engines is also introduced. Using the updated data base of experts, the fault of small diesel engines can be recognized. This technique is evaluated and applied for the fault diagnosis of the KM178F diesel engine, and good results are obtained. |
