| Abstract: | The paper introduces the matching pursuit and signal decomposing method which is employed in the diesel engine fault diagnosis.Taking the in-take valve vibration signal of Cummins 6BT5.9 diesel engine as the example,the Gaus function is selected as the decomposing base unit function,which has better property in time-domain,to analyze the vibration signal.The method and conclusions are proved by experiment. |
