| Abstract: | On the basis of analyzing the features of cylinder head vibration signal in both time and frequency domain, the changes of this features caused by valve clearance fault are studied in detail and used to diagnose the valve mechanism fault. A new method is also presented to diagnose valve clearance fault quantitatively through valve closing time. |
