An isoparametric element dynamic model for the valve gear of I.C. engine is established in this paper, the dynamic responses of the valve gear of PA6 280 diesel engine is also analysed, the calculated results tally with the measured valve in self vibration frequency, valve lifts and valve acceleration. The results also show that the valve gear of this engine will send flying when it works at high speed and the impulse is considerable when the valves lift.
