- Abstract:
-
The dynamic characteristics of exhaust valve forced opening mechanism affect the engine light loadfuel-efficient valve timing mechanism’s working performance and reliability directly. The paper builds thevalve timing mechanism multi-body kinetics model in Adams,and analyzes the dynamic characteristics of ex-haust valve forced opening mechanism through simulation.The analysis results of simulation show that theforced opening force of exhaust valve is about 518.7 N,which is approximate to the test value 556 N,and thepiston rod can enter into the groove smoothly nearby the maximum opening stroke of exhaust valve and open theexhaust valve forcedly.
