| Abstract: | A dynamic analytical calculation for valvegear of an overhead camshaft engine is performed by utilizing a finite element dynamic model. The regularity of its valve kinematics and each order of natural vibration frequency and vibration pattern of valve gear in different camshaft speeds are found under the condition of known data of cam lift. Meanwhile the influence of oil temperature, oil pressure and amount of air bubble mixed in oil upon the operation of hydraulic va1ue lash adjuster,consequently, upon the kinematic characteristic of valve gear is studied as well. |
