Özet:

 

A 2-degree of freedom model of the hydraulic valve lifter of  an internal combustion engine is investigated using different system  parameters.  The oil compressibility and bulk modulus are integrated  into the model.  System vibrations, friction forces between the parts,  forces derived from the finger follower and cam system, and check  valve criteria are considered within the model for the closest  possible data to the real mechanism.  The viscosity changes caused by  the engine temperature changes, the spring constant variations  resulting from the deformations and the plunger-body radial clearance  changes have been investigated.  Using different types of approaches,  the solutions of the computer simulation are analyzed to achieve the  best results.
