- Abstract
The paper presents the research regarding the rotational movement of a hydraulic tappet from a direct acting valve train system. Firstly the advantages and disadvantages of the tappet rotation during engine functioning are described. Then, a description of the virtual model of the direct acting valve train modeling process is made and the parameters that influence the rotational movement are presented. The results obtained with the virtual model are presented in comparison with the experimental results obtained by other authors. The conclusions revealed that the position of the camshaft, the engine speed and the friction coefficient have a significant influence on the hydraulic tappet rotation.
