Abstract

The aim of this paper is to measure the tappet rotation in OHC valve train system. Tappet is eccentric from the cam center to rotate for preventing the partial wear. The experimental system is developed to measure the tappet rotation by using the laser beam and optical fiber. The characteristics of tappet rotation is presented for various operating conctitions. Specially, it is observed that tappet is rotated at the base circle.
