The push rod type cam and follower mechanisms are extensively used in many mechanical systems prominent among them being the internal combustion engine. It comprises of several tribo pairs: cam and follower, valve and its guide, valve and its seat, rocker arm, tappet and its guide. The tribological performance of the various tribo interfaces affects the overall working of the mechanical system. The paper presents the kinematic and dynamic analysis of push rod type valve system for the determination of the friction between the various tribo pairs.

Keywords: Design, tribology, engine valve, cam profile, lubricant film thickness
