Abstract: Wear of the valve train area in low-speed operation becomes critical as engines become capable of high-speed and high-power performance. This paper describes the development of a design process to secure for the valve train a constant supply of lubricant film with particular emphasis on maintaining optimum conditions of lubrication in the cam and follower system. With this design process, a valve train made of ordinary materials can be designed to achieve an improved level of scuffing resistance without reduction of maximum load capacity.

Keywords: cam and follower systems; engine valve trains; vehicle design; wear resistance; lubricant film; lubrication; scuffing resistance; maximum load capacity; vehicle design.
