Fundamentals of Valve Design and Material Selection 660471

This paper reviews some of the fundamentals of valve train engineering as practiced by the engine designer. Valve proportions are considered in terms of engine volumetric efficiency, valve operating temperature, and stress conditions. Other factors influencing valve durability, such as valve train dynamics, cylinder head and seat design, and material selection, are also discussed. Common types of valve failures and their causes are appraised as a means of improving engine design.
