Abstract
THE author present a method for calculating high-speed motion of a cam-actuated engine valve, operated with a flexible linkage.
Correlation between calculated and experimental valve motion is shown to be reasonably good. The designer is enabled to understand the valve-motion phenomenon, and to predict it quantitatively, thereby eliminating many of the usual expensive trial processes.
Discussion of this and other papers on “Valve-Gear Problems in Modern Overhead-Valve Engines” starts on page 714.
