Evaluation of overhead camshaft valve actuation, carried out by General Motors, and results obtained; conventional pushrod-operated valve train is compared to direct-acting and rocker-actuated overhead camshaft systems by analytical and experimental means; effect of various methods of valve actuation on valve train weights, forces, and stresses is examined showing that principal advantage of overhead camshafts is increased natural frequency of valve train; resulting improved dynamic characteristics of valve-actuating mechanism make it possible to design camshaft profiles which expand useful operating range of high-speed engines.
