The compression of air when drifting is greater in an enginewith piston valves than in one with plain valves because of thesmaller clearance spaces and the inability of the valves to lift. of engine No. 291S illustrate the effect of the Sheedy circulat-ing pipe. These cards were taken with and without the pipein action and comparisons may be drawn at very nearly thesame speeds.
