I would suggest that rotary valves could be used. Still better than this would be to use an engine type that does not require valves at all, the rotary. On Mazda street engines the primary intake is through the side plates of rotor housings. Like a two cycle engine the 'valve' timing is determined by the shape, size, and placement of this hole. Going to a wilder cam in these engines is the mere (:-)) matter of a few minutes with a hand grinder. Some kind of sliding plate over a larger orafice could do the trick for dynamic timing, and it doesn't have to operate at engine speed. The rotary is a true four-stroke cycle engine, not a two stroke. Joseph L. Wood, III AT&T Information Systems Laboratories, Holmdel (201) 834-3759 ariel!jlw
