Re: alternative to cams and valves ??

for some nifty ideas, check out BMW's Valvetronic engines. They get rid of the throttle altogether, and use the valves themselves to control engine speed. Also, new engines are coming out that use electric solenoids to operate the valves, eliminating the need for camshafts. this also allows infinitely variable valve timing.
