My son Eric is the youngest man in the world to operate a "camless" engine. (AURA 1993). Sure, we can open the valve to "max-lift" in 1-2 a ms (.002ms), THAT IS NOT BEST. The prefered method is a "low-lift" dither to match the air velocity needed by port size (inertia). This method will also SAVE WORK !
