Camless engines have two major advantages, you can operate them at higher RPMs, and you have full variability of timing for a wide operating range. High RPM causes high stress and high friction losses, so you're only going to use them where mass is critical, aircraft and race cars. A wide operating range is only… » 9/24/14 7:57pm 9/24/14 7:57pm
