The principle behind the Koenigsegg camless engine
Called Freevalve technology, this new way of actuating valves in a piston engine is quite simple conceptually, and offers a new realm of possibilities.
The way it works is elegant; all poppet valves sit on pneumatic springs that also are actuators, which are electronically controlled, this allows for almost infinite adjustment of valve timing, duration, and lift.
The modular architecture in this system makes for easy implementations in any possible cylinder configuration, further reducing weight, mechanical complexity, and power loss from driving mechanical components.
We are fortunate to witness these amazing developments happen within our lifetimes.
