The opening and closing movements of the valves in an internal combustion engine have been controlled by camshaft rotation for around 150 years. The cam itself was invented by Al-Jazari in the year 1206 as part of a proto-drum machine. But now, in Koenigsegg's shop as it is in many other labs around the world, the cam is turning obsolete.
On this penultimate episode of Inside Koenigsegg, Christian Von K and Urban Carlson, CEO of Cargine — a developer of pneumatically driven valve actuators — offer keen insight into how camless engines will improve the efficiency and power output of internal combustion engines, both in Koenigsegg-grade supercars and in more, er, pedestrian cars too.
Imagine, as CVK says, an engine in which the valves can be controlled independently, like keys on a piano keyboard. The possibilities bode well for fine-tuning an engine's sucking and blowing, but also for optimizing its squeezing and banging as well.
