How Koenigsegg built an engine with no camshaft and why it matters. Koenigsegg developed a technology called Free Valve, which replaces the traditional camshaft with pneumatic actuators that control each valve independently. In normal engines, valve timing is fixed by a camshaft and crankshaft relationship, which limits performance and efficiency. Free Valve eliminates this mechanical linkage. Each valve opens and closes based on real time input, RPM throttle position, load, and air pressure. Th
