Aside from building the world’s most exciting cars, Christian von Koenigsegg has long been involved in developing new technologies, one of which is a road-going engine that forgoes a traditional camshaft. The work of Koenigsegg’s sister company, FreeValve, Pneumatic Hydraulic Electric Actuator (PHEA) tech was introduced as a concept at this year’s Beijing Auto Show with local automaker Qoros.
This new video from /Drive, one of many from the /Inside Koenigsegg series, gives us a better look at the FreeValve engine, with Koenigsegg on hand as always to explain the technicalities involved, as well as the benefits to be gained from the technology – smaller engine size, lower engine weight, improved efficiency and performance, less emissions, lower costs and less complexity.
The development unit here is based on an existing Qoros 1.6 litre port-injected turbo mill found in its existing vehicles, modified to accommodate the engine’s new valves that feature pneumatic value actuators. The electronically-controlled system allows each valve to open or close individually via springs or air pressure, allowing for better control over the combustion process.
In terms of numbers, the engine in its standard guise produces 160 hp and 240 Nm of torque, but with the FreeValve technology, it now produces 240 hp and 320 Nm. Fuel consumption is also improved by up to 15%, while emissions are down by 35%.
It isn’t far-fetched to say that FreeValve technology will soon find its way into production cars in the future (it has been used in certain racing engines before), although it remains unknown when an official debut will take place.

Campro is better than free valve…
At least every campro evolution theres advancement. Dual VVTi goes backwards and perform worse than 10 year old dinosar!
When is the qoros being introduce in Malaysia
Why it called freevalve..it still have a valve there..its suppost freecamshaft
