29 May If you thought the internal combustion engine was on its way out, think again!. 30 Jan Lightweight, low-cost and generating low friction, FreeValve engine concept functions without camshafts and allows valves to open and close. 21 Nov This is a discussion on Koenigsegg’s camless engine within Technical Stuff, part of the Under the Hood category; The future is here gentlemen.

The first thing everybody frets about with such systems or with an old car overdue for a new timing belt is what happens if the valves go out of sync and try to stay open when the piston is rising. I believe the last major advancement was the Ecoboost engine which could fit on a A4 paper. Last edited by Sutripta: MAN has had a camless engine on the market for many years.
Koenigsegg’s camless engine Valves are still related to engine revolutions, piston position etc.
Is the Era of the Camless Valvetrain Finally Upon us?- Technologue – Motor Trend
In the Spring ofChristian von Koenigsegg told reporters that the technology pursued by his company is “getting ready for fruition”, but said nothing specific about his company’s timetable.
Not exactly an apples to apples comparison.
Camless Engines – The Next Big Thing?
Overall emissions are said to be reduced significantly as well. The latest and most promising of ‘camless’ designs has been showcased in camoess Qoros 3 GT development car. FreeValve claims the results are revolutionary. What does a camless engine use instead of a camshaft?
Last edited by GTO: These marine container ship engines are 2 stroke diesels, are about the size of a 4 story building and redline at rpm. But M ller notes that “a combustion chamber designed from scratch with the Freevalve system is likely to have a higher compression ratio [allowing valve timing to reduce effective compression] and a smaller area-to-volume ratio with more upright valves that are less prone to bending in cqmless of piston contact.
Camless piston engine – Wikipedia
Every such efficiency-boosting miracle like enine further delays the demise of the combustion engine. Easier said then done. Because the engine recovered braking energy as compressed air, that energy source was abundantly available.
Actually, not much, explains Freevalve marketing director Andreas M ller: The following BHPian Thanks samcan for this useful post: Icon adds electric powertrain to Fiat Another 15 manufacturers have expressed interest in the concept. A famless or free-valve piston engine is an engine that has poppet valves operated by means of electromagnetic, hydraulic, or pneumatic actuators instead of conventional cams.
Koenigsegg’s camless engine
Four-Rotary Icons at Laguna Seca. For decades the idea of electronically controlled electromagnetic, hydraulic, or pneumatic valve actuation fngine been studied, developed, and ultimately abandoned by big-name engineering firms such as Lotus and Ricardo—as well as familiar automakers including BMWFiat, FordGM, and Renault.
Actuators can be used to both open and close valves, or to open valves closed by springs or other means.

Perhaps more important, the engine’s power improved by 45 percent, torque by 47 percent, and fuel consumption by about 14 percent at steady highway speeds. The next big innovation for internal combustion engines in cars will be removing the camshaft altogether!
Koenigsegg’s camless engine Though this camless engine technology sounds very interesting to me, I am just thinking how the timings of both intake and exhaust valves would be taken care of. All for the sake of reducing emissions from the internal combustion engine.
For one, the system is still undergoing real-world trials. Interested in bike loan offers? But even today after so many years, don’t the turbo fitted engines I am not talking about supercharged engines suffer lag below certain RPM?
Now a spinoff of hypercar maker Koenigsegg called Freevalve appears poised to bring the concept to production.
