How does Koenigsegg Camless engine work?
By doing away with the camshaft and replacing it with a compact actuator above each tappet, the Freevalve system allows each valve to be individually controlled. They can be lifted as much or as little as the engine management dictates, for as long or as little as required, as early or as late in the cycle as required.
Are there Camless engines?
A camless 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. This is not the case with the camless engine, where lift and valve timing can be adjusted freely from valve to valve and from cycle to cycle.
What are the benefits of Freevalve?
Freevalve allows for optimal valve times for volumetric efficiency at all RPM’s, plus
- Use of intake runner inertia at all RPMs.
- 100% scavenging of residuals at all speeds and loads.
- Increasing volumetric efficiency.
- Reducing or eliminating knock even with high compression ratios.
What is Freevalve engine?
The Freevalve concept, also known as fully variable valve actuation, offers the unique ability to have independent control of the intake and exhaust valves in an internal combustion engine. This allows a greater degree of control over the engine which in turn provides significant performance benefits.

What engine is in the Koenigsegg Gemera?
Koenigsegg Gemera’s 2.0-Liter Twin-Turbo Freevalve Inline-three Is The ICE Of The Future. The 2.0-liter, twin-turbo, inline-three engine in the Koenigsegg Gemera is what dreams are made of.
Who uses Freevalve?
Christian von Koenigsegg
One key player who strongly believes that is Christian von Koenigsegg, who recently gave the technology a proper push through his team over at Freevalve.
Is Freevalve patented?
Safeguarding value through patents Today, Freevalve has 15-20 patents protected the world over, and there is a constant flow of new inventions for which we are seeking patents,” comments CTO Urban Carlson.
Did Koenigsegg use Ford engines?
Today’s Koenigsegg engines include only about 5 percent Ford engine parts. The Swedish automaker also now produces multiple engines, including naturally aspirated and twin-turbocharged varieties. The Koenigsegg 5.0-liter naturally aspirated V8 engine generates 600 hp; Ford’s 5.0-liter V8 produces 480 hp.
Why is the Koenigsegg illegal in America?
Due to the car’s design and limited production numbers, the Koenigsegg Agera has a retail price of $1.5 million. While owning an Agera in the U.S. is not illegal, the car does not meet certain federal standards. This makes it illegal to drive on American streets.
Is Koenigsegg faster than Bugatti?
Bugatti won its constant performance competition with Koenigsegg, in terms of its maximum speed and time of acceleration to 100 km/h (62 mph). Koenigsegg, however, proved itself better at its highest speeds, and included a more innovative engine construction.
Why are Koenigseggs illegal in the US?
How are cams used in a camless engine?
Instead of using rotating cams that are driven from the engine’s crank to actuate the valves, a camless engine uses air pressure above and below a piston that is connected to the valve to operate it. There are also some examples that use electromagnets to operate the valves, although these are less common.
What kind of valves are in a camless piston engine?
A camless 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.
Why are there no pushrods in a camless engine?
Because camless engines have no camshaft, they may have fewer moving parts. In these systems, the camshaft rollers and pushrods have been replaced by an electro-hydraulic actuator system which uses the existing fuel pumps, thus reducing development risks of the new system by employing existing technology.
Why is a camless engine better than a crankshaft?
Additionally, because there is no chain connection between the crankshaft and the camshaft, the engine is lighter with fewer points of failure. The absence of a camshaft also means that the parasitic load on the engine is lower, which is particularly useful in large marine engines, as it can equate to a large amount of power savings.
