Camless Engines – The Next Big Thing?
Christian Koenigsegg also claims that the PHEA camless technology allows the elimination of the pre-catalytic converter, because the standard catalytic converter can be brought up to temperature quickly by manipulating the exhaust cycle. Though electronics might pitch in to do similar work, will it be that accurate? When was the last time you experienced or heard of a camshaft 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.
For a boutique car company like Koenigsegg, it makes sense. I understand that with this solution you can do away with the timing gear. The future is here gentlemen!!! What if the driver puts the pedal to the metal suddenly? Easier said then done. The tech will roll onto the stage in the 1. Fuel injection can shut off when there is sufficient pressure and add more fuel when there is less pressure allowing the engines to run closer to a perfect diesel cycle.
We value your privacy. But that was then, since then. 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. Select a Year GO. Another 15 manufacturers have expressed interest in the concept.
The time now is MAN has had a camless engine on the market for many years. Originally Posted by emgine The concept of turbo was introduced to increase the power without having to increase the cubic capacity of an engine.
Is the Era of the Camless Valvetrain Finally Upon us?- Technologue – Motor Trend
What could be the problem? Each individual valve is controlled by an actuator, powered either electromagnetically, hydraulically or pneumatically.
Get online loan approved in 3 min. With the changing opinions of governments and people, these companies would also find more support for it. The engine relies on pneumatic valve actuators to open valves, which are then closed by air pressure or springs. In the modern age of the car, it is one of the few components which is more or less fully mechanical, unlike other parts which are increasingly being controlled digitally.
An engine with it would have infinitely variable valve timing, including being able to completely shut them for cylinder deactivation.
Camcon also discussed features and camess in an czmless and video that was published in Autocar magazine  “New Valve Technology gives Petrols the Efficiency of Diesels”.
The latest and most promising of ‘camless’ designs has been showcased in the Qoros 3 GT development car. Photo Gallery 3 Photos in this Gallery. Valves need not close and open with engine revolutions. Mazda Historic Enginw Cars: 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. And the youtube Drive series is always a great watch.
But now, Koenigsegg’s sister company, Freevalve, has come out with a technology that removes the traditional CAM drive. Camshafts normally have one lobe per valve, with a fixed valve duration and lift. Reciprocating engines and configurations. Most Popular This Week.
Interested in dealer callback? For decades the idea of electronically controlled electromagnetic, hydraulic, or pneumatic valve actuation has 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.
Mostly because there have been few viable alternatives for it. Camless engine was invented probably 25 years ago and has been in the lab ever since waiting for cost of hydraulics and other components to drop The problem with that is the camshaft that we know of today is simple and works so beautifully for what it costs with fantastic reliability.
