Because a camless engine has fewer moving parts, there is less friction. to mass production of FreeValve technology is also a first baby step. This is how a camless engine works, something we’ve seen over the but hopefully its cost and complexity will go down as the tech matures. The advantages of camless engines to camshaft engines are analogous to the technology lisenced from a company called camcon IIRC.

Where are all the Camless Engines?

WRT keeping the valves open to deactivate cylinders: This would also eliminate some of the other rpm limitations and accuracy shortcomings inherent in the reciprocating valve system. Camless two stroke main propulsion engine. Urp ok after looking at cutaways online, fuel injectors are not THAT small.

This is due primarily rechnology section 5.

Camless piston engine – Wikipedia

Poor English translation, possibly an automatic translator output Please help camlesx this article if you can. Every such efficiency-boosting miracle like this further delays the demise of the combustion engine. Running without oil is bad for any sort of engine. Just consider the frequencies involved and it is clear this is a whole other domain. Sorry hit the report button by mistake.

Not all that loud, Harleys are louder than the puch but at the same time I never heard myself at 55mph from a distance technnology is like having a wood sander between your legs at that speed: The engine control unit ECU fires the injectors at just techhology right time to inject fuel into the cylinders. Pretty much what I expect from you though- professing an opinion on something you know nothing about beyond repeating what you have heard from the equally clueless.


Now… The valve lifter: The best effort to date has been from Freevalve, a subsidiary of Koenigsegg. Others, such as the cam-in-block design, are more complex, with pushrods, rockers, and other parts required to translate the movement of the cam lobe to movement at the tecchnology.

The system consumes oil and is very unpredictable under certain stress conditions. Once electricity is disconnected, the core may still be moving due to its inertial mass.

That number is close to double when holding the valve open. Camless valve actuation and variable valve timing schemes have been batted about just about forever. Any time canless progress makes the cars too quick and therefore dangerousthey add some arbitrary artificial limitation. F1 is massively regulated in terms of what they can do.

And then your electronics fail and ram your valves into your piston, because non-interference designs are highly inefficient and impractical. In addition forces are much, much larger than in a fluid control valve. Who in their right mind makes an intrusive valve technokogy using a Kevlar belt? Frank Markus January 27, Conventional light bulbs are relatively simple devices- a bit of glass formed in one simple step, a bit of filament and a conductive metal cap… CCFLS?


At the core, a fuel injector is a solenoid controlled valve. Engine damage is implied. And then your poston moves upwards, trying to push all that stuff out.

The advantage of a camless engine would be true variable valve timing — the gains would be similar to modern VVT systems but more dramatic. It also allows multiple lift events per cycle and, indeed, no events per cycle—switching off the cylinder entirely.

To meet thees standards the mass of the vehicle must be reduced as much as possible.

The photo above showing the 2 timing chains on that engine… one of the high end Dodge now RAM pickup engines has 3 timing chains, a failure of any one of them munches a lot of components. Suprised the author missed this.

Wait long enough, and Moore’s Law of increased computing power in smaller packages or just good ol’ human ingenuity eventually makes all great ideas practical. This page was last edited on 18 Novemberat The results are myriad technollgy solutions.
