See ya later camshafts,

Freevalve system incoming.

This screams of so much win.

I wish to invest. I can see this being the next big advancement in all engines!

Watched a lot of Koenigsegg's videos and this is no different, awesome stuff. No more cambelts for cars or cam chains, valve clearances, smaller, lighter more powerful engines. Imagine.

One slightly pessimistic thing to note is Koenigsegg hand built their own system (just like everything else) on a probably limitless budget - hence no faults over 60,000km or however many they drove their saab. Once the other companies get hold of it their accountants will gleefully shave off 95% of the cost and reliability issues will doubtlessly arise.

At least four years before its in a Koenigsegg though, and probably many more before it's implemented into run of the mill cars, and many more still before it's implemented into motobikes

Still, good post

Very cool!!! It will never get out of spec - no more expensive valve checks and adjustments for those who can't be arsed.

No camshafts or chains to get slack and start knocking. It's so cool.

How do they know how to time it properly though? Is it through the ECU that knows where the pistons are so knows what valves to open? It's probably blaringly obvious that it's that.

To be honest I see mass adoption of electric cars happening before this technology makes it to the average family car in the street.

If this is such a good system. Why another 3 years before it might be seen in any car.....

I'm sure if it was that good. One of the big boys would be onto this and have it running in no time given the mooted savings. Not only fuel wise but also weight/space wise for a new breed of super mini's.
The shear cost savings in manufacture would soon outweigh the development costs.

Odds on this is never seen in a mass production car.

Isn't it similar to the systems F1 cars have been running for many years?

Looks cool. I'd love to see it in a motorcycle engine.

Pneumatic valve tech will trickle through to production engines, probably within the next generation. GP motorcycle have been using it for the last three years. I can see infinite possibilities, completely variable valve timing, power losses from the camshaft / valve spring group eliminated, completely even cylinder filling on all cylinders rather than the differences from non asymmetric shim wear. Engines not much taller than an equivalent 2 stroke, whats not to like?

There will be concerns that the air compressor and associated systems are reliable and up to the job, but that is the only part of the system that has not been tested in a production vehicle as yet, the computing power is fairly minimal. Bring it on..Please, I'm sick to death of juggling cams and shims.

The bit that confuses me is why this is taking so long. The technology is essentially the same as used in fuel injection, just scaled up.

There will be the same nay-saying over reliability and over-complication, but how many people would really choose a carb over FI on a new vehicle?

My suspicion is that the mass marques could do this tomorrow, and probably have it sitting in their back pocket waiting for some big market to mandate efficiency or emissions regulations that will require them to roll it out.

I also wonder why no one is doing throttleless engines for bikes yet? BMW's valve tronic and Fiat's Multair seem to work very well by using adjustable valve lift instead of a throttle plate in the inlet.

Will we soon see FSI/GDI style direct injection on bike engines too?

[stevo as b4]

Are you sure you don't mean Vanos?

Maybe they called it something else then, but BMW have made petrol car engines with no throttle body, and they rely entirely on controlling the amount of valve lift to regulate engine speed, the main advantage like a diesel is much reduced pumping loses.

It could go deeper into block design, no need for a "head" and associated gaskets etc... Block could theoretically be one piece plus sump and top valve cover bolt on.
