Electronic Valves Coming To Jaguar?

Electronic Valves Coming To Jaguar?
Apparently much of the testing for this technology has been going on with Jaguar engines, however it also says Asia will likely get the first implementation of this tech. But fascinating technology, particularly fascinated that you can go from 4 stroke to 2 stroke to 12 stroke (economy rotating the dead cylinders to prevent problems). https://newatlas.com/camcon-digital-...0possibilities
Oh a decent pop in performance and efficiency as well.

The 12-stroke mode is pretty interesting. Once you mechanically decouple the valves from the crankshaft you can do things like fire on every third crankshaft rotation. I'd be interested in how various failure modes are handled, i.e. can it be made "non-interference" on failure of one of the cam motors?

As a classic Mercedes collector, these words put fear into my heart. You have no idea how problematic every single implementation, no matter what its function, up to date. If it is pneumatic, it means it leaks in a dry climate, doesn't work well in high humidity environment, has constant issues with a pump...
I hope they reconsider and go with an electric solution. I will risk interference hit over dealing with pneumatic system.

elecro controlled pneumatic actuation.sCamcon system uses electronic control of electric motor driven desmodromic individual cam per valve.

Guys, as a retired patent examiner I can say : as often before, whats presented as new, already exists somewhere else... As it does in this case..
But the original works with 'batteries' pumped up by a camshaft. Only the timing is done by the ECU...
This latest development replaces the ' cams/batteries' with a single central pump.. .. not inventive to my opinion, but hey : I'm retired..
The principle was patented by FIAT in 2002, as the Multiair system..
This was licensed to a German company who fine tuned the system and named it
[ brush up your Spanish.. ].
..and made the Ingenium engines work for JLR, like in my P300 ...
.. Multiair is fitted in my 2011 Alfa Romeo Centenario 1.4T....
SO NOTHING TO SHOUT ABOUT...

Then we have the 'old lady' , the family car , LR3 TdV6 , and my P300...
Next car is a D5 or F-Pace V6 diesel... ... waiting for the lottery numbers to fall in line..
