  • "Freevalve" camshaftless engine tech.

    Got a blurb today in my Google Feed about the forthcoming "affordable" Koenigsegg "production" automobile. Of course, affordable means different things to different people. They're talking 600,000 to 800,000 euro, and a couple of hundred cars per year. Oh well.

    But the interesting thing to me was a mention of Koenigsegg's "Freevalve" engine. Hadn't heard about that before, so I googled and found a couple of interesting links. Pneumatically actuated valves, rather than camshaft activated. Technology used in F1, but this appears far simpler and less expensive. The ICE isn't dead yet, I don't think. Here it is in a video:



    A status update, and some more details, here:



    And for those who like to read, a somewhat more detailed article here: https://www.motortrend.com/news/is-t...s-technologue/

    Or have Jason Fenske of Engineering Explained do exactly that:

    They say that it shrinks the external diminsions of the engine and extends milage per gallon. Several years ago I read that GM was looking at it.

      I am sure that it will be an excellent system, that is if it meets long term durability standards. Whether it will extend beyond Konigsegg in the near future is of course unknown. Am I not correct, that even Konigsegg has yet to produce its first customer car with this advancement?

      I think all issues will be eventually figured out, and it will again add to the longevity of the internal combustion motor, but its use in large scale OEM motors is, IMO, more than a couple of years out.

        Not really related but an interesting segment on if the ICE will survive.

          This is such an awesome innovation, going to be awesome to swap motors with this tech into older cars someday!
