    I'll let you know as soon as I get the green light Neil (what's the english word for this kind of approach: recursivity or recursion?)

    Would the FOS concept, if it were fitted on the Ryger engine, be better or worse? Gas flow wise.
    We are certainly going to test the combination. But like I said the other day, I've become careful; I'd rather not announce expectations but wait until we get results.

    Frits, have you found a way to control your fos barrels transfer and exhaust ports then? sleeve or reeds or gas pressures?

    Thank you Frits,
    It's a bit awkward looking for stuff being on the other side of the world.

    Probably recursion, but "Catch 22" is better.

    I think the 15hp at 15k is a bit of a ruse. A rotary conversion, and 18+hp

    I think I know what you wish to hear. The laws of physics haven't changed but I am beginning to realize that I neglected some aspects of the gas dynamics in an engine as being unimportant, until Harry Ryger showed what can still be found there. I'd really love to be more specific, but that will have to wait until I get the green light.
    Frits, pulling your leg, nah, don't want to see you fall over, you're a great source of info and inspiration.

    If it relies on gas dynamics, then does it start easily at low speeds with no positive mechanical displacer for the incoming gas (or air) only?

    He was the one doing the beautiful RSA like Cylinders but alas his site seems to no longer have them or the other Honda conversion stuff.
    he has this test bench listed but I can't figure it out .

    It looks like an engine dyno

    Gee thanks Mike, But what does it drive to measure the output.

    edit I google transdutchrelatered the text
    looks like its an inertia one only minus its flywheel.

    This test bench is used by us to test engines oavoor karts . This bank is completely finished on a flywheel and after the necessary software. (Supplied by Rotec Yselmuiden www.roteg.nl )

    All materials are provided. Motorbikes can be mounted on an adjustable carriage . The drive goes through the motor output shaft to an intermediate shaft which in turn drives the large main axis at the bottom of the bank to this should be so to place a flywheel .

    Complete with cooling water pump and radiator hoses , circuitry, temperature gauge, gas and clutch cable programs. Everything is little used all bearings are of the best quality

    I happened to notice this addition to your original post, Neil. Normally I would have missed it. And I hate missing things, so from my point of view it would have been safer to put it in a new post instead of adding it to a post that I already thought I'd seen. Come to think of it: God knows how many valuable additions I've already missed because I usually don't go back to 'old' posts.
    That Husqvarna video of yours reminds me of a Stihl patent ( http://www.google.com/patents/US6415...roke+OR+engine ) wherein scavenging is also taken care of by air only, after which the fuel-air mixture is transferred. But I don't see any similarities with the Ryger engine.

    I never planned to control the exhaust ports. We talked about controlling the transfer ports here (via the 'commas') but once Flettner showed an interest, I thankfully turned my mind to other (Ryger) things.

    It may be just my suspicious mind, but do I feel a hand on my leg again?

    It starts like any other kart engine. You get a push, you knock the shift lever into second gear and off you go. And I don't need to tell you that any conventional two-stroke is started with the help of a positive mechanical displacer for the incoming gas or air: the crankcase pump. That's all I can say right now.
