maybe this is where a breakthrough has been achieved in controlling the hcci .

Conventional combustion is just fine, i guess. Remember, Frits said the Ryger was simple, and controlling HCCI is definitely not.

But I hope we'll know more some time soon - are there any homologation papers online, as of yet?

F1 mills have toned down the rpm since going high-pressure forced induction for power instead, but lazy N/A 4Ts really have to rev
..

Not true. They were regulated to 18000rpm by the rule makers (in the v8 era around 2008ish) in an effort to keep the costs down. The BMW was spinning to 22000rpm. The manufacturers all said 18000 to 20000rpm was easy, it was the last couple of thousand rpm's that cost the most money.

I've made a few, not on purpose though...

Ha Ha, me too I have a shelf of piston shame.

I use a 5mm diameter carbide ball to do the rear wall hook on the Aux ports - this makes it easy to see how deep the outer wall is going.

Re the Ryger homologation papers.
They have been approved by Rygers local ASN ( country association ) to be forwarded to the CIK to go thru the homologation process.
This includes sighting of the completed engines and requisite spare parts catalogue.
I have access to the CIK site area that holds the applications but until the formal procedure has been completed, no one can actually
see the papers until they have been stamped as approved.
All we can do is wait - there is even now alot of speculation and disbelief by current manufacturers like TM that Rygers claims are valid.
Unfortunately for them when the Ryger is approved for use in karting it means all other products will be redundant with the stroke of a rubber stamp, and 2T technology will have been
advanced beyond anyone's wildest dreams.

I don't know i have a pretty vivid imagination Wayne.

There was a comment on their farcebook page saying they were now working on a 250 twin, with their own crankcases.

If the Ryger uses a separate charging "pump" to intake the air or air/petrol mix and push it into the cylinder, as seems almost a given, then the Kart authorities might have concerns regarding the ratio of "in' to "out", i.e. Looks like it could be easily supercharged, with detection thereof very difficult.

Is true.. boost in F1 now means those high teen rpm figures are long since passe'..
& of course the diminishing marginal returns of port-time-area/friction/cost was indeed, crushing.. Honda tried to beat it & failed - with their NR500 4T.. 30+ years ago..

One leaver arm, one con rod, one hydrodynamic short stroke crankshaft and two guided pistons?? Imagine that.
Either way, now we are talking, 140HP for how much weight? Not much!

Brilliant.. Bring back Buck.. ah, I mean..

Bring back real bikes, 2Ts - to G.P. racing!

The result is true. The time line you described is not.

[J.A.W.]

Yes it is.. rpm limits are way lower - particularly so, since F1 went turbo-compound & Moto GP dropped the 800s..

& you can't quote me on any such thing as a "time line" -so you ping me with a red rep point.. thats piss weak mate..

With these karting rules, is there a requirement for a kill switch?
If the Ryger is running HCCI ( auto ignition ) how the hell do you turn it off if the engine gets away on you? Assuming a stuck throttle say.
Turn the fuel off and wait? Fire extinguisher up it's carby?

i've had that happen - by accident...plating flaking off a surface gap plug turned it into an ignition source.
Other than stalling it - if you realise in time - it's wait for the fuel to run out.
personally, I'd doubt if the Ryger uses HCCI.
