| It seems OK whith the mysterious ring located at the cylinder base of Ryger engine, and some of comments: "Works similar to a compressor layout". Very nice Dan |

| didn't Frits say on Kiwi-biker that we would see nothing out of the ordinary looking through the exhaust port ?
sure it was with the piston in BDC, but don't remember if it's true if the piston was at TDC. |

| If this is actually the patent, there is a sort of slide at the front of the upper piston that covers the exhaust port at TDC, so you would see only what appears to be a piston.
I suspect RYGER is from Hendrick "HarRY") GERrits. Time will tell... |

| This design seems to solve the 2T émissions problems: séparate crankcase, no oil mix. The succion chamber is smaller than the cylider capacity, not good for high power output? There are probably mixes between fresh and exhaust gazes ( good for emissions, complete combustion??). Scavenging is certainely very good, is there a good effect to push the piston up during compression stroke, due to the close casing? And we suppose that design works thery well with a big bore/short stroke layout ( remember the Ryger revs 125cc: 17000 rpm and up, 30000 rpm in correct dimensions). Very nice ![[2stroke] Ryger engine 241515](/users/3313/47/10/07/smiles/241515.gif) Dan |

| You could also notice the short length of the conrod 90mm which also, mean light! and the volume of the "combution chamber" 11cc. And if the design is quite close of the drawing , which come from a draft of patent( the arrows which design the different parts are tipically the ones we use on patents) i am quite sure that at least one transfert pass through the crankcase, this one could be use as a "breather" for the cranckcase and maybe that's why not 0% of oil emission.

the Ryger is designed and developped by Ryger, not by Frits. Frits has next to nothing to do with it (I believe). |

only 2 rings (look at the homologation) and it runs a lot cooler tnx to the HCCI ignition (very fast burning so there is less time for metal to heat up). |

| I was refering to the drawings from the patent. I was aware that the homologation stated that only two rings where used. Hopefuly they will wait not much longer with showing what this enigma realy is. |

Or how does it work exactly ? ![[2stroke] Ryger engine 55116](/users/3313/47/10/07/smiles/55116.gif) What does Mr. Jan Thiel construction for the Ryger ? ![[2stroke] Ryger engine 167764023](/users/3313/47/10/07/smiles/167764023.jpg) Regards Zar |

| I have absolutely nothing to do with it.
And I would have to see a powercurve before I believe any 125cc engine gives
70HP and revs to 30.000!

| I understand that piston has 2 rings ( one on the upper piston part and one on the lower skirt) and 2 lubricating grooves on each piston parts ( oil distributors). Concerning the 11 tranferts it seems there are 8 in the main base flange ( controled by ring valves) and probably 3 in the cylinder ( 8+3=11). The exhaust port appears in very high location in the cylinder, but the drawings are certainely not at the good scale. This good subject will be in a better Post: "a better two stroke" yes or not?

Pierre Yes, i understand that "the recess" in the base ring/flange is the "breather" or the door. ![[2stroke] Ryger engine 809262](/users/3313/47/10/07/smiles/809262.gif) Incredible engine with control valves transfert. Dan |
