It just turned Wednesday June 3 in Thailand: Jan Thiel, Happy 75th Birthday!

Re:30,000 rpm ignition.Multiple pickups would solve that issue,no?2 triggers would make the cdi "see"15,000.

When Frits says simple I thought along the lines of a boost bottle type apparatus but using crankcase pressure on a diaphragm to increase the pressure of the charge in the vessel.Even a mechanically driven diaphragm.

Wobbly was right though in that the most astounding thing is the rpm and how to make the moving parts sustainable. Simple but amazing.

[Frits Overmars]

wobbly just a fast question about that cylinder im welding. would i be better off putting studs in the cylinder and fastening the head on with nuts rather than the original bolts that screw into the cylinder ? wasnt sure if the heat has weakened the threads and they wont hold the 20-25ftlb or so of torque without stripping the threads

Studs are better. If you tighten a head bolt, you generate a tension force in the bolt and a rubbing movement between the male and female threads at the same time. Especially the female thread in the light-alloy cylinder body doesn't like that.
If you use studs, tightening the nuts will put the same tension force in the studs, but at this stage there is no movement between the male thread of the studs and the female thread in the cylinder body any more, so no wear.

Re:30,000 rpm ignition.Multiple pickups would solve that issue, no? 2 triggers would make the cdi "see"15,000.

2 pickups and 2 triggers would give a total of 120.000 pulses per minute. That would really overstrain the CDI.
You could use two CDIs, each with its own pickup, and one trigger on a shaft, running with half the crankshaft rpm (elsewhere known as a camshaft, yuk)
but that would violate the KISS-principle.

Not all shots in the dark hit the mark I guess.And we certainly wouldn't want to resort to backwards thinking 4 stroke technology.....
Happy birthday Jan!!!!!!

Took the Ryger-kart for a little spin today.
God Almighty!

I've got a fairly good idea of what to expect from a 125 cc kart. But this....
The revcounter could hardly keep up with the crankshaft but in any case it revved much higher than a normal 125 and I reached the end of the straight-away much quicker. What a rocketship!

"what a rocketship"...... well, that I recon says it all.... its a rocket engine!!!

Frits, will this engine be produced by Ryger, or will the patent/production rights be sold off to the highest bidder?

And when will it be tied up ( patent ) so we may know whats happening inside? When can you tip that can of worms over for us to sort through?

A free piston engine runs at very high ( rpm? ) oscilations, they have rings and the pistons are subject to high inertia, they work.

[senso]

I dont know what type of ignition is being used, but even using an analog CDI its not too hard to have two separe high voltage coils in the stator charging two independent capacitors and then when there is the trigger you fire one and then the other.
Or having two high voltage coils charging the capacitor and using a single capacitor and firing transistor/SCR.
With a digital its even easier to do that.

I'm not at liberty to answer that.

I can envisage a free piston engine surrounded by coils, acting as a generator and driving an electromotor. But that's for next month.

[husaberg]

If you advance the slider movement by 90° from the present phase, it could run as a two-stroke.
Attainable power would depend on dimensions and revs. The 120 rpm in your picture may be somewhat scanty .

But I had my heart set on maintaining ever detail including the colours...........
It does kind of achieve a more continuous flow than the dirty old crankcase design though, Granted it does also fail miserably on the KISS principal.
Happy birthday Jan.
75 Not out is nearly more than the English team scored at the cricket world Cup.

I did read that, soooo no time frame on a green light yet? Are we there yet, are we there yet, I'll just keep asking

Initially when I heard about this engine ( 30,000 rpm ) I assumed a free piston engine.
You know, a V1 pulse engine with a free piston in the middle ( combustion chamber ) and yuk, the work of the devil, electric drive!

Neil, have a look at this. I can see quite a bit of you in this. https://www.youtube.com/watch?v=fKMLYFVwNVg
There are bigger ones as well.
I'm sure that between you and Wob, who must have around a million old expansion chambers around the back, could join all these up, attach them to the back of a ute. No need for pistons, electric drives, mysteries or 30,000 rpm. Just simple gaseous direct drive. KISS. Out Ryger the Ryger!

[Flettner]

Yer, pistons are so last century, who needs them.
