Manolis / Uniflo
This probably was asked of you before but I'll ask it anyway
Has either of you tried replicating the Honda Activated Radical Combustion technology as seen in EXP2 in any of your projects?
W-F1, FYI, the Evinrude E-TEC DFI outboards utilize a similar auto-ignition scheme for high-efficiency low rpm work..WilliamsF1 wrote:Manolis / Uniflo

Please check the publication number.
The WO207142512(A1) number seems as the publication in the WIPO - PCT of an international application which does not exist.
I checked the name Ryger in the Espacenet . There are 12 documents, none of which fit with Ryger's 2-stroke.
Thanks

Why replicate it when we could do better? I do have a side project running, well it will be in the new year also, that uses a type of HCCI, no spark plug and the ability to change the timing (HCCI ignition point) with RPM and load. COULD be fuel controlled only with the intake being open (not throttled) but this we WILL have to test. It will be interesting.WilliamsF1 wrote:Manolis / Uniflo

That will be something, Uniflow.. AFAIR, Harry Ricardo tried to achieve this with his R-R Crecy research mill, many moons ago..uniflow wrote: Why replicate it when we could do better?

this has been puzzling me ....uniflow wrote: .... Autoflight 700 twin, designed for aviation use. Water cooed, case reed, internal gear reduction. Uses a balance shaft. This is the prototype, two more engines are now available for test. New engines have the balance shaft internal, water pump in a different place, electric start. Future development to become semi direct injection with oil less top end, all proven technology, just needs to be applied.
EDITED HERE - to correct my original wrong explanationmanolis wrote:An even firing 2-stroke parallel twin (crankpins at 0 and 180 degrees) needs a first order counter-rotating balance shaft to counter the – otherwise – strong inertia moment.
First order means that its speed equals to the crankshaft speed.
Counter-rotating relative to the crankshaft.
The height the balance shaft is arranged is not important (you can put it under the crankshaft, or at the side of the crankshaft or even above the cylinder head).
