You are really one of the most iventive I ever got to "know".
The design looks a bit like the chinese design, but I think your intake port could be more succesful at least at small engine sizes by getting a better mixture of fuel and air.
I don't know, but perhaps jou get some trouble with the intake air entering at the lip section of the can, PERHAPS. I would place the intake a few milimeters more to the CC, entering just or partial mostly behind the lip.
Nice work! Looks good!
Thank you. My gut feel is that the area you're talking about there is fairly critical. Here's why I think this location is an improvement over the original Elektra I design:
First, with this one, we're operating in a region where the flow is almost fully accelerated, and the excess static pressure is almost fully expanded away. That means we should get very little 'leakage' out through the intake. Obviously, it would be advantageous for the next intake charge to be merely at a standstill until the pressure drops, rather than displaced with hot gas flowing outward.
Second, I really see a lot of value in the intake flow being 'sheared' and roughened up by this kind of 'pinched' flow forward into the chamber. That should be really good for mixing and braking of the forward flow, which should give us a good setup for the next explosion.
And, the intake acting as a 'pinch' in the tailpipe should give a little better compression than a fully unhindered pipe. I think this is what Mike E was getting at in one of his suggestions re the Elektra I.
I think the action of the Elektra I, as built, is that of a crudely formed Lockwood [i.e. lots of exhaust out through the intake], which was not what I intended. The new design should come a lot closer to real 'Reynst pattern' breathing, which is what I'm really after.
Anyway, one of these days, we'll see.
