Exactly, that's what I could do without closed crankcase design. It is 5 inch cylinder by 12 inch stoke, you figured out the diameter size right on. I only use 6" of the 12" stoke movement and rest of the extra space for larger port openings and rod support. I will fill in extra space insi...

Yes, both sides of the piston are to be pressurized. I ran some tests on the power piston with total pressure differential up to 25 PSI, when the "crankcase" was at 150 PSI initially. I measured output stoke of about 485 pounds of force (steady). The engine is not complete at this point, j...

Yes, it would be based on Jim Symanski's 2.5HP wood-fired gramma stirling engine. The whole thing will be pressurized with 150 PSI or so, with only the atmosphere pressure pulling the piston rod out, will depend on how big the rod diameter it is. The atmosphere pressure will have little impact in th...

I am new here and I am very interested in this topic but for a different reason I believe Jim Symanski's 2.5 Hp wood fired gamma employs this: http://www.starspin.com/stirlings/jimd6.html He uses 2 displacer units which alternate cycles. but are both heated by the same heat source. They are piped i...
