your three ring system looks interesting. it will definitly give a lot of ring movement/ conformity so should stop any thermal expansion problems. do you put the two open ends of the piston rings 180 degress apart and what stops the rings from rotating in there grooves and hence lining up the two cu...

Your engine looks excellently made, if it performs as well as it looks then you have a little cracker! Did you have the expansion slots wire cut? When I have used thin stainless steel shim as a regenerator, I indent dimples into the surface with a seamtresses spiked wheel (what they use to make pape...

in a previous reply you mentioned that you are using a three ring system with spring preload. Can you please give more information on how this works as i don't think i have come across it before. I have been using a combination of either lip seal or normal Rulon pston ring but with a over lapping jo...

It does look like you had some choking inyour transfer pipes, as now with more surface area you acheived 20% more power. What is the reason for using different materials for your expansion and compression cylinders? Have you experienced problems with thermal expansion and binding of the piston/displ...

very nice engine :razz: . I am very interested in the effects of altering volume ratios and phase on engine performance. What volume ratio are you using for your engine? and have you had any experience using a different value? If you have, what effect did it have on engine performance? What material...
