Give me you email, will send some exerts from book. It will be better to run pressurized, due to lower total friction loss -ie 1 bar at 1000 rpm is close to 2 bar at 500 rpm, but latest one have twice lower piston ring friction + aerodynamic losses too.. I did it ran with your current geometry - its...

You welcome. Do you have Senft book on mechanical efficiency of stirling engine ? Changing angle from 90 to 120 or 125 degree is not as hard. For our baby power level - aluminum crankshaft is totally ok. I was able to make new one for my first attempt in one evening turning session. Do you have bear...

Btw - my project was also born from similar china twin 65mm bore air compressor..

This is for 125 angle between expansion and cooling: https://i.imgur.com/qQQUiSW.png Red is force work area then buffer pressure is half mean cycle pre...

And regenerator od id

Working fluid pressurization ? Piston rings one way ?

Turned in lathe to give final touch.

~480 cm2 of area.

Heater cooler tube length, diameter internal and numbers. Regenerator size and fill..

Please provide you geometry data - will make some simulation run for you.

Btw thsi guy was able to make it. https://m.youtube.com/channel/UCe3fCFq8H2cVzbVA-_lzO6Q

Tomorrow happens:

Internal alternator taken from china 250w / 36 volts ebike motor. Plus some space left for extra flywheel.

Newer, newer and newer use ready made equipment for stirling engine. Its just have too much wrong bore/stroke ratio and is too massive for our power level. You cant make re generator shorter than you stroke, and i was forced to have it at 45mm length.. Where all examples and simulations shows 20-25m...

I also did notice this.

Sadi, you a wrong. Alphagamma is nothing more than alpha with bigger than 90deggre phase difference and less parasite load on drive mechanism. And it was builded in more than one prototype. I would not comment you invention.

Hello. I am on 10% of building my firts power producing str engine. Decided to add progress here. It was inspired by Viktor from Russia (He actually try to build engines for sale, based on v twin compressor) : https://en.energotonyka.com/teploelektrostancii-na-othodah https://www.youtube.com/watch?v...
