Stirling Engine

Gamma type stirling made of old compressor fired with wood coal.

What's the relation between your displacer swept volume and the piston swept volume?

[24max]

@PedraumF about 1.5 bigger displacer volume than power pistons

Great engine! Did you need to alter the compressor at all to reduce friction?

Ive got 3 old compressors in the workshop, and would like to do something similar.

[24max]

Theres no piston rings, oilring groove have been filled with plastic padding to use the piston skirt as a seal allso. No friction allowed when theres a few wats power... Little leakage is better than any friction.

[24max]

I believe there should be much larger heat exchange surfaces with bigger temperature differences to use better gases and bigger pressures? Othervice hot parts gets cold and cold parts hot and engine would not rotate...

[24max]

few wats, I quess... Just a toy.

I love that sweet sound!

Just one more question... what's the distance in mm between the displacer and the cylinder wall?

[PedraumF]

@24max

I'm building a piston-displacer engine, with a compressor too, but with a V arrangement, using the original crankshaft and rod for the displacer.

I'm a bit confused as we find engines with displacers from 1.5 to 20 times bigger than the power piston. I'm thinking on something about 8 times bigger. By the way, thanks a lot =)

if you could get it to seal right, you could fill the engine with a low-pressure atmosphere of hydrogen or helium and possibly make it more efficient because they are both much more efficient conductors of heat than air.
