DIY STIRLING ENGINE Update Air Compressor to Solar Stirling Engine

This is an update on the progress of the Stirling Engine created from a standard air compressor. This hot air engine should finally get some power. The piston rings were removed as the machining of the pistons was very good. There is still good compression. The ring removal decreases friction dramatically and will allow for a good cycle. The Displacer is a Bikini Spray can that I got to fit perfectly. At the end is the ghost of Robert Stirling. Just kidding, think I have been working too hard.

Okay, so you have made a video before with a sirling. The earlier engine has water cooling and welded construction. this video has a plywood flywheel and an areosol can displacer. That tells me you really don’t have the knolwedge or the tools to make this compressor engine work. Do you even know what configuation typel it is? What will you delta T be? What about thermal conduction through the block? There are good reasons why others have been unsucessful using off the shelf compressors.
@muddymuddymuddmann Silicone gasket,, the red stuff:-). I need a machinist, this is tricky to seal, close with the prototype resin blocks. Displacer cover is very nice fit 1/8″ tolerance or less.

Nice trick for going from alfa to gamma. I worry about the internal frictions in the crank.
Try an aluminum bolt and the rtv or epoxy.

What about using rare earth magnet covered in ferro-fluid seal made from laser printer toner and a little oil. I’ve seen it used in acoustic type Sterling and it looked gastight yet low friction. Just wondering if it could be scaled up to your Sterling? The rare earth magnets would have to be cast in resin to make a double lipped disc where the ferro-fluid could sit between and seal the cyinder/piston.
So from this point push the piston all the way down in to the block,and add another can to it a big ,coffie can, or tin and fit it inside a peice of stove pipe. seal the stove pipe,at the bottom, with rope to fit the can,the rope from a wood stove door.
now! heat the black steel stove pipe,and seal the whole thing with JB weld! it won’t burn! That is a simple fix,and cheap, it should make your stirling run too! I promise! Tey are all about Volume of air!
Yu can put a second tin around the bottom of the stove pipe and jb weld it in place,fill it with water, then that’s about perfect.
thanks,dan rojas
keep it up
your practical idea inspire a lot technical people.
im sorry,im not fluent in english
@glotoniok Thank you:-)
nice,i saw this before,mr.dan rojas
good works
keep it up
i hope your going to replace those piston rings, you’ll want to run this at pressure or your power output will be even less than it looks set to be.
what is the dia of the piston? will you use Teflon Piston rings? what will be the working gas? i think it will not run on simple air. Hydrogen will b the best.
@rptopf I hope u will be.
Good JOb!
How is going so far ? I hope its running soon!:]
Great work !
does a piston works instead of the spray bottle?
So!
Now that you have a small one of like size, and bore,proportionaly any how,”the new one” Will you try again to make a same nature pattern of this one!?
Now you have 2 flounges .perfect to fit cooloing and heating chambers on it.and to connect both chambers with cappilar tube from any refrigerator (cooper).
as for bikini spray ))) i do not know what it is doing inside of cyliner liner))
Question that might have already been asked, but I’ll ask it anyhow.
Are the pistons at 90 degrees ? it is my experiance with pumps that the pistons are at 180 degrees.

YYYEEEEEHAAAAH
I cant wait for that two p uh two cylinder stirling…
Solar panels work and good. This comressor stirling is not a good idea.
@88888ralph I was wondering the same thing……Please respond
Hi Dan, From the series it appears that on this particular engine you have mixed an inherently Alpha engine with a Beta displacer. Could this not be a part of the problem you are experiencing?
for some reason at the first 5 second i got turned on
seal that hole with aluma-weld!!!
Dan one small suggestion the copper tube you have connecting the two cylinders .I made that out of one inch pipe and heated that. seems to work very well.it does require a lot of heat. good luck. dg
