I really like this simple design that avoids the need for finely machined piston/cylinder assemblies. . It would also be easy to upscale to bigger components, and to create a multicylinder engine with this approach. Well done!! I am going to start looking for a serious length of steel pipe and a car tyre tube.
Guess the dimensions from the size of the aerosol can and where the crankshaft is placed. Have a go at cutting up a few aerosol cans. They ain't expensive round these here parts.
Hi LS, Great channel, cool projects and demonstrations. From a long time sub, Thank you for your knowledge, time and effort making your videos. I have learned a great deal. Watching in Oregon, USA. All the best, C.
A Holley carburetor vacuum secondary diaphragm works great for the cold piston, versus balloons or rubber glove material. Not cheap, but I’ve got several just sitting there.
@@ludicscience a large flat steel washer with a 2” diameter center hole will clamp the Holley secondary diaphragm onto the bottom of a small 10 ounce steel coffee can. Could easily be incorporated into your designs, and it’s a viable, replaceable part.
@@ludicscience I’m building the Stirling engine, & I came up with a great idea!!! I have an old carburetor system from an old 8 HP Briggs & Stratton gas engine. I sealed everything with silicone, but I left the throttle operational. The diaphragm will be just inside the round air cleaner with the operating rod out the top. Properly positioned, the throttle will actually affect engine RPM., restricting flow from the displacer piston.
realy like you chanel, i made one similar but i put a baloon and fixed baffle and wool at the bottom kinda thermoacoustic displacer. runs fast. thanks for sharing.
I think I will have to keep on & get the crankshaft straight, simply making with a series of bends. It would be more likely for me to get it straight & true than to make those attachment points hold.
Make another one, but this time add a crank to one of the wheels with a magnet that goes through some wire coils and measure the voltage you get out of it.
Have you thought about trying to measure the power output? Possibly by connecting it to some measurable load. If you could also measure the power put in as heat then you can calculate the efficiency.
Lovely project but I think you could have shown and explained how you heated and cooled the air in the cylinder , I gathered from the comments , nevertheless great project , will try it!
I don't know if you are still active or not but would you mind explaining how the stirling engine works and why the steel wool also needs to go up and down? Like does the steel wool go up when its hot and push the crankshaft or does it just act as a piston? If it just acts as a piston, can I use any other object of the same size?
The steel wool is the loosely fitting displayer piston to move the air around and at the same time it works as a regenerator, keeping the hot and cold side better isolated.
Stirling cycle is based on a pressure change, hot end (high pressure) cold end (low pressure) there is a displacer inside the CAN. The CAN is a sealed which is IMPORTANT. The displacer moves from TOP to BOTTOM of the can. It literally "displaces" the air, so the air moves locations from TOP to BOTTOM, at the TOP the air cools => low pressure at the BOTTOM the air is heated => High pressure. Since the can is sealed those pressure changes drive the balloon or diaphragm in and out, a mechanical linkage connects the diaphragm to the displacer in such a way that the cycle continues . So No exhaust, if a leak exists it would simple lower the performance of the engine.
It is powered by the difference in temperature between top and bottom. In this case handle heats and water cools. Air inside expands and contracts moving the piston
KTProjects yea the water isn’t 100% critical but it works on a temperature difference so water keeps it cooler so it’s more efficient and will run longer as the top won’t heat up
Bonjour. L'assemblage des bielles sur le villebrequin n'est pas montré de manière précise c'est très dommage ! Salutations. Un ancien professeur de mécanique de la vieille école !
Note that the position of the 'baloon piston' is 90 degrees (quadrature) to the wire wool displacer, so that the connection to the crankshaft is simple. both piston rods connect at the same point.

This is an atmospheric pressure Stirling - they don't produce a lot of power. However, I'd be interested in mounting a magnet on the power piston shave and wrapping a coil of wire around that PVC pipe, and seeing what kind of current I could draw from it. If you sealed this up better and put pressurized helium in it, then you'd be able to get more power from it.
some info. at 6:13, the mass and its distribution, in each flywheel are Not optimal/effective. at 7:06, imo, the diaphragm is excessively noisy; and this suggests inefficiency. it is understood that different cold-side designs have differing noise levels. ideally, a diaphragm should act as an airtight, low-tension, centering spring; note that where the linkage connects to it, the diaphragm is LIMP. in other words, No centering affect is happening. consequently, the potential reward for the use of a diaphragm, is Not there. the use of a balloon, frequently, results in a low-quality diaphragm. at 7:22, can you see that, due to its Location, the water is doing NOTHING. googletranslate

Good luck
That top of the can turning it over was a mind blow. I was like, "no way it's that easy"
yeah the sterling cycle is neat.
WOW...! Just WOW !
Well done...I might even have a crack at building this one myself.
Thanks for the video.
Dude! That.. was.. AWESOME!
Could you publish or provide a link for the measurements

that thing sounds great
Awesome video
bom trabalho. eu conheço, mas sempre é bom rever um pouco da ciência e bom pro jovem
Dry ice in the top could be equivalent to a turbo?
nice project .. it's super fun ..
thank you
that is fuckin awesome dude, I'm gonna make one of those this weekend
How you run it i do not understand where you add water or steam to run in cutting bottle or on another
does it actually suck, as the piston is on the cold end?
nice design and great running engine
what all materials are needed for this?

800 RPM. That’s generally what RPM a car engine idles, in gear.
You need to show " the upper part" is it filled with water?
That’s exactly what I was wondering. It seems to look like and it would create the temperature difference needed
Sounds like a diesel
I will try to make it my own
Parabéns! Eu gosto e faco alguns stirlings Também!! Êste modêlo Beta, ficou muito legal!!

I know the steel wool acts like piston rings. Lol
And the engine works on temperature difference
Один из самых простых стирлингов☝️👍💯💯💯
Plese answer
Cam we use a lower quality steel wool(steel scrub)???
the idea is that it doesn't let that much air pass through, steel wool probably wont work as well.
@@jacobgodde6576 hey can I cover one side of piston by a metal disc
I assume the vertical also attached to the crank shaft?
How does it work explain
شو هوة اللي حطيتو بالعابة المعدنية هية اسفنج
Amazing. Good. Job. My. Friend
Can I get measurements?
Does this get more powerful if you cool the cold side with cold water so the temperature difference will be bigger?
See water in top?
Can I use heavy flywheel as like bearing , will it work with heavy flywheel or not ?? Please reply back
Nice! You could add a motor to the crankshaft and start it automaticallu
Quick question: how much torque does this get?
i have no way to measure torque
Looking forward to build this. Dosen't the engine need an exhaust?

The displacer moves from TOP to BOTTOM of the can.

@@robn2497 ok i get it thanks for the explanation
What powers the engine? Why is there water on the top of the engine? Cool project. 👍
It is powered by the difference in temperature between top and bottom. In this case handle heats and water cools. Air inside expands and contracts moving the piston
@@JustinTopp I see thanks
Usually I see people just use a candle or flame.
KTProjects yea the water isn’t 100% critical but it works on a temperature difference so water keeps it cooler so it’s more efficient and will run longer as the top won’t heat up
Is it needed to hold the contraption on top of it when powering it?
Maybe not
It is top heavy, with the water being there. You would'nt want it falling over. You could add stabiliser legs.
Why wire Wool?
well done, btw, is the 3d print part made by PLA or ABS?
I would try PLA first and if it melts then use abs
request.. v8 stirling enggine
what is the power source? excuse my ignorance
Fire or heat rather
Fantastic 🌺, is it gamma type ???
Bravo
What can I use instead of steal wool
Sponge
@@BetaDoge11 high melting point sponge.

Sounds like a car engine (which make sense since it use the same principle)
Tigrou7777 not really
Very different sounds, very different principles of opperation.
How much percent beetwen size displacer and cylinder
Displacer must be one third of the lenght of cylinder
Super
Try to add some load..
Do some useful work out of it.
