Three Cylinder Stirling Engine

[Zerginfantry]

Am I correct in assuming this is like an IC engine, where the 'power strokes' have to occur at different times, unless a large number of cylinders are present?

[TheSdenne]

Any particular reason for the 3 or 5 "odd" number of cylinders?

[jozafax]

@TheSdenne yes, better torque distribution.

[gamercosti]

replacing the piston with a membrane = pure win.... no friction with zero precision needed. I'm gonna make one of these to take heat from my PC and replace the power LED with some cool spinning thingy (just for fun ofc)

hope there's some heat left in my power supply... all rest is gone via home made water cooling :(

[gamercosti]

u replaced the piston with a membrane... that's genius!!! (srsly) now i can make one myself using nothing but junk... as a toy for my "solar death ray" to play with

also adding something like this to the PC processor heat just for fun to replace the power LED with some spinning thingy on the case

[viseven]

I like this motor and sound!!! =D=D , like diesel hahaha

[shortattentionspan1]

...ooh man! does this machine have a sweeeeet rhythm ..... chugga ghugga

[34D2234]

sounds like the african queen

[01Slayer10]

WOOOT, Please make a How to make :D

[bocagonzalo]

the car sound, its great, well done

[wiatroda]

nice sound

[XanaduZune]

It sure makes a lot of noise for something that works on candle power. Maybe it'd be faster and more efficient if it weren't noisy. It seems like a lot of energy may be wasted on noise. But that's just nitpicking. You did a good job on making this thing.

[SpiritsoftheWolf]

well, isn't this diesel engine suppose to sounds like this?? LoL

[rdt0t]

no, because this is not a diesel engine :P,, this is a stirling engine

.. umm,, I believe it needs some more work ^^

[SpiritsoftheWolf]

@rdt0t, no duhhh i know it's a stirling engine :P it sounded like a diesel engine idling at low rpm, listen to it's rhythm -_-, if you cannot get it's rhythm, then you got a problem houston :P :P :P

[rdt0t]

lol, my bad XD. I misunderstood you

[SpiritsoftheWolf]

it's cool, some people don't get it, a lot of noise that has it's own rhythm, and when i heard this the 1st time, it sounded just like a diesel engine idling at low rpm , and i was like, neato!, anyway, glad you now understand me when i said about the diesel engine running at low RPM :)

[axyiq]

Very nice work! This is one of the videos that inspired me to build my own engine. Thanks!

[stugats77]

AMAZING!!!

[kdc43]

my 3 cyl 1.0 liter engine went out on my '94 Geo Metro.........can I put that in my car?

[mercedesfan650]

Nice job on that motor. It even sounds good! I have a question: How might you provide heat for a flat engine {I'm thinking of building a flat 8 engine like the porsche 914/8}

I think my idea might have a chance but you really seem to know what you're doing so I thought I'd ask.

[ramonnie007]

great engine, nice video, 5 stars for you.

[Stirlinggenerator]

Nice job; engine runs great !

[vengencefrom1979]

awesome

[tikifish28]

wow very nice it almost sounds like a gasoline engine

[gucketube]

Super Arbeit!

[bcdrummer]

almost sounds like a gas engine

[bronie12345]

sounds a bit like a lacer bulldog tractor :D

[dnukem88]

i like the sound of it

[popupwool]

I would say it has more power than speed because of the 3 pack and less speed because lack of precision.

[RHEAD100]

nice work;  5 stars

[solararity]

wow cool i wanna put one of those in my car

[Nicko1024]

The down side it the stirling engine it power to size ratio. They tend to need to be quite large to deliver comparable work output. And also at high temps the expensive heat exchangers needed to capture heat can become 35-50% of the engine cost. While extremely flexible steam turbines, or solar cells have better power efficiency in the larger application. However they are awesome for small scale, the coolest one I saw were computer fans driven by CPU/RAM/PSU heat.

[imikewillrockyou]

Very nice work! I think these engines could save the world, really amazing for such a simple engine. I have a coffee cup model myself, the possibilities are very intriguing.

[furzeham]

brilliant

[weldhabs]

it seems good but it need some modification and what is the purpose of it

[30GB]

wow sounds like a 2 4 stroke cylender but its 3 lol

[fmjjoker2]

That engine sounds sooo cool! kinda like chitty chitty bang bang...Can you provide instructions on how to build one like that? Parts,materials,assembly and theory. I love these engines and would like to see more and more of them using solar energy to power our world...including using them to power the apparatus necessary to run an H2O based hydrogen production plant that may provide "Green" hydrogen to replace petroleum in nearly all of our power applications ie.cars,trucks,electrical,even stove

[animagus333]

that sounds good

[enadon1]

wow

[vaxel7]

V8 haha :D Jozafax, great work, very good, continue making Stirling's :)

[matt9741399]

Excellent work. I look forward to the V8 version ;-)

[colscols]

lovely work it sounds sweet to. thanks for that.

[BoldUniverse]

Awesome machine man, thanx for that. When you build bigger, better Stirling's, more power to ya.

[wolih]

Oh its nice, but noisy lol....!

Did you design it yourself from the home-made instructions?

[jozafax]

:))) Actually, i'm designing the instructions while home-making a five cylinder version of this engine by myself, yes.

[Ungleubiger]

super!

[rmedinaesquivel]

I really enjoy your beatiful and creative work on this engine.

[Garry1906]

How much power can this deliver in watts

[jozafax]

Never measured but a rough guess would be around 3 Watts. And even such a small number seems to me as an overestimate: 3 Watts means lifting an approx. 300 gram weight 1 meter in 1 second.

I've built this engine just for my own amusement and am really happy that it even overcomes its own friction. The sound is really industrial but the engine does much more bark than bite.

Cheers from Slovenia.

[crob227]

saying that if your producing sound,thats energy-or energy wasted?

[jozafax]

Yes, but not wasted since i enjoy the sound :)

[crob227]

i got a coil im using in a hho prodject it makes audible sound with the frequncy its at.

so i know what you mean its the sound of great work. check out my page. stumble onto video's is the coil im talking about

[rwhendrix]

Amazing engine!!! Could you imagine a straight 6cylinder putting along?

[jozafax]

Thanks! Nooo, not in a M'years :)) ,but i'm currently building a 5cyl inline (see link in the video description).

P.S.: i took a peek at your videos, your homebuilt tank is simply amazing, respect!

[slh950]

wow ... people like you are going to change electricity generation

[jordan0867]

how much horse power

[jozafax]

Never measured but a rough guess would be around 3 Watts.

[360russ]

het thats very cool nice work.

[Sterling0011]

it sounds like suction cups on a window

[CyberdyneTechnician]

It Sounds Really Cool.

[hwymadness850]

how can I learn more about how this works?

[jozafax]

Just google for "stirling engine".

[CITRATODESODIO]

the sound seems at Grandma's Laundry

[socrunningman]

Hey, I was thinking about constructing a 4 cylinder "V" Engine based on your design. I was wondering if you could post the materials used and the construction process on your site. I built a single cylinder model out of aluminum cans and it ran into some problems, especially with regards to the crankshaft.

Thanks

[jozafax]

I started the 5-cyl-inline build because a couple of people asked for a plan, so i will document it as i go (i'm a bit tight on my regular job; civil engineering branche and no minus temperatures in sight (not even on the Celsius scale...), but the documentation will be avaliable in December 2007).

I actually planned a v-twin for the next project and, if the twin would prove itself, a v10.

If you have a chance to mail me the pictures of your engine, we could perhaps figure the problem out.

[socrunningman]

I am working out the mechanics of the "V" type now, I think that I have the basic geometry right in theoretical terms, and by geometry I mean that of the Crank Shaft. The biggest thing about a "V" Type engine is that it would have to be very tight fitting, with a lot of moving parts really close to one another. I would like to make it is the Gamma/Beta...

[socrunningman]

configuration (that is, what yours is) but an alteration of side mounted driving pistons would actually make the entire design a lot easier, I think this can be done by connecting a longer pipe diagonally to 90degrees so that it functions as part of the supporting structure as well.

Pictures of my RC cola can engine or that of the V which I am planning on building?

[jozafax]

I can't quite picture what you ment. It is all about timing; you need a 90 deg. phase shift between the displacer and the power piston of each displacer/piston pack ("cylinder"), and your multi-cylinder configuration should provide an even torque distribution through each crankshaft revolution.

I ment the pictures of the engine you have trouble with.

[spoiledworm]

thats pretty cool sounding

[Erikdb]

Would really love to share building ideas... do you have a website with instructions?

[jozafax]

I set a simple page up today (see the video description).

[Erikdb]

Thanks! Those detailed pictures are helpful. I'll wait also for your 5 cilinder construction photos. You did great work. What pages did you use as reference material/inspiration?

Again: great work and I appreciate it A LOT not trying to keep it to yourself (like way too many people do)!

[jozafax]

Thank you very much for the kind words. See the links link at the bottom of my page. SFA Stirling engine project got me started

[tsport100]

Put an actual LOAD on it!

[jozafax]

I'm working on a RC trike, powered by this engine.

[SpiritsoftheWolf]

wow sounded like a diesel engine idling real low... gool vid 5/5

[antidartan]

did you take pictures during construction?

[jozafax]

No, i didn't. I could take some detail pictures and send it to you via email, if you wish.

[antidartan]

very cool, started without a push. Can you post specifics like displacer material and dimentions, ect.ect.

[jozafax]

Thank you. I nicked the flywheel to start it, it is just out of the cameras view.

[jozafax]

The displacer is made from an aluminium mushroom pate can (outer diameter: 70,3 mm, producer: Schneekoppe). This information is useless unless you have a pressure vessel (in my case a 0.25 l steel paint can, inner diameter: 72,7 mm) with the right diameter  (on this scale, the gap between the displacer and the pressure vessel should be 1-3 mm). The pressure vessel top originally also contained the mushroom pate but from another producer: Tartex.

[noaa20]

Muito legal...

[temperimagination]

Ful dober mašin maš ti to! :O ;)

[jiggi4]

cool! add rap to it so you now have a hip hop machine

[gilbondfac]

Great !!very good

[tylerkb12]

I LOVE IT!!! Sweet sound, and it looks like it's big enough to do some real work. Make it run something like a generator or a boat or an R/C car.

[samoht1977]

It would be nice to see a boat running with some sort of that engine...

[userlaalaa]

amazing timing! sounds like an old tractor :) i like it!

[Skoda130]

My compliments. And it sounds nice too!

[67561a]

holy cow!!! 5 Stars for you!
