I have a gamma model diaphragm piston. the good thing is that it doesn't get hot, it's been there sometimes for a day charging the batteries and it will probably never stop running

Maybe build your fire before you light it.

Look up sunorbits sunpulse Sterling engine See what thay are using for gasket material on their diaphragm

the oil companies would completely hate this idea: run an engine on any fuel you can burn oh the horror. steam does work but you would need monotube boilers (for speed) and there is always a delay of some kind with that specific technology. also the maintenance would be kinda nasty having to clean out all that water mineral deposits. but a sterling engine you dont have that but the power is so much less vs steam with pistons or turbines but the maintenance would be so much less.

Your a Damm genius

Love the channel,bingeing it now but Jesus Christ turn down the sharpness on your camera

I like the scale of your experiments and your "DAMN THE TORPEDOES" approach.

How energy efficient would this be? How many Watts of electricity would this be able to generate?

yes, the car generator is no efficent at that. Better a 3 phase generator and a bridge rectifier (to feed a charge controller) :-)

excellent breathing some life into suburbia

The original rider used stationary leather piston seals, what seals are you using?. It also used an air-pump and relief valve to maintain two atmospheres inside the engine.

Вот это я понимаю Стирлинг ,молодец Мужик!

Fantastic . looking forward to seeing more

The easiest to understand stirling engine. A flat heat exchanger (I type)with a two-ended piston is a successful design.👍

Mi hermano Usted es un mostro, yo estoy tratando de escribirte y contactarte para saber si nos puedes ayudar desde Panamá 🇵🇦👍 Bendiciones....

AMR 500 sup[er charger on a Yan Clone diesel? would love to know more about this set up. Need a little more oomph in my diesel bike so speed of traffic on USA roads does not make driving it so risky

They are too efficient they will not let us have them !

I love the project, but I'd hate to be your neighbor :p

you should make a SMALL gamma or alpha stirling engine, while following the advice that i have offered, below. as seen on some small stirling engines, a vertically oriented loop in the duct forms a simple and effective regenerator. convective heat trap. d

At that wattage, what is its efficiency?

Love it!

Хороший аппарат. Но он не откалиброван. Иначе бы движок не трясся как лихорадочный. Да и топку лучше было бы ставить снизу, а не сбоку.

Hi Shane Congratulations, very good work. With my experience, I think of 2 modifications to try; 1) Your unidirectional valve increases the pressure in the engine but in a dissymmetric way. If you replace this valve with a very small air inlet to balance the average air pressure inside the engine with the atmospheric pressure you no longer have these disadvantages. On the contrary, you have two cycles of motor work per turn instead of one. A pression cycle and a suction cycle. The engine thus has a much smoother operation between a pressure of 0.7 to 1.3 bar for example (instead of 0 to 1.6 bar). 2) As already indicated, separate the cooling zone from the regenerative zone to increase yield. Simply isolate part of the chiller from the hot side. This has the consequence of having a regenerative effect by retaining heat in this area.

That has got to be giving out some substancial energy, did you ever measure the output on this one?

Very entertaining and fun to watch. Thanks for posting this.

You have inspired me immensely, I too am on a super limited budget and I really appreciate you posting this, would you happen to have a link to your rail bender plans, I have scoured the internet but haven't been able to find any plans. Thank you.

Nice work ! Sound is really impressive ! I would replace the alternator with a wind turbine generator given the low rpm of the stirling engine. Also would use closed circuit with a higher pressure working agent in order to maximise the power.

In order to minimise the vibration, I guess a boxer type configuration would balance the engine and make it work smoothly. Anyway is a nice machine I am going to build one myself soon!

you should try LG washing machine brushless motor, it already have neodym inside.

Very nice engine, well done.

Great to see you are still at it! Couple of thoughts... 1. The pipe between your hot end piston and cool end is a huge dead space. This messes with compression ratio hence power. This needs to be reduced to minimum (balancing mass flow vs friction). 2. Adding a true regenerator section (in its simplest form a mass of wire wool) will double output. 3. The use of a displacer adds greatly to the ability of the system to shove the hot expanded air down to the cold power piston end. That way at the end of the stroke the volume of the heated cylinder is close to zero, the air is all shoved thru the regenerator section and the total volume is just that of the interconnecting pipe + regen section + cold power cylinder at its point in the 90-degre offset stroke. Then its ditto for minimising the volume of the cold cylinder when the gas is displaced into the hot end. As your plan shows you are just kinda wobbling a long pipe full of warm air too and fro, without any decent either/or its being heated or/either cooled. So tis all mushy, IMHO. But do carry on as I am just a table top 'expert' with bits of a possible Stirling engine languishing on my bench, awaiting a coincidence of materials and skills to advance!

Bet the neighbors appreciate that infernal racket. Doesn't it have a throttle?

Always make electricity as you go accomplishing something .

Would it be possible to integrate this engine with, say, a grain thresher / winnower?

because a diaphragm acts as a spring, ANY use of a diaphragm in a heat engine is less-than ideal. the use of a spring to 'compensate for' poor linkage design is sad. when making a prime mover, it should be understood that the nominal operating speed of the engine WILL be Determined by the way it is loaded; via the crankshaft. if part of the system (say, the dum spring) seems to smooth operation, that smoothness is (probably) coming at a cost. that spring is also flailing around, ABSORBING energy. d

I really want a new series...Really!

Subscribed, can't wait to see more!

You have just taught me why torque is also called brake horsepower!

Have you thought about running this on waste motor oil as a heat source?

So steam-punk I love it!

whats power output

Try a toilet plunger

What about a big thermoacoustic engine next? See how it scales up.. 😅

Need piston with proper rings.

i wonder if you balanced the flywheel against the weights of the pistons and pushrods, it might shake a bit less. but it runs fine.good job

ever consider a Chevy one wire car alternator? Its simple as it gets used to be common in the US now can be found in speed shops mostly . w proper rpm ,14 volts is easy plus it has an internal regulator . Keeps things simple ,Best wishes sry. I'm new probably sounding like a broken record w old news

Жирный лайк разработчику, это действительно впечатляет, кто сказал,что стирлинг не эффективен? Респект вам

Какой же язык поганый. Неужели нельзя по-человечески разговаривать?

I think that chrome-nickel steel for the regenerator is not the best material. Because it has low thermal penetration. Steel wool would be much better. Carbon steel has three times greater thermal transmittance and copper has over twenty times greater thermal transmittance

I am so impressed with this design. There are other designs on UT and one in particular uses a large diameter piston with diaphragm and very slow rpm with high torque. Yours is so compact and neat. I must go back and follow the Mk4 to see how it has been developed. The guy mentioning parallelogram motion might help against fatigue damage. Take a look at steam train engines. They have linear motion conrods. So do ship steam engines like the Wavely. Hope this helps.
