This Stirling engine is a heat engine that operates by cyclic compression and expansion of air at different temperature levels.
The lamp heats the glass tube causing the piston to be pushed out, allowing the air to flow into the cylinder and be cooled by the alloy fins which in turn pushes the metal piston to complete the cycle. We have had this engine up to 400RPM!
The simple stirling engine is a fantastic item to display on a shelf with it's highly polished components it's a great way to amaze visitors or teach others about internal/external combustion engines.
You will need only Methanol (95% of greater) to power the engine.
I received it four months after I placed the order. The transverse or horizontal metal (aluminum) arm that is fixed to the main vertical pillar and that supports both the flywheel and the engine block was bent so that the cooling cylinder was raised in relation to the working piston. That way the conrod was pushed and angled towards the rim at the top of the cooling cylinder impeeding rotation and movement of the engine. Dealing with aluminum I removed the arm and put it in a vice to carefully bend it back. Wether it works or not I have yet to find out.
Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.
The Stirling engine is noted for its high efficiency compared to steam engines, quiet operation, and the ease with which it can use almost any heat source.
I've found 11 groups of these scum. One was so involved he was acting as a female and was a guy. He was making about $15.00 a day. But people are learning how to spot them and reporting them as soon as they get spotted. Now all we need is people to actually ask questions and not keep making stupid comments like Nickeystar and Ortiz above. or the one below. "When will it be back in stock?" How the heck do we know and HK don't read these questions.
I brought one just after asking this question, almost 4 mounths still waiting, if it was shiped on the slow boat from china when I purchased it. It would have done 7 trips to Australia buy now. Maby it was not backorded until there was enough people on the backorder list.
only comes in one size. "wicked". i just got mine, i needed to adjust the crank rod slightly,(very easy to do. bought some fondu making fluid and the thing runs like a sewing machine. i love it. i wish i could do more with it. my boss wants one now. lol.
I just got the first HK Catalog I've ever heard of in the US, and I am fired up! Internet is nice, but nothing like having a color catalog in hand! As a result I saw this Stirling Engine, and I had no idea that they were here! Been wanting one for years now, but never saw a reasonable price on one before. But of course, they are on back order .... Wonder what other jewels I haven't found yet? I'm surprised that I found things I haven't seen here before.
Yep, and next delivery will probably come in maybe half a year or more. They should have ordered a larger shipment. They obviously have problems with their supplier or something because they cant be this disrespectful towards their customers just for fun.
When will this arrive in stock again? Is it possible to dissassemble. Does it operate with atmospheric preassure or is it possible to increase the preassure without too much air leaking out? Will the glass and engine in general endure the high temperatures caused by different fuels' flame. What fuels are appropriate from this standpoint?
this is a hot air engine, you can not increase the preassure, glass is good enough for alcoolic spirit, 90 or 95, it runs for about 20mn, then you have to turn it by hand for 30sec. not to damage the plastic O ring. I don't know if it will be in stock, the brand name is UMS technology.
I JUST ORDERED ONE (LUCKY I GUESS) FROM WHAT I HEAR YOU CAN ALSO USE MEDICAL GRADE RUBBING ALCOHAL BUT THE FUEL REC. WOULD BE THE BEST BECAUSE IT BURNS CLEANER, DEPENDS ON HOW HIGH THE WICK IS, WOULD DETERMIN HOW FAST IT RUNS.
A nice model, and great value. It can run quite fast or nice and slow by adjusting the wick. A few thoughts: - Adding a drop of 3-in-1 oil on the bore of the displacer piston (*not* the power piston on the top) helped to keep it running smoothly. - The link on the displacer scrapes against the crank. Bending it gently fixes this. - There was excess glue on the glass bulb, this can be scraped off. - The packing tape pulled off some varnish.

1 thumbs up!
works just better than expected, I have to fix some problems, don't know if it was during shipping but the glass bulb was not horizontal. then a little oil on the wheel (not on the engine), the copper ring on the top of the engine needs to be on the other side on mine, fixed it too. I am fascinate by the way it runs, Thanks HK !

This is not my first engine of this type. It runs just fine with a few minor adjustments. Just things that happened during shipment.
once everything was in alignment again, runs like the proverbial
sewing machine. I am just using rubbing alcohol. Just follow the instructions, and a little common sense, and all should be fine. I would like to see a little better packing.
Works very well, and very fast. I have it running with medical alcohol.

An excellent engine to show off how it works. It started right out of the box with no mods or tweaks. Having read earlier posts, I added a small drop of rc car ball bearing oil to all the moving parts and it ran like a charm! I used medical alcohol also, and it was fast! Then, Mrs Wife demanded it on her library shelf as a nice ornament! Why not?!!!!
The packaging was very good, even though an "extra length carton box", was added to the order, which I'm not sure was needed or eventually used! The engine box was quite small, anyway.
