V Shape Suction Type Double-cylinder Stirling Vacuum Engine Model High-end Creative Gifts for Collection
.100% brand new with high quality .Exquisite appearance, domineering and eye-catching, looks very mechanical and technological .A selection of high-quality materials, made of pure metal, solid and strong .The engine contains two hot cylinders with high power, and the V-shaped shape helps to achieve rapid heat dissipation and increase power .The hot cylinder and the flywheel are made of brass, which can run at high speed for a long time without wear .The product is designed with the details in mind .The whole surface is treated with smooth, bright and golden and silvery brilliance .It will not rust and fade, achieving a combination of texture and beauty .During operation, the engine model is placed in a horizontal position, and an alcohol lamp is ignited by injecting alcohol into the alcohol lamp with a syringe to ensure safety .The alcohol lamp heats the piston tube, and the dry air expands to generate power, which drives the flywheel to rotate rapidly.Use 95% alcohol (self-prepared) during operation, no water, kerosene, gasoline,lighter oil,liqueur .Education and fun, through the hands-on operation, you can observe the entire Stirling engine operation process, more intuitive understanding of the power generation principle, and deepen your interest in physics learning .The product itself has been assembled and can be directly used .At the same time, its superior quality and exquisite appearance also make it have a high collection value and can be used as a high-end gift .The product is suitable for people over 14 years old .Tips: Be careful not to be hot to the heat during the operation.
Why do I say it's a kit when it comes assembled? Because it needs a little work to get the best from it. Includes holding the cylinders in place with silicone sealer rather than the screws provided (which distort the cylinder bore.) Also you'll need to add more heatsinks if you want long stable runs and don't be afraid to tweak and tune timing and replace the cloth wiicks with fibreglass. I fully disassembled and reassembled after work with a flat-cut finishing file and taking care to eliminate friction.
To start the engine, preheat with a hair dryer; when finished, rotate the engine a good few times by hand to get any meths condensate steam out of the cylinders or they will rust and stick. Only use graphite dust for lubrication, I have an older video of tweaks and work on my channel Thomas PCGuru Engines
Alles okay super
Very cool little working model . Well made and functions very nicely. My elderly dad loves it.

I expected this purchase to be fun.... big disappointment...
According to the web page description this item... has a luminous gyroscope?... has removable & interchangeable parts... has a bulb that lights up... and comes with an extra flywheel & allen key. That's all great and sounds like a fun item, but in reality: the "gyroscope" does not light up - I suspect a dead battery, no extra flywheel was included & no allen key was included, so there is nothing to remove & interchange, the engine can barely generate 2.5V - so the 5V bulb is never going to lite up. Oddly after a few minutes of running this engine now does not even work. It does need to heat up before running but now even after 5 minutes of direct flame this engine just won't run. I can only post 1 video so I cannot show the "dead" engine. Overall I can't give this more than 1 star for the overhyped description & missing parts
The engine received was not the one shown on the website
This engine runs very well, the problem is that the engine they sent does NOT match the item in the picture. I specifically wanted a thermo stirling engine with an "extended" hot tube. What they sent was the standard "short" hot tube variety. I already have 2 engines of this style, if I wanted another I could have purchased the one from this site for $23.99 or $19.99. Instead, I paid $29.99. If Stirlingkit no longer have this item in stock, they should UPDATE their website pictures and ADVISE the customer accordingly. This is very poor business practice on the part of Stirlingkit to make an unauthorized substitution. I have been very satisfied with my other purchases from Stirlingkit up until now
Well I have built this little engine was fun to build took me from 11pm to round 7 am the next morning as I was taking my time going to put it on a stand then start it up just waiting for the stand/base for it
A nicely packed kit love how the box is wood and everything is packed in black foam trays instructions are online but the contents are in plastic box’s. Like screw’s nuts and everything else needed to build it
I sent you an email describing my research and asking to speak with your engineers about reversing the rotation. I have had no response. I am a retired electrical engineer researching chirality and Tesla's concepts on Aether and gravity.
