This Stirling engine is a heat engine that operates by cyclic compression and expansion of air at different temperature levels. The burner heats the glass tube causing the displacer piston to be pushed out, allowing the air to flow into the adjacent cylinder and be cooled by the alloy fins which in turn draws the metal piston upward in it's cylinder to complete the cycle.
The simple stirling engine is a great looking working model to display on a shelf with its Nickel plated finish and CNC machined brass and alloy components, it's a great way to amaze visitors or teach others about internal/external combustion engines.
You will need only Methanol or Methylated spirit to power the engine.
Just received it today 08/01/15,no problems noted great for my kid,for school demonstration Thank you HKAt first a was a bit worried as the box looked like it had been used in a rugby match, but fortunately most of the parts were still okay. I only needed to place 1 part back and it all worked.
I filled the holder with methylated spirit and after some time to warm up let her spin. It worked great first time. I get about 15 minutes of runtime out of one filling. I works as advertised, just a fun little machine, I like it a lot.First he had not enough power, i made the rod length longer 18.5 mm from the piston to the rod end. now here is working fine.
