@heatherroseisrflyer Correct. Displacer con rod goes on the outside of the engine, but heat is applied to the centre of the engine and not at one end as normaly.

@myfordboy
It is a Beta engine but the displacer connecting rod doesn’t go through the engine, correct?

@waterfowlspecialist This particular one is quite low power, farctional HP. Uses are given on the ad at the begining of the video. It is possible to build more powerfull ones with modern technology.

How many hp’s can this kind of engine produce?
j4cko56 · August 18, 2011 at 2:18 am
it sounds really nice!

Thanks for interest.
The round part on the end of the cylinder at the opposite end to the flywheel contains water and this is the cold end.
The hot end is in the centre of the engine.
So working left to right we have, flywheel, power piston, Burner (hot end) displacer, cold end. The bore goes right through from one end to the other, there is no regenerator. I can email a sketch if this is not clear.

Which is the ‘cold’ end, or is there one each end? I am guessing that the burner and heater is in the middle there? And does it use a regenerator of some sort? Sorry to ask so many daft questions, but that really is a fascinating bit of kit!

No its not pressurised. Lite it up and away it goes.
brutusofbadgerfarm · August 18, 2011 at 4:49 am
This is a really splendid project, love it!
does it need an initial charge with pressurized air?
Nabo00o · August 18, 2011 at 5:17 am
I hope it could, I don’t see any problem with it, do you?
cyborgtroy · August 18, 2011 at 6:16 am
That actually wouldn’t work.

Oh, okey, so its a stirling engine.
Do you know if its possible to make it run out of cold temperature as well? Because, if you had a spessialy designed heat pump that was made to both create heat as well as cooling it can have a much higher efficiensy than the normal kind.
Now, how about making simple heat pump that supplies both cooling and heating to a specially designed stirling engine?
A normal heat pump has a COP of 3-4, this one could have 7-8…….

The engine was designed as a stirling engine from the outset.I have patent drawings for the origional and sales info.
The construction is completely different to an IC engine.
Nabo00o · August 18, 2011 at 7:56 am
I’m sorry if I wasn’t catching a obvious fact, but was that a normal combustion engine modified to reuse its rest heatproduct in the stirling process? If so, do you think it had a high level of efficiency? or should we say COP…
