LTD engine nr 3

This is a self-starting Ringbom engine which runs on only a small difference in temperature between the two plates. With this engine it is very important to stabilize the temperature because these engines are very sensitive to pressure differences.

When the pressure difference is too big the engine will run in an unstable condition until the pressure in the displacer cylinder has dropped and the discharger can function normally.

The technical data of this engine:
Cooling plate: diameter 220 mm; thickness 5 mm; material: aluminum.
Heat exchanger: diameter 220 mm; thickness of the flange 5 mm; discharger (centre part) 2.5 mm; material: aluminum.
Displacer cylinder: outside diameter 200 mm; inside diameter 192 mm; height of the ring 26 mm; material Plexiglas.
Displacer: diameter 191 mm; height of the discharger 12 mm; material: green insulating foam plastic board, brand STYRODUR by BASF.
Regenerator: 6 holes, diameter 30 mm, shifted 60 degrees in relation to each other in the discharger, filled with sponges of Scotch Brite.
Power piston: diameter 22 mm; piston height 22 mm; stroke adjustable between 12 and 30 mm; material: graphite.
Power cylinder: inside diameter 22 mm; outside diameter 25 mm; length 55 mm; material: brass.
Displacer piston: diameter 16 mm; height 22 mm; material: graphite.
Displacer cylinder: inside diameter 16 mm; outside diameter 18 mm; length 50 mm; material: stainless steel.
Flywheel: diameter 185 mm; thickness 4 mm; material: Plexiglas.

If it wasn't for people finding stuff like this interesting you wouldn't have the PC you use to post insulting and retarded comments which serve no purpose other than to agravate. Besides that's a rich comment comming from someone who's posted an idiotic vid on peanut butter jelly (and your spelling indicates a severe lack of education).

Dang! Quit stopping it and just let it run! :p

[frackcha]

@blizzard249 im not sure how many you would need for usable output, there are some video's of bigger sterlings giving better output... considering how thermally efficient these engines are, there must be real world applications.

[blizzard249]

@frackcha hmm, very little energy? i know its against laws but it could be possible to make that little energy into big energy using a lot of these combined.

[frackcha]

@blizzard249 a sterling engine is basically a temperature difference engine. (in layman's terms) warm air is used to drive a piston one way down a cylinder, then back.. it will run and run.. but they only give very little energy output....

@randommagnum Agreed, get your effing hand off of the wheel! >:(

[briskitup08]

Please tell me how this works, I am making a stirling engine right now, but this design looks much better.. ASAP plz tell me

[dillonkiger]

@randommagnum It show that it will restart from any position even if stopped. great way to show it is truly running on its own as well when taken off the base. Just saying

[vasoyapragnesh]

interesting ..can u tell me how it works...

[mimic58]

Interesting im currently working on machining up all the parts for my first stirling engine and ran into problems manafacturing a bush seal for the displacer rod... I like this idea :-)

[blizzard249]

how does this work??? is it soposto be an infinate motor or something??

[macrumpton]

I have never seen a diaphragm activated displacer, do you think it is possible?
