stirling engine in progress

[deatharena89]

Hello everyone after long time posting a topic about stirling engines. Here iam making the engine in a simple way.

materials used:

cardbaord for supports.
sponge as displacer.
balloon as power piston.
steel wire as crank shaft.
CD as flywheel.

here are some pictures of my engine, i think i will finish it in a day or two. I will post the video here as soon as possible.

Interesting....are you following plans or is it your design?

It looks like a variation of the ones available online.

How much and what kind of heat source are you going to be using?
You might want to try it first and see how the sponge holds up.


Will be looking forward to your results!

it May look like but plans are different, i tested after adding the balloon displacer moves the balloon well. Iam using candle as heat source.

If the sponge is to heavy, you might also consider a piece of foam like that used for house sheathing which many LTD sterlings employ. Still can't take excessive heat but much lighter. How will you use the balloon?

Balloon is used as power piston and i think sponge can withstand low temperatures.

it goes two turns and tries to continue but stops. I think its eve to the friction at the displacer rod. Iam changing the plan WILL Update here soon.

hello everyone after a long time i made a new design but it got some leaks repaired it(pasted m-seal) at the point of leak. But the seal produces small amount of friction so i moved the displacer manually and to my surprise, the engine worked. Here is the link, soon i will post the video of the engine working by itself. This trial gave me some encouragement.
