Very good explanation, but I have a question that no damn manual explains for some reason. When the air expands it pushes the displacer back, now does the piston cylinder actively suck in cold air or is the just the push of the displacer that does that. When does the actual gas transfer into the piston chamber? Also don't you lose compression when the displacer has all that play?

@TheMuslimKiller Remember, the piston is the driving force (the power). The displacer is DRIVEN. It only moves the air from one end to the other. Watch the video 3 times.

Excellent video!

Thanks!!

[craternack]

thanks very much tubalcain i finally got it !ive seen several explanations none as good as yours well done

i would like to build one one day ive half a chance now i understand it a bit better

.

Thank you.

Where should the displacer be when the piston is in top?

Hi Tubalcain:

I found the answer to my question about the balloon inflating and deflating, I just realized it's a closed system, so the balloon was responding to the gas expanding and contracting , rather than the movement of the flywheel causing any pressure, in other words, the flywheel just acted as a valve lever to the gas while it was expanding or contracting.

[KoalPilot]

That's the closest explanation I have seen, however, at time mark 4:30, you mention that the tube is being preheated, but somehow, your action of turning the flywheel, and making the balloon inflates and deflates, makes it appear that the heat has no bearing on the movement.

And would you please explain the 90 degrees shift, I don't see why you have no mention of it !

Great video, thanks

~Thank you for this explanation! I think I understood that!

[MrMldillman]

Thank you for this outstanding explanation...

See you again soon.

Excellent job! Thanks because this video helped me design the fundamentals of engineering thermodynamics.

Perhaps it's useful for some if you would point out that the motion of the piston leads the motion of the crankshaft when you disconnect them. That's an indication that the piston provides power.

Great explanation. You took your time for all to let it sink in. Thank you!
