Stirling Engine 2

Less basic cooling method, with closer fitting displacer packed with steel wool - stack of stainless steel mesh would probably be better. Some attempt at retaining heat from blowtorch.

Hello,

whats happening if you delay the work piston with 45-90 degree?

[james9149]

It runs best at about 85-90 deg. phase offset (as here), but a small angle change makes little difference. Change from +90 deg. to -90 deg. and it rotates the other way.

[trossachs2003]

Seems nice and smooth. Main question is why is your power cylinder so far from the displacer. You talk about a closer tolerance of your displacer and hint at a heat exchanger but the big drawback is the distance between your displacer and the piston which is "dead" air and just absorbs your power. Why didn't you put the piston on the same side as the displacer (offset from the displacer rod)?

[james9149]

Yes, cylinders need to be closer - if connecting tube is too thin it impedes airflow, while wide tube increases dead volume. Ideally flywheel should be outside and power cylinder between the side plates with very short connecting duct to displacer. Haven't made the appropriate crank yet.

You need to reveal the heat source, looks like you are using compressed air, and also show this device under some kind of useful work load. I'm tired of watching too many of these alternative energy device videos shown here not performing any work load, which makes them very doubtful they will perform under any type of load at all! To coin a phrase "You can fool Some of the people Some of the time, but you can't fool All of the people All of the time!"

[james9149]

Heat source is a gas blowtorch. Read comment below on physical size of engine needed to generate 'useful' power output at atmospheric pressure. To get anywhere near the theoretical high efficiency of the Stirling cycle, and be of compact size, it needs to run at very high internal pressure, and use hydrogen or helium as the working gas. See for example, "Stirling Engine Design Manual', W. R. Martini.

real nice thumbs up

[liveuk]

Your not supposed to laugh lol nice one get the cat in the video too just for fun

is it you who have made it ?

you can make one for me? I pay it !!!

springs you need springs

How come no one ever puts magnets on the fly wheels of these neat machines?

you coould presurize the whole unit and really get the power up.

great!

Are you running cam? :) Because it really does sound like an old v8 car idling.
