I found very good material: is Rescor 740 . Is very hot resistant: 1250 celsius degrees, quite good mechanical performance, very light (0.65 kg/dm3) , is a cold-casting foam. I suppose is expensive, I think was the used for the Space Shuttle tiles. Is commercialized, perhaps is small quantities. Fer...

Excuse me, I would intervene. Bump, the displacer length/diameter ratio (said by Jian) has been defined, most likely, also to give away the hot from the cold parts, if the displacer is wide and short the hot part (including the cylinder, ...and not only the displacer) ends up to be quite cooled, and...

Explaining more clearly (and strictly excluding the Stirling which is another thing), there is "theoretically" the possibility of extracting energy (and therefore work). The calculation has to be related to the volumes displaced, that are related to absolute temperature (degrees Kelvin): F...

Jim, is your request real?
Is'nt In Norway found a normal pvc elbow, for hydraulic use???
I do not know "Quick and Easy.......", but a normal brass elbow is a lot better than pvc, (also if as bit more expensive). Less thermal expansion, and more hardy to friction.

Pete, I think honestly that this engine (gas beared) will not work. this is because the flow is unidirectional (and symmetric) in a closed cycle, (and has no mismatches that allow triggering pulse, as is the case for the Stirling). Is demonstrated that in the same symmetrical situation (with no mism...

Grazie Jim,
(Thankyou Jim)
Good work, simple and not many expensive, but of good quality.

Quart, if you indicate in your profile the land where are you from, is more easy to understand to wich technology is for you more allowable. In Australia, Africa and America is enough diffused the multicylinder derivated from the "Lister CS" diesel engine (England) , but now produced mainl...

Quarts,
why do you ask us a thing that can you find easily by a small research in net?
There are different levels of technologies.
To define "a range" is not a good idea.

It 'clear that the power output is proportional to the difference of temperature between the hot and cold site. The cold temperature can not be below ambient one. The hot site temp. depends on the heat strength of materials, materials of good quality can reach 800 to 900 ° C. It 's also clear that t...

I try to well understand, my english is poor: Yess yoy can. The arm bearing the displacer must be paid in advance of 90 degrees (approximately), respect to the movement of the piston engine. of course depending on the direction of rotation. So if you are arranged with opposite direction of rotation ...

We are interested in Stirling engine, other type of engine have to be presented in others forums.

You also need to know if one understands what it is reads. All internal combustion engines are described or describable "compared" to the Carnot cycle, this does not mean that the Carnot cycle can be accomplished. The same Carnot thought it was absolutely impossible. Not knowing this, and ...

I correct myself; ....that report the worSt results...

Welcome however, I remember a book of Andy Ross (also in net) "Macking stirling engines" that report the wordt results making use of parts of an internal combustion engine. Those who claim to work with piston rings, high masses, and even valve, may be do not have well understood how a Stir...
