Friction in a Small Alpha Type Engine

I am building an alpha type Stirling engine for a university project - powered by a tealight, so fairly small in size. I also have to analyse the friction in the engine, and consider how it could be optimised. One thing that I want to measure is the friction in the piston cylinder used, though I am ...

Re: Piston Cylinder Connection for Alpha Stirling

I hadn't thought about a Heylandt Crown - honestly I haven't heard of it before! How would I incorporate that into the bought in cylinders, sorry? How would the bolt fitting be attached? Just because the cylinder is made of glass I would be worried about cracking it or deforming it and blocking the ...

Re: Piston Cylinder Connection for Alpha Stirling

Thanks for your response! It is Alpha, V layout (pistons at 90 degrees to each other) with an ordinary crankshaft. Both of the hot and cold cylinders are made of glass due to the fact that we have very limited workshop time and so are buying them in, as this saves time and they have a lower coeffici...

Piston Cylinder Connection for Alpha Stirling

Hi, I am building a model Alpha Stirling engine for a university project and am having an issue with the connecting tube between the two piston cylinders. The two cylinders have a bore of 24 mm and come with a removable plastic end (which I think can act as a seal?) which in turn has a bore of 17.7m...
