Hello, currently i'm doing a research of the stirling engine and i'm looking for a cross section of the 2 piston and 4 cylinder model of it and i was wondering if maybe anyone would be able to provide me with it. I am also looking for any informations about rinia type engine as well as it's cross section. Thank you very much for your help.

It must be able to run on a 100o F temperature differential, and it must be able to fit in a 3 x 4 inch oval opening.

Thanks.
