Re: First Stirling Engine Help

Oh that's right, trying to reduce all around friction is a good idea.

I'll likely have more questions along the way, but if not I will at least post the final product for others to see.

Thanks for the continued help,

Re: First Stirling Engine Help

Is a hollowed out displacer always necessary? I've seen both solid and hollow across the internet.

Is it possibly a modification you would do later if the engine is running poorly and the flywheel cannot handle the displacer weight?

Re: First Stirling Engine Help

Thanks for the replies! Along with those recommendations, is there any material for any part that is BAD to use? Also (if it works) i've attached images of my cad design, and im wondering if there are any obvious issues. Base Plate is around 8x16 inches, cylinder OD (hot end) around 1.9 inches for r...

Re: First Stirling Engine Help

Hello, I've gone through the design process and have finalized my design with CAD software but I am still considering a few things and need some suggestions. I am on a budget of $300 and I am wondering what materials to make the following parts out of: 1) Cylinder (with fins) 2) Displacer Piston and...

Re: First Stirling Engine Help

Thanks Ian I appreciate the help. I have another idea though and am wondering what you think of it. I'm trying to eliminate the need of a crankshaft by centering the flywheel with the cylinder and having 1 pin on either side (one for each piston con rod) therefore both will be offset. Is this still ...

First Stirling Engine Help

Hi I've recently starting planning designs for a Beta Stirling Engine that I am building for my college course. I'd appreciate any help or opinions with the following 2 things: 1. Piston and cylinder design (Ratios etc.) (What I'm mostly worried about is if the stroke length needs to be higher due t...
