Stirling Engine PE2

thingiverse

A Stirling engine, functioning as a heat engine, requires approximately a 50 degree Fahrenheit (28 degree Celsius) temperature difference for operation and operates at around 300 rpm unloaded. All necessary plans and details are available to construct this engine, which includes a video demonstration on the official site: http://www.solarheatengines.com/2012/10/29/3d-printed-stirling-engine/. The zip file encompasses all 11 3D printed components for the engine, and PDF files provide assembly and part drawings. Building instructions are also available on the website. Further, an assembly bill of materials (BOM) is available along with assembly details at http://www.solarheatengines.com/2012/11/27/3d-printed-engine-bom-and-assembly-instructions/. An article on building the regenerator for the PE2 engine has also been posted, ensuring optimal performance. The same website also features alternate designs for power piston and displacer, available in piston insert 3.zip and displacer3.zip respectively. Lastly, a drill press is necessary to accurately drill out holes and lathe work on the aluminum plates and power piston.
