None the less although not finish, this Instructables will be enough for you to build a low cost running Stirling engine design manual pdf engine and more. Honestly while building this project I want to find the best materials available but then my budget restrict me from doing it. Here is my guide to make it run in few attempts.
If you find it useful please hit favorite and share. The Stirling engine that I made is beta type where the displacer and piston is in the same cylinder. There are many types of Stirling engine but all works in the same process. It relies on expansion and contraction of gas inside a confined space. When the air inside the cylinder is heated it will expand and when cooled it contract. All 4 image are borrowed from there respected sites. I would like also to mention approtechie for his Stirling engine which inspires me to create my own.
Some of measurement are almost identical to his engine including the use of stainless bottle as cylinder. In order for you to build a running engine might as well read this pdf from Andy Ross a prominent Stirling Engine experimenter. If your engine doesn’t work for the first time don’t worry because I made 5 different engine using different materials from trash to barely running to wow! Prepare the materials and tools necessary for the project. This part was second most laborious to my part because I started my project without a guide or manual.
It was like an building a puzzle and its pieces are not included in the set. The engine cylinder will house the displacer and the piston. If you have a better way of cutting it do it. I only done it because its the only tools I have.
