Re: Help Needed Building a Gamma Type Engine to Run a Model

Hey again, So my brother and I used ice as a cooling source and tested the engine again. We really tried to up the rpm. It was accidentally tested to the point of failure. This thing goes a lot faster than 300 rpm! The piston con rod tore it's mounting point off the fly wheel rod. Just 20 minutes of...

Re: Help Needed Building a Gamma Type Engine to Run a Model

http://m.youtube.com/watch?v=Sl-bG31SXYY Hey, that's a YouTube link of a video my brother got on his phone. It's not bad but I will try get a better one up and another of my heating solution. I will say it involves red hot copper, acetone vapour and atmospheric oxygen. The red hot copper acts as a c...

Re: Help Needed Building a Gamma Type Engine to Run a Model

Hi all, The engine is running! The stainless steel cylinder and displacer certainly do the job, thank you for the advice. Hopefully I can upload a video soon, probably during the week. Thank you for the help and interest, I have certainly enjoyed this project. Now I will be testing and optimizing, a...

Re: Help Needed Building a Gamma Type Engine to Run a Model

Hi all. I apologise for the late reply. I've adjusted a lot of little things on the engine, realigning the conrods and changing the points they were mounted at. A little bit of work with 2000 grit sandpaper and good cleaning out. Now a flick of the wheel with everything connected except the two cyli...

Re: Help Needed Building a Gamma Type Engine to Run a Model

Hey, I've made some progress! Thanks again for the advice. I've now corrected the ratio to 1.5:1 and shortened up the stroke to about 145 mm on the power piston. I have also lathed a new piston for the cylinder, it slides wonderfully. The displacer is now a sealed can, and 3 times it's diameter in l...

Re: Help Needed Building a Gamma Type Engine to Run a Model

Hi, thanks for your quick replies! My dimensions and plans were a combination of calculations and other engines found on the internet and were also influenced by the materials I had available to me. While the engine does look rather nice, It still needs to run! Do you think that ratio was a trial an...

Help Needed Building a Gamma Type Engine to Run a Model Car

Hi all, I have started building a gamma type engine for my final year project. The aim of the project is to run a model car with a chemical reaction. I figure a stirling engine would be a perfect way to demonstrate my proposed reaction and get people excited about these wonderful little engines as w...

Re: "Hi" We are new here!

Hi all

I'm a final year (hopefully) chemical engineering student in South Africa. I've decided to use a stirling engine in my final year project :big smile: I look forward to seeing everyone's own efforts and hopefully getting my engine to finally run after reviewing engines that really run.
