Stirling Engine Generator Mk4 (Rocket Stove!) Part 6

Building of an easy, cheap and reliable, DIY stirling engine full size model! It will be fired by wood and could be a great stirlingkit if it works!


This is a fun engineering project that I will use to power a generator to provide energy. It will use an efficient rocket stove that burns really hot using wood that will hopefully drive it at great speed! This technology can use any fuel type with the correct burner so is dual fuel as well. I would like to provide plans / stirling engine kit for DIY builds and possibly build machines too.
This is all pivots on being able to produce an easy, cheap and reliable stirling engine! Watch this space…..

So, This week I've been making some support rings for the piston diaphragms and fitting a bigger flywheel to help extract energy out the engine and provide a more even stroke.

The compression ratio is now 1: 1.6 which I think isn't to bad considering the piston / cylinders are simply rubber diaphragms.

The test run went a bit better this time and the engine showed a bit more willing! The seal assemblies are a bit noisy and the pistons are imbalanced but it does run fairly well.

Well, I think it might be time to a dynameter run to see what power it's giving out. It's going to take me a few weeks to get all the parts together to do this so watch this space

All the best


Thanks for watching
