Principles of a Stirling Hot Air Engine by mrpete222

Stirling Hot Air Engine Principles Video

In this video Tubalcain goes over the principles of a Stirling hot air engine. The engine in the video is one the he built himself. It looks like he may have cast the main body of the engine and machined the rest.


Mrpete222 (Tubalcain) has many very good how-to videos on machining and model engines. I have included a link to his YouTube channel at the end of this article.

In this video he talks about Boyles Law, gas and the closed system in a Stirling hot air engine.

He also explains the Displacer and is role in the movement of the gas in the engine.

MrPete222 disassembles the engine to demonstrate the engine principles. You can hear the power piston make a pop sound when he pulls it out while showing how tightly it fits in the cylinder.

He uses the finger of a latex glove placed over the power cylinder to show how the closed system works. It expands and contracts depending where the displacer is located in the heat exchanger. This is a very good demonstration of the Stirling engine cycle. You can clearly see the expansion and contraction of the gas while inflating  and deflating the balloon.

Near the end of the video he runs the Stirling hot air engine. He also talks about efficiency and heat lost.

Quote from the Principles of a Stirling Hot Air Engine Description:

This is how a Stirling engine works.
