Small Hot Bulb Engine

[Brian Hutchings]

Does anyone know if it is possible to make a miniature hot bulb engine in 1/8th or 1/4 scale?

Find Hansen has done some small ones, I have done a couple of hot tube engines at 1.5" bore.

There is a guy in Germany: G. Wilfling that has made quite a small hot tube engine.

Many thanks Dave & Jason, that another project for me to investigate; I need to live until I'm about 200 years old to build them all!

This engine is not the real hot bulb engine with fuel injection since it's a gas engine with hot tube.
