Gamma Engine with gear-driven displacer

The Kontax Nano Gear Stirling engine is a gamma configuration engine where the 90° phase between the piston and displacer is provided by a gear-driven linkage. It has an anodised aluminium construction with delicately machined brass fittings and the solid brass flywheel rim has integral balancing, allowing the engine to run at over 2000 rpm on a tiny candle-sized flame. In operation the gears are meshed so that the displacer is advanced 90° ahead of the power piston. The gears also act as additional flywheel mass which helps minimise the vibrations inherent in a gamma engine.

How does it work?

Stirling engines work by cyclically heating and cooling the air inside the main chamber. As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small power piston which in turn drives the flywheel. The clever thing about Stirling engines is that the mechanism for cycling the heating and cooling of the air is built into the engine in the form of the displacer, which is driven by the flywheel and crank arrangement and moves the air from the warm side to the cool side and back again over and over.

Stirling engines are named after the inventor, Rev. Robert Stirling, who patented his idea in 1816.
