4F30.10 - Stirling Engine

Code Number:
Demo Title:
Stirling Engine
Thermal/Carnot Cycles
Area of Study:
Heat and Fluids
Stirling Engine, Fuel Pellets, Bunsen Burner, Grill Lighter, Graphite Lubricant -- Only if needed!!, and 3 - in - 1 Household Oil.

Video Credit:  Jonathan M. Sullivan-Wood.

The fuel pellets seem to run this the best although the Bunsen burner will work.  Lubrication is critical as any friction will keep the engine from starting or running.  A drop of oil on the two flywheel bearings and the main piston shaft will usually be required.  DO NOT OVER LUBRICATE THE PISTON SHAFT!! DO NOT USE OIL ON THE EXTERNAL SILVER PISTON - A very small amount of graphite is to be used ONLY WHEN NEEDED!!  When the heated chamber reaches a sufficient temperature a small turn of the flywheel in the counterclockwise direction will start the engine.

The multi-gang Stirling engine is very cool.  Fill all 4 burner reservoirs with alcohol to the marked level.  Allow a few seconds for the alcohol to wet the wicks.  Light all 4 reservoirs, and in about 20 seconds you will be able to start the unit by turning the flywheel in the marked direction.  This is a very smooth running unit.
