2.670 Stirling Engine Animation
At right is an animation of the 2.670 Stirling engine.
Air in the engine is cyclically heated (by an alcohol
burner) and expands to push the power piston (shown in
blue) to the right. As the power piston moves to the
right, the yellow linkage forces the loose-fitting,
red "piston" (on the left half of the machine)
to displace air to the cooler
side of the engine. The air on the cool side loses
heat to the outside world and contracts, pulling the
blue piston to the left. The air is again displaced,
sending it back to the hotter region of the engine, and
the cycle repeats.
The Stirling engine cycle can also be used "in reverse",
to convert rotating motion into a temperature differential
(and thus provide refrigeration).
