HomeAnimation Animation The animation shows how the key parts of the engine operate. In this animation it is assumed that the hot section is at the top half of the chamber and the cold section is at the lower half (opposite from the real engine). The red region represents the foam displacer.

Here are the individual frames:

The air is in the cold lower portion, contracting, and sucking the piston up.

Much of the air is still in the cold lower portion, contracting, and sucking the piston up.

The inertia of the flywheel continues rotation in this neutral phase.

Much of the air is in the hot upper portion, expanding, and pushing the piston down.
