The hot air engine that just sits around
This Project is on hiatus

The day my version of a double acting stirling engine is done, is probably the day hell freezes over.

12 Double Acting Cylinders

both the hot side and the cold side are on one shaft and doing work at the same time in the same direction.

4 Power strokes per revolution

Since the inner cylinder of each row of cylinders is 180° apart of the 2 outer cylinders, you only get 4 independant power strokes per revolution.

0 Vibration with 3 Banks of Cylinders

Rombic Drive to minimize friction and side force on cylinder walls.

3 Banks of 4 Cylinders aranged in a "W" configuration 60° apart.
