W12 Stirling Engine
the goal is to have a simple to produce engine.
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
Rombic Drive to minimize friction and side force on cylinder walls.
"W" configuration for 0 vibration.
3
Banks of Cylinders
Aranged in a "W" shape 60° apart.
