The “Other” 261 Cylinder

That last description is correct for the strato type engine. It basically sticks a lump of clean air in front of the next charge of fuel air in the transfers so when the burnt exhaust needs to be pushed out of the exhaust port it is with clean air rather than fuel/air some of which would have escaped out of the exhaust so this makes the strato system a cleaner engine.
