Sorry so much going on I missed this,
You said the cylinder dose not know where it is. Well this is true it doesn't have a brain.
How ever there a a multitude of difference between each cly on an opposed engine, Crank angle for a start, cooling is different front to back, fuel require for the burn is different between them that's why you can use GAMI injectors. Is it injected or carby, if carby then you get a different flow between each cylinder.
Now ever wondered why P&W never made an opposed engine ? I have.
Areo engines are like no other internal combustion engine. Automotive engines don't work no matter how had they try I guess exception is a VW engine but that's not in commercial use.
Rotary's where to be the next best thing they couldn't make a gear box to take the hymonic load light enough.
