Jens, I was searching for a good link for an opposed piston engine and couldn't find one. They do the same kind of thing. Super or turbo chargers are not meant to pressurize the charge in these large diesels. They provide primary compression that takes place of the crankcase which is running in an oil bath.
Jens, have you ever looked at the Napier Deltic engines? What a piece of engieneering.
I saw first time the opposed piston engine marine engine was in the ship "Harald Jarl" (now "Andrea" ), the engine was 5 cylinder opposed piston engine with 2 turbocharger. It was in 1986. The engine was licencebuilded (B&W) in Aker Mekanisk Verksted, Oslo in 1960. See pic. of the top of piston in engine room.
