Mercedes-Benz MB507 engine

The Mercedes-Benz MB 507 was a four-stroke, naturally-aspirated, V-12 diesel marine engine; derived from the MB 503 gasoline engine. The MB 507 was also based on the Daimler-Benz DB 603 inverted V-12 aircraft engine, and shared an identical bore, stroke, and displacement. Unlike the gasoline-powered MB 503, the diesel-powered MB 507 did not use a supercharger.[1]
