The D12-800 is a further development of the successful and well-proven high pressure unit-injected and 4 valves per cylinder D12 marine engine.
Electronically governed wastegate turbo, a new-designed heat exchanger for reduced charge-air-cooling temperature in combination with a new injection system, and a new Engine Management System (EMS-2) further improve performance and driveability, meeting future stringent emission requirements. A rigid in-line six cylinder block with ladder frame and vibration dampers on the camshaft results in a smooth-running engine for high onboard comfort.
