Mitsubishi marine diesel engines
Specifications
Standard engine equipment


All Mitsubishi engines are designed and built to deliver performance, dependability and fuel efficiency. The combustion chamber design, the fuel injection technology, the turbocharger and the advanced cooling system have been perfectly balanced to provide highly reliable operation and optimum fuel efficiency across the entire power curve.

Maintenance is simplified as each cylinder has its own cylinder head. The engine has large inspection covers on the crankcase and oil pan*. None of the auxiliary components (fuel injection pump, governor, water pump, turbocharger) requires separate lubrication.

At Mitsubishi's ISO certified manufacturing facilities, every Mitsubishi engine is built to meet the highest quality standards, as recognized by Lloyd's Registry of Shipping and other major international marine classification societies. Mitsubishi marine engines comply with EPA and IMO emissions standards.
