Power range：530kW~735kW
Applications：inland cargo ships and coastal fishing boats; 3,000-7,000t transport ships; 32-45m trawlers, etc.
The application of the four-valve technology ensures substantially increased flow area of intake and exhaust, more uniform atomization, more complete combustion, small exhaust smoke, low fuel consumption, flat curve, and larger economic working area.
High strength alloy cast iron engine block and integral forged steel crankshaft ensure the safe operation of the engine, reliability and longer service life.
Modular design, wet cylinder liner, one cylinder head for one cylinder, and side window of engine block enable easy installation and maintenance.
The application of efficient turbocharged & intercooled technology enables higher power per liter and torque, sufficient margin of power, high working performance, and various operating conditions.
