CW250 series marine diesel engine

Minimum fuel consumption 195g/kW.h
Overhaul period 25000h
Emissions meet IMO II/China I

Product advantages

　　Safe and reliable

High-strength body, crankshaft, connecting rod structure, high safety factor, to ensure high product reliability

　　Powerful

High-pressure fuel pump, supercharger, fuel injector and valve are optimized and matched, covering a wide range of power and large torque reserve
Low-speed and high-torque design, the diesel engine responds quickly and accelerates quickly
Optional dual-supercharger configuration, the engine has better low-speed response, and the low-speed torque reserve is further increased by 30%, with stronger power and lower fuel consumption

　　Economical and fuel-efficient

Using four-valve technology, pulse supercharging, large intake air volume, sufficient combustion, and the lowest fuel consumption rate can reach 195g/kW.h

　　Comfortable and environmentally friendly

Adopt large stiffness damping leaf spring shock absorber, low vibration and low noise
Emissions meet the requirements of IMO Tier II and China's first stage regulations

　　Practical

The supercharger can realize free end or flywheel end arrangement to meet the needs of different ship types
