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
