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
