Product description

Safe and reliable

  • Cast iron engine block, grid structure, high strength integral forged steel crankshaft
  • All seawater pipes are made of cast copper or stainless steel, and seawater pumps are made of pure copper, which ensure stronger corrosion resistance
  • All cooling and lubrication systems are equipped with emergency interfaces
  • Replace the filter without stopping

Strong power

  • The power coverage is wide, and the torque reserve exceeds 20%
  • Diesel engine are divided into high and low speed versions. The low speed version has higher torque value at medium and low speeds, while the high speed version has higher torque value at medium and high speeds, which makes the engines better adapt to different ship types

Economical and fuel-efficient

  • According to different operation types, high and low speed diesel engine are developed. The fuel consumption rate of low speed diesel engine is lower at medium and low speeds, while that of high speed diesel engine is lower at medium and high speeds
  • Customized design for lower fuel consumption

Comfortable and environmentally friendly

  • Vibration isolators are equipped to improve the comfort feeling of crew and passengers
  • The emission meets IMOⅡ emission requirements

Strong practicability
