Product description

Safe and reliable

  • The frame type main bearing structure; high rigidity; high safety performance index
  • The internal and external double-circulation water cooling method is adopted, and the water jacket exhaust pipe can be selected, so as to prolong the service life of the diesel engine, and the overhaul period is 20000h
  • Replace the filter without stopping

Strong power

  • Large power reserve; torque reserve reaches 20%-35%
  • The configuration of high-pressure oil pump, turbocharger, and fuel injector is optimized; the acceleration of ships is quick; the navigation speed is high

Economical and fuel-efficient

  • The intake and fuel supply system is optimized, which broadens the economic operation range of the diesel engine
  • The fuel consumption is low under normal working conditions, and the minimum fuel consumption is 195g/kW•h
  • Customized design for lower fuel consumption

Comfortable and environmentally friendly

  • Strengthen the design of key components, so that the products are featured by small vibration and low noise
  • IMOⅡ ship emission standards are met

Strong practicability

  • LCD Internet instrument can be selected to monitor the speed, water temperature, oil temperature and pressure of diesel engine in real time, so as to achieve timely automatic alarm and stop when the parameters exceed the limit values
  • Stormy wave mode is added to ensure that the ship engine will not stop at critical moments such as stormy waves
  • There is a large amount of the products in the market, and the reserve of spare parts is sufficient, which make maintenance convenient
