Product description

  Safe and reliable

  • High strength engine block, crankshaft and connecting rod, the large-flow lubrication system with filtering before cooling and the high-efficiency cooling system, and the design of less tubes and one block and one head ensure that the overhaul period of diesel engine is not less than 20000h; Strong power 

  Strong power

  • Through the reasonable matching of electronical-controlled high-pressure common rail system, turbocharger, injector, air duct and combustion chamber, the torque reserve of the whole engine reaches more than 20%, and the torque of normal speed is greater than the calibration point torque, which make the engines meet the actual use needs of users

  Economical and fuel-efficient

  • The electronical-controlled unit accurately controls the fuel injection timing and quantity
  • Large air intake, sufficient combustion, and wide economic operation range

  Comfortable and environmentally friendly

  • The high-pressure common rail system with ultra-high injection pressure and mushroom-shape valve type deflation valve turbocharger are adopted, giving consideration to both economy and emission. The economic operation range is wide (700~1200r/min), the minimum fuel consumption rate can reach 190g/kW•h, and the emission can meet IMOⅡ requirements

  Strong practicability

  • LCD Internet instrument can be selected to monitor the speed, water temperature, oil temperature, oil pressure and other parameters of a diesel engine in real time. When the parameters of the diesel engine exceed the limit, it can automatically alarm and stop the engine, and the addition of stormy wave mode ensures that the ship engine will not stop at critical moments such as stormy wave
