X82DF-2.0

The newest two-stroke dual-fuel engine, offering enhanced propulsion options within the VLCC, VLOC and Panamax container vessel segments.

WinGD’s low-pressure dual-fuel technology is a sustainable propulsion solution that runs safely, reliably and efficiently on gas as a cleaner option over conventional heavy fuel oil or diesel oil. Further optimising the standard X-DF portfolio, WinGD now offers X-DF2.0 technology providing reductions to both fuel consumption and methane slip in gas mode. iCER – the Intelligent Control by Exhaust Recycling system, is the first application of X-DF2.0.

Benefits include:

  • Up to 3% energy consumption reduction in gas mode
  • Up to 5g/kWh fuel consumption reduction in diesel mode
  • Up to 50% reduction of methane slip.

The X82DF-2.0 fulfils Tier III emission requirements without any external exhaust gas after treatment system when operating in gas mode.  

The X82DF-2.0 is available as 6 to 9 cylinders configuration, covering a power range from 14’940 to 38’880 kW at 58 to 84rpm.
