X40DF-1.0

For small LNG carriers up to 15,000 m3

WinGD, the marine industry’s leading low speed gas engine developer, extends its offering in the low-speed dual-fuel engine series. Based on the X40-B design, the X40DF-1.0 engine is now included in the portfolio.This Otto cycle engine uses natural gas as fuel, making it Tier III compliant without the need for an expensive exhaust gas cleaning process, such as a scrubber or SCR systems.

The low-emission operation provides clear environmental benefits, such as:

  • Close to zero SOx emissions
  • Very Low particle emission
  • IMO Tier III compliance of NOx emissions, without exhaust-gas after treatment

The X40DF-1.0 is available in 5-cylinder up to 8-cylinder configuration, covering a power range from 2,775 to 7,480 kW at 104 to 146rpm.
