X52DF

For gas and bulk carriers, handymax tankers, feeder container vessels, RoRos and general cargo ships

WinGD low-pressure dual-fuel technology has been developed to respond to the market requirements of providing a propulsion solution capable to run efficiently, effectively and safely on gas, on top of conventional heavy fuel oil or diesel oil. The technology is based on the low pressure gas system concept. This system has a competitive initial investment and fulfils Tier III emission requirements without any external exhaust gas after treatment system. In brief, the technology allows a merchant two-stroke engine to simply, safely and reliably run on gas.

The X52DF is available in 5-cylinder up to 8-cylinder configuration, covering a power range from 4,850 to 11,920 kW at 82 to 105rpm.
