WinGD Low-pressure X-DF Technology
Future environmental regulation remains the key variable for ship owners to monitor. WinGD’s X-DF engines, operating on LNG, reduce a cargo vessel’s emissions by 99% for SOx, 90% for NOx, 99% for PM and about 18% for Greenhouse gases.
The technology
Based on the lean-burn Otto-cycle combustion principle, fuel and air are premixed and burned at a relatively high air-to-fuel ratio; a concept already used widely on medium-speed engines.
The launch of low-speed dual-fuel (X-DF) engines using LNG, admitted at low pressure, and ignited by a low volume of liquid pilot fuel, was a breakthrough in the marine industry.
WinGD has applied a depth of gas engine expertise and experience to its low-speed engines – a move that extends the benefits of X-DF technology across the broader marine industry. This technology has proven effective through over 1,000,000 running hours from a variety of vessel types.
