A proven and reliable engine platform for fuel flexible vessels
WinGD is a pioneer in modern dual-fuel technology for two-stroke marine engines, with LNG fueled engines in operation since 2016. The well-established X-DF engines series offers a range of benefits over other dual-fuel engine concepts. Already matured into its second generation, X-DF2.0 offers a viable and proven step today towards meeting the long-term climate ambitions of ship owners, regulators and society.
As shipping looks to new carbon-neutral and zero-carbon fuels, WinGD is expanding its X-DF portfolio to include ammonia and methanol engines, blending the proven dual-fuel expertise with the Diesel Cycle performance and reliability of WinGD’s X-Engines.
X-DF for LNG
Using WinGD’s dual-fuel X-DF engines gives operators flexibility in reducing emissions. Fossil LNG offers an immediate 15-20% reduction in greenhouse gas emissions. By blending or replacing fossil LNG with carbon-neutral synthetic or bio-LNG, operators can reduce their emissions further without modification.
The low-cost, highly efficient and reliable fuel injection concept used by WinGD’s dual-fuel LNG engines offers several advantages over other dual-fuel engine concepts:
- Simple installation, low-cost auxiliary systems and low power consumption contribute to lower investment and life cycle costs
- Extremely small pilot fuel quantity, below 1% of total heat release
- Engines can be operated on gas down to very low loads
- Low NOx emissions, close to zero SOx emissions and IMO Tier III compliance without exhaust-gas after-treatment
- Particulate matter emissions significantly reduced.
X-DF for ammonia and methanol
X-DF-M methanol-fueled engines and X-DF-A ammonia-fueled engines will be available for newbuild vessels from 2025. The new engines will run on the high-pressure Diesel cycle, with WinGD’s X92-B engine providing a well-proven and highly efficient base design on which to build new fuel capability.
Following their launch, retrofit packages will be available for all X and X-DF engines currently in service.
