氨燃料二冲程船用发动机首获应用

Group 1 - WinGD has successfully installed the X52DF-A engine on a 46,000 cubic meter LPG/ammonia transport vessel for EXMAR, marking it as the first company to bring ammonia-fueled two-stroke marine engines to market [1] - The X-DF-A engine utilizes high-pressure ammonia injection technology and operates with approximately 5% low-dose pilot fuel at full load, achieving comparable load handling, dynamic response, and fuel efficiency to WinGD's diesel fuel X-series engines [1] - Key emissions metrics for the ammonia fuel engine, including nitrous oxide (N2O) and ammonia slip, have shown ideal results during testing, with emissions reduced to single-digit parts per million (PPM) without additional post-treatment devices [1] Group 2 - The 52-cylinder engine was manufactured by HD Hyundai Heavy Industries and installed on the first of four series vessels built by HD Hyundai Shipbuilding & Marine [2] - WinGD's CEO anticipates a more diversified fuel mix in the future, with liquefied natural gas (LNG) as a transitional choice, followed by methanol, and ultimately ammonia becoming mainstream [2] - WinGD has expanded its X-DF platform, initially designed for LNG, to include methanol and ammonia, and has recently introduced the X-DF-P version capable of using LPG [2]
