三菱重工(MHI)集团旗下的三菱造船株式会社已向日本发动机株式会社(J-ENG)顺利交付用于大型低速二冲程船用发动机的氨燃料供应系统。目前，在位于日本长崎的MHI研究与创新中心，J-ENG正对其实验性大型低速二冲程船用发动机进行各种条件下的氨燃料测试。由三菱造船提供的氨燃料供应系统已经安装到该发动机上。此外，日本造船（Nihon Shipyard）、日本发动机株式会社和日本船级社（ClassNK）透露，世界上第一台四冲程氨燃料发动机已经完成了共燃比为80%的燃料氨稳定燃烧的陆基试验。随着氨成为减少温室气体排放的关键因素，曼恩能源、三菱造船等企业已率先采取行动，进一步推进航运业的能源转型。

Mitsubishi Shipbuilding, a part of Mitsubishi Heavy Industries (MHI) Group, has delivered an ammonia fuel supply system for large, low-speed two-stroke marine engines to Japan Engine Corporation (J-ENG). J-ENG is actively testing ammonia fuel under diverse conditions using an experimental large-scale, low-speed two-stroke marine engine located at the MHI Research & Innovation Center in Nagasaki District, Japan. The ammonia fuel supply system supplied by Mitsubishi Shipbuilding has been installed at the Nagasaki District facility, and supplies the ammonia fuel used to conduct the tests. In addition, Nihon Shipyard, Japan Engine Corporation and Nippon Kaiji Kyokai (ClassNK) revealed that the world’s first four-stroke ammonia-fueled engine had completed a land-based test for the stable combustion of fuel ammonia having an 80% co-firing ratio. With ammonia emerging as a key player in reducing GHG emissions, companies like MAN Energy Solutions and Mitsubishi Shipbuilding are spearheading initiatives to revolutionize the industry’s energy sources.
