德国发动机制造商曼恩能源解决方案（MAN ES）在其哥本哈根研究中心完成了首次氨发动机测试。他们在一台MAN B&W二冲程4T50ME-X型发动机上成功进行了氨燃烧试验，尤其是在先导油量和燃烧稳定性方面，得到了较好的反馈数据。基于氨燃料的固有特性，该公司采取了必要的预防措施。一旦发生氨气泄露，通过启动“水幕”，其定制的冷库可以封存氨蒸气。同时，氨发动机设计还内置了曼恩能源现有的双燃料产品组合，包括双层管道和系统通风等，以提高其安全性。曼恩能源预计将按时交付首台氨发动机，并于2026年左右在商船上运行。

German engine manufacturer MAN Energy Solutions (MAN ES) has completed the first running of a test engine on ammonia at its Research Centre Copenhagen  (RCC). The company revealed that the successful combustion was performed on a MAN B&W two-stroke 4T50ME-X type and produced positive results with particularly promising data regarding pilot-oil amount and combustion stability. During the testing, precautions taken due to the fuel’s inherent characteristics include the construction of a custom-built ‘cold hall’, which can contain ammonia vapour in the unlikely event of a leak with the activation of a water screen. Safety features from the company’s existing dual-fuel portfolio, such as double-walled piping and system ventilation, have also been built into the ammonia engine’s design. MAN ES highlighted that it broadly expects to hold its delivery timeline for the first ammonia engine, with subsequent operation onboard a commercial vessel from around 2026.
