据世界天然气网7月15日消息 总部位于芬兰的技术集团W?rtsil?已经进行了几次全面发动机试验，作为其新的净零试验计划的一部分。

　　据了解，这些试验在芬兰瓦萨W?rtsil?的发动机实验室进行，以评估使用这些燃料运行的最佳发动机参数。

　　W?rtsil?报告称，其中一台测试发动机在典型的船用负荷范围内，使用含70%氨的燃料时表现非常好，其他测试也在纯氢发动机上成功完成。

　　W?rtsil?称：“测试将在未来几年继续进行，目的是确定最可行的基于内燃机的发电厂和船舶应用解决方案，从而实现向绿色燃料脱碳未来的过渡。”

　　这家科技集团预计，今年将有一台采用氨气混合燃料的发动机，2023年将有一台采用纯氨气燃料的发动机。

　　W?rtsil? tests pure hydrogen/ammonia engines

　　Finland-based technology group W?rtsil? has performed several full-scale engine tests running on ammonia and hydrogen as part of its new net-zero test program.

　　As informed, the tests were carried out in W?rtsil?’s engine laboratory in Vaasa, Finland, to assess the optimum engine parameters for running on these fuels.

　　The company reported “encouraging results”, with one test engine performing very well when running on fuel with 70% ammonia content at a typical marine load range. The other tests were also completed successfully on an engine in pure hydrogen operation, W?rtsil? claims.

　　“Testing will continue throughout the coming years with the aim of defining the most feasible internal combustion engine-based solutions for power plant and marine applications, thereby enabling the transition to a decarbonised future with green fuels,” according to W?rtsil?.

　　The technology group expects to have an engine running on an ammonia blend already this year and an engine concept with pure ammonia fuel in 2023.
