據世界天然氣網7月15日消息 總部位于芬蘭的技術集團W?rtsil?已經進行了幾次全面發動機試驗，作為其新的凈零試驗計劃的一部分。

　　據了解，這些試驗在芬蘭瓦薩W?rtsil?的發動機實驗室進行，以評估使用這些燃料運行的最佳發動機參數。

　　W?rtsil?報告稱，其中一臺測試發動機在典型的船用負荷范圍內，使用含70%氨的燃料時表現非常好，其他測試也在純氫發動機上成功完成。

　　W?rtsil?稱：“測試將在未來幾年繼續進行，目的是確定最可行的基于內燃機的發電廠和船舶應用解決方案，從而實現向綠色燃料脫碳未來的過渡。”

　　這家科技集團預計，今年將有一臺采用氨氣混合燃料的發動機，2023年將有一臺采用純氨氣燃料的發動機。

　　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.
