Yanmar Power Technology has successfully completed a  test of a pilot-ignition hydrogen 4-stroke high-speed engine

Yanmar Power Technology Co., Ltd., a group company of Yanmar Holdings Co., Ltd., has successfully completed a land-based demonstration test of a pilot-ignition hydrogen 4-stroke high-speed engine for power generation in coastal vessels, achieving operation at a rated output of approximately 500kW. This trial was conducted as part of the Nippon Foundation’s zero emission ship demonstration experiment.

The tested pilot-ignition hydrogen engine operates by using a small amount of diesel oil as the ignition source (pilot fuel) to burn a premixture of hydrogen and air. With this operation, the engine achieved the world’s highest hydrogen fuel ratio and an output of approximately 500 kW, leading the industry (according to Yanmar’s research).

Going forward, Yanmar Power Technology plans to continue zero-emission trials using biofuel as the pilot fuel, while also working towards obtaining class certification for demonstration operations scheduled for 2026.
