Yanmar Power tests high hydrogen fuel ratio 4-stroke engine for coastal vessels with diesel ignition.

Yanmar Power Technology has successfully tested a pilot-ignition hydrogen 4-stroke engine for coastal vessels, achieving a 500kW output with the highest hydrogen fuel ratio globally. This 6-cylinder engine uses diesel for ignition and is part of efforts to reduce marine emissions. Future developments include a zero-emission engine using biofuel and hydrogen, with land tests planned for 2024 and demonstrations in 2026, as part of a larger sustainability initiative.
