Abstract

For the realization of Carbon Neutrality, hydrogen is considered to contribute to decarbonize various industriesand being focused. In transportation sector, hydrogen engines are studied in addition to FCEVs. Since hydrogenhas the property of being ignited more easily than gasoline, abnormal ignition is likely to occur. In this paper, themechanism of abnormal ignition peculiar to hydrogen is studied.
