An Overview of Pre-ignition of Hydrogen Engine

Hydrogen engine has attracted much attention due to its high combustion efficiency, low hydrogen concentration requirement, low environmental pollution and fuel regeneration. But the key issue pre-ignition has hindered the development of hydrogen engines. In order to have a more in-depth understanding of pre-ignition, this paper reviews the mechanism of pre-ignition, the relationship between the nature of hydrogen and pre-ignition , the key factors affecting pre-ignition and the research status of pre-ignition, analyzes the development trend of hydrogen engine and provides a new perspective for the study of inhibiting pre-ignition.
