Abstract
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.
Keywords: Hydrogen engine, pre-ignition, mechanism, new perspective
