Research on Pre-ignition of Hydrogen Fueled Engines Base on the Pressure Rise Rate

Mechanism of abnormal combustion, such as Pre-ignition, of hydrogen fueled engine has been described in this paper. Moreover, the relationship of pressure rise rate with spark advance and excess air ratio has also been analyzed. Finally, optimizing control model that includes pressure rise rate is established, which abnormal combustion does not happen by controlling pressure rise rate that can also be controlled by adjusting spark advance and excess air ratio.
