Study of factors influencing thermally induced backfiring in hydrogen fueled engines, and methods for backfire control

摘要: The problems of intake manifold backfire and decreased engine power output have been obstacles to automotive hydrogen use. Thermal causes backfiring are investigated using a CFR an electronically controlled, timed fuel injection system. Correlation timing reported. It is concluded that both maintenance low average in-cylinder temperatures the use some means for timed, delayed delivery essential achieving backfire-free operation under all conditions. 13 refs.
