This paper describes the experimental results on a hydrogen fueled single cylinder engine to study the characteristics of a solenoid-driven intake port injection type hydrogen injection valve. In experiments, the fuel-air equivalence ratio was varied from the lean limit at which stable operation was guaranteed to the rich limit at which flash-back occured and spark timing was also changed. As a consequence, a hydrogen intake port injection system can be easily installed on a spark ignition engine only with simple modification and the flow rate of hydrogen supplied can also be controlled conveniently. In this case, the most serious problem is flash-back and it can be suppressed by accurate control of injection timing and elimination of hot spots on the surface of the combustion chamber.
