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