  • The performance of the solenoid actuated hydrogen injector and the capacitive peak-hold type driving circuit was predicted through the modeling of the injector and the driving circuit the modeling was composed of the driving circuit, the solenoid, the moving parts of the injector, and the hydrogen injection system. The performance of the injector through the modeling was compared with the results of the solenoid and injector rig tests, and those were consistent with each other. Through the prediction of the injector performance, the effects of the components such as electrical resistor, capacitor, and injector spring are easily known to the injector performance required.

  • The solenoid actuated hydrogen injector and the capacitive peak-hold type driving circuit were designed and made, and the hydrogen supply system for in-cylinder injection was constructed with these. The performance of the injector was investigated through measuring the pintle lift profiles and the injection quantities, and the performance of the hydrogen supply system was confirmed through the experiments at the single cylinder engine. The injection quantity increased linearly as the duration of driving signal increased. At the single cylinder engine, the hydrogen injector was operated stably. The hydrogen flow rate of the injector with the peak-hold type driving circuit could be controlled precisely at high engine speed or low load condition only with the variation of signal duration.
