Description
ガソリン代替ガス燃料噴射量(n)=ガソリン噴射量(n−1)×補正係数(但し、ガソリン代替ガス燃料噴射量(n):ガス燃料を噴射する気筒の噴射量、ガソリン噴射量(n−1):前回のサイクルで検出したガソリン噴射量、補正係数:ガス燃料補正値)
の式を用いた算出手段で求められ(図4に示すような波形図)てインジェクタ2に出力される。
Claims (1)
- 既設のガソリン噴射制御装置が発信するガソリン噴射信号を基にして所定の算出方式により算出したガス燃料の噴射量をガス燃料噴射信号としてインジェクタに出力してガスエンジンにガス燃料を供給するガソリン代替ガス燃料噴射制御装置における燃料供給方法において、前記ガソリン代替ガス燃料噴射制御装置が、通常のガソリン噴射信号による燃料供給に追加して燃料を供給するための割込み噴射信号をタイマ機能を有し通常の噴射時期とはタイミングの異なる噴射信号を割込噴射信号として判定する割込み噴射信号検知手段により検知した場合に、この割込み噴射信号分として1または複数の気筒におけるインジェクタに前記ガソリン用割込み噴射信号を補正することなくそのままガス燃料用割込み噴射信号として検知とほぼ同時に出力することを特徴とするガスエンジンの燃料供給方法。
