Description
また、本発明に係る燃料切替制御装置において、前記制御手段は、前記第1燃料の圧力が下限閾値を下回った場合には、前記第1燃料の遮断弁を閉弁すると共に前記第1燃料の噴射弁の作動を停止させ、他の燃料への切替えを行うことを特徴とする。
一方、本発明に係る燃料切替制御方法は、第1燃料の使用時に、前記第1燃料の圧力が上限閾値を越えた場合には、前記第1燃料の遮断弁を閉弁して前記第1燃料の供給を停止させる一方、前記第1燃料の噴射弁の作動を継続させ、前記第1燃料の圧力が低下判断閾値を下回った場合には、前記第1燃料の噴射弁の作動を停止させ、他の燃料への切替えを行うことを特徴とする。
以下では、上記のような気体燃料の使用時における燃料切替制御について、図4のフローチャートを参照しながら詳細に説明する。
CPU66は、気体燃料の使用時において、まずステップS1の処理として、リリーフモードフラグが「1」にセットされているか否かを判定し、「No」の場合にはステップS2の処理に移行する一方、「Yes」の場合にはステップS6の処理に移行する。ここで、リリーフモードフラグとは、後述のように、気体燃料の圧力(燃圧値)が上限閾値を越えた場合に、「1」にセットされるフラグである。
CPU66は、上記ステップS1において「No」の場合、つまりリリーフモードフラグが「1」ではない場合、ステップS2の処理として、A/D変換器61から得られる燃圧値が上限閾値を越えたか否かを判定し、「No」の場合にはステップS3の処理に移行する一方、「Yes」の場合にはステップS4の処理に移行する。ここで、上限閾値は、気体燃料の高圧異常が発生したことを検知するための閾値であり、リリーフバルブ45の作動設定圧力より低い値に設定されている(図5参照)。
CPU66は、上記ステップS2において「No」の場合、つまりA/D変換器61から得られる燃圧値が上限閾値を越えていない場合、ステップS3の処理として、その燃圧値が下限閾値を下回ったか否かを判定し、「No」の場合にはステップS5の処理に移行する一方、「Yes」の場合にはステップS7の処理に移行する。ここで、下限閾値は、気体燃料の低圧異常が発生したことを検知するための閾値である(図5参照)。
CPU66は、上記ステップS2において「Yes」の場合、つまりA/D変換器61から得られる燃圧値が上限閾値を越えた場合、ステップS4の処理として、リリーフモードフラグに「1」をセットした後、ステップS5の処理に移行する。
CPU66は、上記ステップS3において「No」の場合、または上記ステップS4の処理終了後、ステップS5の処理として、気体燃料によるエンジン1の運転制御を行う(その後、ステップS1の処理へ戻る)。具体的には、CPU66は、遮断弁駆動回路63に遮断弁制御信号を出力することで遮断弁41を開弁し(気体燃料タンク40の燃料出口を開放し)、気体燃料噴射弁23への気体燃料の供給を開始すると共に、ピストン11が燃料噴射時期に対応する位置に到達した時点で、燃料噴射制御信号を燃料噴射弁駆動回路62に出力することにより、気体燃料噴射弁23による気体燃料の噴射を実施する。
CPU66は、上記ステップS1において「Yes」の場合、つまりリリーフモードフラグが「1」にセットされている場合、ステップS6の処理として、A/D変換器61から得られる燃圧値が低下判断閾値より高いか否かを判定し、「No」の場合にはステップS7の処理に移行する一方、「Yes」の場合にはステップS8の処理に移行する。ここで、低下判断閾値は、燃圧値が高圧異常状態から安全な状態へ戻ったことを検知するための閾値であり、上限閾値と下限閾値との間の値に設定されている(図5参照)。
CPU66は、上記ステップS3において「Yes」の場合、または上記ステップS6において「No」の場合、ステップS7の処理として、液体燃料によるエンジン1の運転制御に切替える。具体的には、CPU66は、気体燃料噴射弁23の作動を停止すると共に、通信回路60を介して液体燃料による運転指示を1st−ECU5に送信する。これにより、1st−ECU5のCPU59は、燃料ポンプ31の駆動によって液体燃料噴射弁22への液体燃料の供給を開始すると共に、ピストン11が燃料噴射時期に対応する位置に到達した時点で、液体燃料噴射弁22による液体燃料の噴射を実施する。
CPU66は、上記ステップS6において「Yes」の場合、または上記ステップS7の処理終了後、ステップS8の処理として、遮断弁駆動回路63に遮断弁制御信号を出力することで遮断弁41を閉弁し(気体燃料タンク40の燃料出口を遮断し)、気体燃料噴射弁23への気体燃料の供給を停止する(その後、ステップS1の処理へ戻る)。
(1)上記実施形態では、ガソリン等の液体燃料と圧縮天然ガス(CNG)等の気体燃料とを選択的に切替えて単一エンジンに供給するバイフューエルエンジンシステムを例示して説明したが、複数種類の燃料を選択的に切替えて単一エンジンに供給するシステムであれば本発明を適用することが可能である。例えば、CNGと、ガソリンと、軽油とを切替可能なシステムであれば、CNGの圧力異常時に、ガソリン或いは軽油による運転制御に切替えれば良い。
