Description
特許文献1の制御装置では、発熱量の異なる複数の気体燃料を任意の供給割合で混合して機関に供給する際に、ノックが発生した場合に燃料の供給割合または点火時期のいずれか一方を変更することによりノックを抑制している。
ところが、複数燃料の供給割合を機関運転条件などに応じて変更する場合、必ずしも全部の燃料が一様に消費されるわけではなく、各燃料の消費にアンバランスが生じる場合がある。
図1は、本発明の制御装置を自動車用内燃機関に適用した場合の実施形態の概略構成を説明する図である。
従って、この場合も燃料残量のアンバランスが大きくなると、消費量の少ない方の燃料タンクが満杯になってしまいそれ以上燃料を貯留できなくなって、燃料の分離を停止しなければならなくなる場合も生じる。
次に、本実施形態のノック抑制操作について説明する。
点火時期遅角量Ardは、増大補正量Rhgと同様にノック強度を用いた一次元数値マップとしてECU30のROMに予め格納されている。
本実施形態では、KCSは運転時に機関の点火時期をノックが発生しようとする限界付近まで進角させてできるだけ実際の点火時期を最適点火時期に近づける制御を行っており、ノックセンサ37で検出したノック強度が所定の下限値(ノックとして運転者が体感するノック強度より遙かに低い値が下限値として設定されている)より低くなっている場合には、点火時期の進角要求を出力する。
そこで、この場合にはステップ219からステップ223に進み高オクタン価ガソリン燃料の供給割合の低減補正量Rlwがノック強度に基づいて算出される。
一方、ステップ217で点火時期進角要求がなかった場合には、すなわち現在点火時期を変更する必要はないため、ステップ211から223を実行することなくステップ225に進む。この場合にはRhg、Rlw、Ard、Aadの値はいずれもゼロにリセット(ステップ207)されたままでステップ225が実行される。
図2の操作では、ステップ215と223とでノック強度に応じて燃料供給割合の変更量(図2の例では高オクタン価ガソリンの供給割合の増減量RhgとRlw)を算出し、算出した増減量だけ燃料供給割合を変更している。
これにより、燃料残量アンバランスを改善するとともに、より確実にノックを抑制することが可能となる。
ステップ21501はステップ215で供給割合の増大補正量Rhgが決定された後に実行され、増量不足分Rhimの値が、Rhim=RR+Rhg−Rhmax、として算出される。ここで、Rhmaxは(本実施形態では高オクタン価ガソリンの)供給割合の上限値である。供給割合上限値Rhmaxは、それ以上高オクタン価ガソリンの供給割合を増大することができない最大値であり、通常は100パーセントに設定されるが他の制約条件に応じて100パーセントより小さい値に設定してもよい。
従って、この場合はステップ21505から21507を実行することなく、ステップ225(図2)に進み、燃料供給割合RRfinを算出する。
これにより、ステップ225で算出される増大後の供給割合RRfinはRhmaxに等しくなる。
この場合には、供給割合の低減(ステップ225)と点火時期の進角(ステップ227)とが同時に行われる。
上述した図2、図3の操作ではKCSがノック発生の可能性を検出した場合に点火時期の遅角または高オクタン価燃料の供給割合の増量が行われる。
図4の操作では、まずステップ401で機関の要求負荷の増大速度が検出される。本実施形態では、要求負荷増大速度はアクセル開度(アクセルペダル踏み込み量)の変化速度として検出され、ステップ401では機関のアクセルペダル近傍に配置されたアクセル開度センサにより検出したアクセル開度の変化率dAccが算出される。変化率dAccは、例えば前回本操作実行時から今回本操作実行時までのアクセル開度の増大量として算出される。
また、ステップ409とステップ411では、ステップ407で補正した供給割合が高オクタン価ガソリンの供給割合が上限Rhmaxを越えないように制限される。
