Claims (3)
- 機関始動時における圧縮行程燃料噴射に際しての各気筒の燃料噴射弁の開弁時間を必要燃料量と蓄圧室内の燃料圧力とに基づき決定する筒内噴射式火花点火内燃機関の制御装置において、前記開弁時間の決定時における蓄圧室内の燃料圧力に基づき燃料噴射時の蓄圧室内の燃料圧力を推定し、推定された燃料噴射時の蓄圧室内の燃料圧力を使用して前記開弁時間を決定し、決定された前記開弁時間に基づく燃料噴射弁の閉弁時期が点火時期より遅くなる時には、点火時期を遅角しても失火限界を超えない場合において点火時期を遅角して燃料噴射弁の閉弁時期を点火時期より早くし、点火時期を遅角すると失火限界を超える場合において燃料噴射弁の開弁時期を進角して燃料噴射弁の閉弁時期を点火時期より早くすることを特徴とする筒内噴射式火花点火内燃機関の制御装置。
- 前記開弁時間の決定時から燃料噴射時までに蓄圧室への燃料圧送がある時には、前回の燃料圧送による蓄圧室内の燃料圧力上昇分が前記開弁時間の決定時の燃料圧力に加算され、前記開弁時間の決定時において燃料噴射時の蓄圧室内の燃料圧力を推定することを特徴とする請求項1に記載の筒内噴射式火花点火内燃機関の制御装置。
- 前記開弁時間の決定時から燃料噴射時までに他気筒への燃料噴射がある時には、この他気筒への燃料噴射による蓄圧室内の燃料圧力低下分が前記開弁時間の決定時の燃料圧力から減算され、前記開弁時間の決定時において燃料噴射時の蓄圧室内の燃料圧力を推定することを特徴とする請求項2に記載の筒内噴射式火花点火内燃機関の制御装置。
