Description
調整することにより、車両走行時のように内燃機関の運転状態が変化し易い時であってもパティキュレートフィルタが過昇温しない範囲で高圧PM再生処理を行えるようにした。
ためのPM再生処理を行うPM再生手段と、PM再生処理実行時に排気絞り弁の開度を減少させてパティキュレートフィルタ内の圧力を高める高圧化手段と、高圧化手段によりフィルタ内の圧力が高められている時の機関運転状態とパティキュレートフィルタの状態との少なくとも一方が予め定められた高圧PM再生処理禁止領域に属するか否かを判別する判別手段と、判別手段により機関運転状態とパティキュレートフィルタの状態との少なくとも一方が高圧PM再生処理禁止領域に属すると判別された時は高圧化手段によるパティキュレートフィルタ内圧力の高圧化を解除し、判別手段により機関運転状態とパティキュレートフィルタの状態との少なくとも一方が高圧PM再生処理禁止領域に属していないと判別された時はパティキュレートフィルタの温度が上限値に達する可能性が高いほどパティキュレートフィルタ内圧力が低くなるように高圧化手段を制御しつつPM再生処理を継続させる制御手段と、を備えるようにした。
し難くなる。
は通常のPM再生処理を継続してもよい。
ィルタ温度が上昇し易くなる。この傾向は、PM残量が多くなるほど顕著となる。
(<A)の時の境界線Lnに比べ、流入排気量が多く且つPM残量が少ない時であっても高圧PM再生処理が禁止されるように定められている。
おいてフューエルカット条件が成立しているか否かを判別する。フューエルカット条件としては、アクセル開度(アクセルポジションセンサ17の出力信号)が“0”であり且つ機関回転数が所定回転数以上である条件を例示することができる。
開度が更に減少させられると、フィルタ内圧力Pfが過剰に高くなると同時に流入排気量Fexが過剰に少なくなる可能性がある。フィルタ内圧力Pfが過剰に高くなると同時に流入排気量Fexが過剰に少なくなると、PM酸化速度の上昇と排気がパティキュレートフィルタ11から持ち去る熱量の減少との相乗効果によってパティキュレートフィルタ11が過昇温する可能性が高くなる。
理)の実行中であるか否かを判別する。前記S402において否定判定された場合(高圧PM再生処理と通常のPM再生処理の何れも実行されていない場合)は、ECU16は、S406へ進み、排気絞り弁12の開度を減少させることにより排気ブレーキを発生させる。
