Description
内燃機関の排気によりタービンが回転駆動されるターボチャージャと、
EGR装置と、
を備え、
過給時にEGRを行う、又は過給時のEGR量を過給されていないときと比較して増加させることを特徴とする。
回るようになる。これに対し、吸気弁の開弁時期の進角量を制限すれば発生トルクの低下を抑制することができ、さらにこの範囲内で内部EGRガス量を最多とすることにより過給圧上昇の応答性の向上を図ることができる。なお、「所定範囲」とは、次回以降のサイクルにおいて排気のエネルギの増加による過給圧の上昇が機関発生トルクの減少による過給圧の低下を上回ることができる範囲とすることができる。すなわち、この範囲内であれば、吸気弁の開弁時期を進角させて現サイクルの機関発生トルクが低下しても、次回以降の機関発生トルクの低下を抑制することができる。さらに、排気弁の開弁時期の遅角を組み合わせることにより、機関発生トルクを増大させることができる。
吸気弁および/または排気弁の開閉時期を変更する可変動弁機構と、
排気の温度を検出する排気温度検出手段と、
を備え、
排気の温度が所定温度以上となる運転領域では、吸気弁の開弁時期の進角制御を禁止し、且つ排気弁の開弁時期を所定量遅角させることを特徴としてもよい。
これにより、機関発生トルクをより増加させることができる。なお、「吸・排気側VVT制御領域」であって吸気管3の圧力が排気管4の圧力以上のときの制御が行われている期間を図3では(3)の記号で示している。
給が必要な場合に所定時間毎に繰り返し実行される。
