- エンジンの排気エネルギでタービンが駆動され、吸気を圧縮するコンプレッサを回転させるターボ過給機であって、該ターボ過給機がタービンのジオメトリを変え得るジオメトリ可変機構を備える可変容量ターボ過給機と、
前記エンジンの排気通路に介装され排気を浄化するNOxトラップ触媒もしくはDPFの少なくともいずれか一方と、前記排気通路と前記エンジンの吸気通路とを連通するEGR通路と、
前記EGR通路の流路断面を調節するEGR弁と、
前記吸気通路に設けた吸気絞り弁と、
車両の減速を検知する手段と、
前記車両の減速を検知し、かつ所定の条件を満足する期間中は燃料噴射をカットして燃料カット制御を行う燃料カット制御手段と、を備え、
前記燃料カット制御実行中であって、前記吸気絞り弁を閉弁するときは、前記ターボ過給機の容量が大きくなる方向にジオメトリを変更し、かつ、EGRガスの逆流によるサージ騒音を防止するために、燃料カット開始時に前記EGR弁を閉弁し、
前記タービン上流の排圧が車両の減速開始にともなって低下してコンプレッサ下流の吸気圧より低くなってから再び吸気圧より高くなるまでの差圧逆転期間が終了するタイミングで、前記EGR弁を開弁し、前記ターボ過給機の容量が小さくなる方向にジオメトリを変更し、
前記吸気絞り弁は前記差圧逆転期間の終了後も前記燃料カット制御終了時までは閉弁したままにすることを特徴とするエンジンの制御装置。 - 前記燃料カット制御手段は、
前記燃料カット制御の開始に伴い噴射量を減量し、遅れ時間をもって燃料カットに移行する請求項1に記載のエンジンの制御装置。
