Description
更に、本発明では、排気フィルタに捕集された排気微粒子を酸化処理するフィルタ再生制御と、NOxトラップ触媒の硫黄被毒を解除する触媒再生制御とを交互に連続して実行し、前記排気微粒子を酸化処理する再生制御毎に、目標フィルタ温度,目標排気空燃比,目標再生制御時間のうちの少なくとも1つを変化させると共に、前記再生制御を、少なくとも上死点近傍で1回行われる予備燃焼と、該予備燃焼が全て終了した後に開始され主トルクを発生させる主燃焼とからなる燃焼モードによって行う構成とした。
また、排気フィルタに捕集された排気微粒子を酸化処理する再生制御における目標フィルタ温度,目標排気空燃比,目標再生制御時間のうちの少なくとも1つを変化させることで、多量の排気微粒子が急激に燃焼することによる排気フィルタの溶損を回避しつつ、再生を効率良く行えると共に、上死点近傍の予備燃焼によって筒内温度を高めることで、主燃焼のリタードを進めることができ、目標の排気温度への制御性を向上させることができる。
