Abstract
電子制御装置6は、PM及びNOxを浄化するフィルタ35の硫黄堆積量を機関運転状態に基づいて推定する。推定値Sxが判定値Smax以上となることを条件に、フィルタ35温度を温度αにまで上昇させるとともに排気空燃比を低下させてフィルタ35から硫黄を放出させる第1の再生処理を実行する。第2の再生処理が実行された後における第1の再生処理の実行回数Nが判定回数A以上であるときに、フィルタ35温度を温度β(>α)にまで上昇させるとともに排気空燃比を低下させてフィルタ35から硫黄を完全に放出させる第2の再生処理を第1の再生処理と各別に実行する。第2の再生処理が完了したときに推定値Sxをリセットする。それにより、実際の硫黄堆積量とその推定値との間の乖離が大きくなった場合であっても、これを修正することができ、エミッションの悪化を抑制することができる。
