Abstract

　本発明の課題は、パティキュレートフィルタ６の強制再生を手動操作で行うべき運転条件が整った時に、運転者が手動操作を失念していても、自動的に強制再生が実行されるようにすることにある。圧力センサ８（堆積量推定手段）からの圧力信号８ａに基づいて制御装置９（堆積量推定手段）で推定されたパティキュレートの堆積量が自動再生範囲を超えた手動再生範囲にあると推定されている条件下で且つディーゼルエンジン１がアイドリング状態で所定時間経過しても再生ボタン１５（操作手段）が手動操作されない時に自動的に前記燃料噴射装置１０（燃料添加手段）による燃料添加を実行せしめるように前記制御装置９を構成する。
