Description
図1を参照すると、1は機関本体、2は各気筒の燃焼室、3は各燃焼室2内に夫々燃料を噴射するための電子制御式燃料噴射弁、4は吸気マニホルド、5は排気マニホルドを夫々示す。吸気マニホルド4は吸気ダクト6を介して排気ターボチャージャ7のコンプレッサ7aの出口に連結され、コンプレッサ7aの入口は吸入空気量検出器8を介してエアクリーナ9に連結される。吸気ダクト6内にはアクチュエータにより駆動されるスロットル弁10が配置され、吸気ダクト6周りには吸気ダクト6内を流れる吸入空気を冷却するための冷却装置11が配置される。図1に示される実施例では機関冷却水が冷却装置11内に導かれ、機関冷却水によって吸入空気が冷却される。
図17を参照すると、時間ta1においてリッチ制御を開始すべき信号が発せられると、吸入空気量Gaがベース吸入空気量GaBからリッチ制御のために減少された吸入空気量GaRまで少なくされる。また、EGR率REGRがベースEGR率REGRBからリッチ制御のために低下されたEGR率REGRRまで低くされる。その上で、図14に示されるように、追加の燃料WRが噴射される。その結果、燃焼室2から排出される排気ガスの空燃比(A/F)inがリーン空燃比であるベース空燃比からリッチ空燃比に切り換えられる。したがって、本発明による実施例のリッチ制御では、EGR率REGRをベースEGR率REGRBよりも低くした状態のもとで膨張行程又は排気行程に筒内に追加の燃料を噴射することにより機関燃焼室2から排出される排気ガスの空燃比(A/F)inが一時的に理論空燃比よりもリッチに保持されるということになる。
図18を参照するとまず初めにステップ100において、第1のNOx浄化方法によるNOx浄化作用と第2のNOx浄化方法によるNOx浄化作用のいずれを行うかが決定される。次いでステップ101では第1のNOx浄化方法によるNOx浄化作用を行うべきか否かが判別される。第1のNOx浄化方法によるNOx浄化作用を行うべきときにはステップ102に進んで第1のNOx浄化方法によるNOx浄化作用が行われる。即ち、炭化水素供給弁15からは図11に示される噴射量Wの炭化水素が機関の運転状態に応じて予め定められている噴射周期ΔTでもって噴射される。
図19を参照するとまず初めにステップ120では吸蔵NOx量ΣNOXが算出される。すなわち、図13に示すマップから単位時間当りの排出NOx量NOXAが算出され、排出NOx量NOXAを積算することによって吸蔵NOx量ΣNOXが算出される。次いでステップ121では吸蔵NOx量ΣNOXが許容値MAXを越えたか否かが判別される。ΣNOX≦MAXのときには次いでステップ122に進み、吸入空気量Gaがベース吸入空気量GaBになるようにスロットル開度が制御され、EGR率REGRがベースEGR率REGRBになるようにEGR制御弁17の開度が制御される。また、追加の燃料噴射が停止される。更に、オーバラップ期間OLがベースオーバラップ期間OLBになるように可変バルブタイミング機構43が制御される。
