Abstract
【解決手段】推定される触媒周りのPM堆積量が許容値以上になることに基づき、触媒周りに堆積したPMを燃焼させて除去するPM再生制御が実行される。このPM再生制御が中断された場合、後に同制御を実行可能な状態になると、そのときのPM堆積量が許容値未満であったとしてもPM再生制御が再開される。このようにPM再生制御を再開させることで、同制御を完了するまで続けて触媒周りに堆積したPMを燃焼しきることができる。そして、PMが燃焼しきってPM再生制御が完了したときには、推定されるPM堆積量が「0」にセットされ、そのPM堆積量と実際の堆積量との誤差が解消される。
【選択図】 図1
Description
上記目的を達成するため、請求項1記載の発明では、排気系の触媒周りに捕集された微粒子の堆積量を推定し、その推定される微粒子の堆積量が許容値以上であることに基づき、前記触媒に未燃燃料成分を供給して同触媒を昇温させるとともに前記捕集された微粒子を燃焼させるPM再生制御を行い、同制御の完了時に前記推定される微粒子の堆積量を「0」にセットする内燃機関の排気浄化装置において、前記PM再生制御が中断されたときには、後に同制御を実行可能な状態になった際、前記触媒周りの微粒子の堆積量が許容値未満であっても前記PM再生制御を再開するものとした。
図1は、本実施形態の排気浄化装置が適用される内燃機関10の構成を示している。この内燃機関10は、コモンレール方式の燃料噴射装置、及びターボチャージャ11を備えるディーゼル機関となっており、大きくは吸気通路12、燃焼室13、及び排気通路14を備えて構成されている。
なお排気通路14の上記PMフィルタ26の上流側及び下流側には、PMフィルタ26に流入する排気の温度である入ガス温度を検出する入ガス温度センサ28、及びPMフィルタ26通過後の排気の温度である出ガス温度を検出する出ガス温度センサ29がそれぞれ配設されている。また排気通路14には、上記PMフィルタ26の排気上流側とその排気下流側との差圧を検出する差圧センサ30が配設されている。更に排気通路14の上記NOx触媒コンバータ25の排気上流側、及び上記PMフィルタ26と上記酸化触媒コンバータ27との間には、排気中の酸素濃度を検出する2つの酸素センサ31、32がそれぞれ配設されている。
・PM再生の要求時である。ここでのPM再生要求は、機関運転状態から推定されるPMフィルタ26等でのPM堆積量が許容値以上になることに基づき、上記PMフィルタ26の詰りの発生が確認されたときになされる。
・上記入ガス温度センサ28の検出値(入ガス温度thci)がPM再生制御実施の下限温度A(例えば150℃)以上である。また機関運転状態の履歴から推定されるNOx触媒の触媒床温が、PM再生制御実施の下限温度B以上である。これら下限温度A、Bには、未燃燃料成分の供給に伴って触媒床温を上昇させられるだけの酸化反応を生じさせることのできる排気温度及び触媒床温の下限値がそれぞれ設定されている。
・入ガス温度センサ28の検出値が、PM再生制御に伴う発熱による触媒の過昇温を回避し得る温度範囲の上限値C未満である。
・出ガス温度センサ29の検出値が、同じくPM再生制御に伴う発熱による触媒の過昇温を回避し得る温度範囲の上限値D未満である。
・排気に対する燃料添加の実施が許可されている。すなわち、排気燃料添加の実施を許容できる機関運転状態にある。この内燃機関10では、エンジンストール中でなく、気筒判別が終了しており、且つアクセル開度の制限がなされていないのであれば、排気燃料添加が許可されるようになっている。
図2は、NOx触媒コンバータ25やPMフィルタ26での触媒昇温の上昇に伴い、触媒の表面に付着した未燃燃料(HC)及びPMの燃焼率がどのように推移するかを示すグラフである。同図から分かるように、触媒に付着した未燃燃料は触媒床温が比較的低い温度(300℃前後)で燃焼し、触媒に付着したPMは触媒床温を上述したように600〜700℃といった温度まで昇温することで燃焼するようになる。従って、PM再生制御において、触媒床温をいきなり700℃近い温度まで上昇させると、触媒に付着した未燃燃料やPMが大量に燃焼し、その際の熱を触媒が受けて触媒床温の過上昇に繋がるおそれがある。
(1)PM再生制御の中断後に同制御を実行可能な状態になると、そのときのPM堆積量が許容値未満であったとしてもPM再生制御が再開されるため、同制御を完了するまで続けて触媒周りに堆積したPMを燃焼しきることができる。そして、PMが燃焼しきってPM再生制御が完了したときには、推定されるPM堆積量が「0」にセットされ、そのPM堆積量と実際の堆積量との誤差が解消される。従って、PM再生制御が完了しきらないまま、同制御の実行・中断が繰り返されるのを抑制し、その繰り返しの間にPM堆積量と実際の堆積量との間の誤差が大きくなるのを抑制することができる。
・PM再生制御の実行時間を必ずしもPM堆積量に応じて可変とする必要はなく、その実行時間を触媒周りに堆積したPMをPM再生制御によって燃焼しきるのに十分な時間に固定してもよい。
