Description
また、排気タービンの膨張比を適正な比率で維持するために最低限必要な排気フィルタの圧力差と大気圧との関係は、大気圧が低いときほど上記最低限必要な排気フィルタの圧力差が大きくなるといった関係になる。しかも、この関係は、大気圧が低いときほど、同大気圧の変化に伴う上記最低限必要な圧力差の変化量が大きくなるといった関係になる。上記内燃機関によれば、そうした関係に合わせて排気フィルタの圧力差の前記下限値を設定することができるため、大気圧に応じて排気タービンの膨張比を適正な比率で維持することができる。
以下、過給機付き内燃機関の第1実施形態について説明する。
図1に示すように、内燃機関11は、吸気通路12、燃焼室13、及び排気通路14を備えている。吸気通路12の最上流部には、同吸気通路12に吸入された空気を浄化するエアクリーナ15が設けられている。また吸気通路12には、エアクリーナ15から吸気下流側に向けて順に、過給機16のコンプレッサ17、インタークーラ18、及び吸気絞り弁19が配設されている。吸気通路12は、吸気絞り弁19の吸気下流側に設けられた吸気マニホールド21において分岐されており、この分岐部分を通じて、内燃機関11の気筒毎の燃焼室13に接続されている。
図2に示すように、内燃機関11では、排気フィルタ84のPM堆積量が多いときほど排気フィルタ84の排気上流側と排気下流側との圧力差ΔPが大きくなる。また、図3に示すように、上記圧力差ΔPが大きいときほど、タービン下流圧PB(詳しくは、排気タービン27と排気フィルタ84との間の部分の排気圧力)が高くなる。これら関係からも明らかなように、内燃機関11では、排気フィルタ84におけるPMの堆積量が多くなると、排気フィルタ84の流路抵抗が大きくなるために、タービン下流圧PBが高くなるとともに排気フィルタ84の圧力差ΔPが大きくなって、排気タービン27の膨張比が小さくなる。
図6は上記停止処理の実行手順を示しており、同図のフローチャートに示される一連の処理は、所定周期毎の割り込み処理として、電子制御装置90により実行される。
(1)大気圧センサ93によって検出される大気圧PAが低いときほど前記圧力差ΔPの下限値を大きい値にした。そのため、大気圧PAが低くタービン下流圧PBが低くなり易いときに、排気フィルタ84のPM堆積量を多くしてその分だけタービン下流圧PBを高くすることができ、同タービン下流圧PBを高い圧力のままで維持することができるようになる。これにより、排気タービン27の膨張比が過度に大きくなることを抑えて、同排気タービン27の耐久性能の低下を抑えることができる。しかも、機関出力の大きな低下を招くことなく排気タービン27の膨張比が過度に大きくなることを抑えることができる。
以下、過給機付き内燃機関の第2実施形態について、第1実施形態との相違点を中心に説明する。
図7に示すように、この処理では先ず、機関回転速度NE、燃料噴射量、及び大気圧PAに基づいて前記下限値が算出されるとともに(ステップS21)、排気フィルタ84の圧力差ΔPが下限値以下であるか否かが判断される(ステップS22)。そして、圧力差ΔPが下限値よりも大きいときには(ステップS22:NO)、排気タービン27の膨張比が過度に大きくなる可能性が低いとして、PM発生フラグがオフ操作される(ステップS23)。PM発生フラグは、オン操作されているときにはPM発生モードでの機関運転が実行される一方、オフ操作されているときにはPM発生モードでの機関運転が禁止されるようになるフラグである。そのため、ステップS23の処理では、PM発生モードでの機関運転が禁止されて、通常モードでの機関運転が実行される。
本実施形態では、排気フィルタ84の圧力差ΔPが下限値以下になると、排気タービン27の膨張比が過度に大きくなるのを抑えるために、PM発生モードでの機関運転が実行される。これにより、通常モードでの機関運転時と比べて内燃機関11の排気に含まれるPMの量が多くなるため、排気フィルタ84に堆積するPMの量が増加してタービン下流圧PBが高くなり、排気タービン27の膨張比が小さい比率で保たれるようになる。
(他の実施形態)
なお、上記各実施形態は、以下のように変更して実施してもよい。
