Description
本発明は、こうした実情に鑑みてなされたものであり、その解決しようとする課題は、大量パージの実施に伴う排気再循環量の減少に拘らず、好適に機関制御を行うことのできる内燃機関の制御装置を提供することにある。
内燃機関の吸気通路1には、その上流から順に、吸入した空気を浄化するエアクリーナー4、吸気の温度を検出する吸気温度センサー5、吸気の流量を検出するエアフローメーター6が配設されている。また吸気通路1のエアフローメーター6の下流には、スロットルモーター7により駆動されて吸気の流量を調節するスロットルバルブ8、及び吸気中に燃料を噴射するインジェクター9が配設されている。そして吸気通路1は、吸気バルブ10を介して燃焼室2に接続されている。ここで吸気バルブ10は、開弁に応じて吸気通路1と燃焼室2とを連通し、閉弁に応じてその連通を遮断する。
(1)本実施の形態では、MBT点火時期T_AMBT及びノック限界点火時期T_AKNOKについての、排気再循環量に応じた進角補正量の算出に使用する内燃機関の体積効率(EGR補正用体積効率KLSMWP)を、パージエア量KLPGRSMに応じて補正するようにしている。そのため、大量パージの実施に伴う排気再循環量の減少に拘わらず、MBT点火時期T_AMBT及びノック限界点火時期T_AKNOKの適正な進角補正を行うことができるようになる。
・上記実施の形態では、MBT点火時期及びノック限界点火時期のEGR補正進角量AEGRMBTS,AEGRKNOKSを、パージエア量KLPGRSMにより補正された内燃機関の体積効率(EGR補正用体積効率KLSMWP)に基づいて算出するようにしていた。これらEGR補正進角量AEGRMBTS,AEGRKNOKSの算出は、体積効率の代わりにシリンダー吸入空気量を用いても行うことが可能である。その場合にも、その算出に使用するシリンダー吸入空気量をパージエア量KLPGRSMにより補正するようにすれば、大量パージの実施に伴う排気再循環量の減少に拘わらず、MBT点火時期T_AMBT及びノック限界点火時期T_AKNOKの適正な進角補正を行うことができるようになる。
