Abstract
Description
図1に示すように、本実施形態の燃料噴射制御装置が適用されるエンジン10は、直列に配列された4つの気筒#1〜#4を備える直列4気筒のエンジンとして構成されている。エンジン10の吸気通路11には、同吸気通路11を流れる吸気の流量(吸入空気量)を検出するエアフローメータ12と、吸入空気量GAを調整するためのスロットルバルブ13とが設けられている。吸気通路11におけるスロットルバルブ13よりも下流側の部分には、吸気を気筒別に分流するための分枝管である吸気マニホールド14が設けられている。そして、エンジン10には、吸気マニホールド14で気筒別に分流された吸気中に燃料を噴射する燃料噴射弁15が気筒毎に設けられている。さらに、各気筒#1〜#4には、吸気通路11を通じて導入された吸気と燃料噴射弁15が噴射した燃料との混合気を火花放電により点火する点火プラグ16がそれぞれ設けられている。
吸気分配補正値A[i]は、吸気マニホールド14での吸気分配のばらつきにより生じる気筒間の空燃比のずれを補償するための燃料噴射量の気筒別補正値である。エンジン10の運転領域毎の気筒間の吸気分配のばらつきは、エンジン10の設計段階で計測されており、吸気分配のばらつきによる空燃比のずれの補償に必要な各気筒#1〜#4の気筒別補正値がその計測結果から予め求められている。電子制御ユニット21のメモリ23には、エンジン10の運転領域毎の各気筒#1〜#4の吸気分配補正値A[i]の値がマップとして記憶されており、電子制御ユニット21はそのマップを参照して各気筒#1〜#4の吸気分配補正値A[i]の算出を行っている。
燃料噴射弁15の噴射特性には個体差があり、全気筒に同量の燃料噴射を指令しても、実際に噴射される燃料の量には、ばらつきがある。一方、空燃比センサ19に対する排気のガス当たりの強さには気筒毎に違いがあり、ガス当たりの強い気筒ほどその燃焼の結果が空燃比フィードバック補正値FAFの値に反映されやすい。例えば、ガス当たりの強い気筒に、指令した量よりも多い量の燃料を噴射する燃料噴射弁15が設置されている場合、空燃比センサ19の排気空燃比の検出結果は、各気筒#1〜#4の空燃比の平均値よりもリッチ側の値を示す。こうした空燃比センサ19の検出結果にそのまま従って、空燃比フィードバックを行えば、エンジン10の空燃比が定常的にリーン側にずれてしまう。このように、空燃比センサ19に対する各気筒の排気のガス当たり強さの違いにより、目標空燃比に対する空燃比の定常的なずれが生じてしまう。
過熱による触媒装置20の溶損は、空燃比を理論空燃比よりもリッチとしたリッチ燃焼を行って多くの未燃燃料を含んだ排気を排気通路17に排出し、その未燃燃料の気化熱で排気の温度を下げることで防止することができる。ただし、エンジン10の気筒#1〜#4のすべてでリッチ燃焼を行うと、触媒装置20での排気の浄化効率が低下してしまう。これに対して本実施形態では、触媒装置20の温度が既定値を超えたときに実施する過熱防止制御において、一部の気筒だけでリッチ燃焼を行うことで、排気の浄化効率の低下を抑えつつ、触媒装置20の昇温抑制を図っている。
本実施形態の燃料噴射制御装置では、エンジン10の冷間始動の直後に、触媒装置20の暖機促進のためのディザ制御を行っている。ディザ制御では、気筒#1〜#4のうちの一部でリッチ燃焼を行い、残りの気筒でリーン燃焼を行うようにしている。そして、リーン燃焼を行った気筒の余剰酸素を多く含んだ排気により、触媒装置20内を酸素過多の状態とした上で、リッチ燃焼を行った未燃燃料を多く含んだ排気を送り込んで燃焼させることで、触媒装置20の昇温を促進している。
電子制御ユニット21は、上記のような燃料噴射量の制御に加え、各気筒#1〜#4の点火プラグ16の点火時期の制御も行っている。点火時期制御に際して電子制御ユニット21はまず、燃料噴射量の気筒別補正が行われていないとした場合の各気筒共通の点火時期の目標値である最終点火時期IGを算出する。ちなみに最終点火時期IGの値は、各気筒#1〜#4の圧縮上死点からのクランク角の進角量を表している。
本実施形態のエンジン制御装置では、気筒内で燃焼する混合気の空燃比に気筒間の格差が生じるように燃料噴射量の気筒別補正を行っているため、理論空燃比と異なる空燃比で燃焼が行われることがある。
・ガス当たり補正値B[i]やディザ制御補正値D[i]と同様に、気筒#1〜#4の値の合計がゼロとなるように過熱防止補正値C[i]の値を設定するようにしてもよい。こうした場合、過熱防止補正の実行中も、排気浄化性能の低下を抑えることが可能となる。
