Abstract
【解決手段】エンジン10の気筒11〜14には、吸気通路16として、主管20から分岐された枝管21〜24がそれぞれ接続される。枝管21〜24には、燃料噴射弁71〜74が組み付けられている。さらに、枝管21〜24には、EGRバルブ56の下流側でEGRパイプ52から分岐された枝管61〜64が接続されており、EGRバルブ56まで導入された排気ガスを枝管21〜24の各々に導入する。ECU1000は、排気通路18としての枝管31〜34に設けられた空燃比センサ81〜84により検出された気筒別空燃比に基づいて、気筒別空燃比の不均衡を検出する。気筒別空燃比の不均衡が生じている場合には、EGRバルブ56を閉弁させた上で、再度気筒別空燃比の不均衡を検出する。
【選択図】図1
Description
次に、図2を参照して、本実施の形態に従うECU1000により実行されるA/Fインバランスの検出動作を実現するための制御構造について説明する。
