Description
この空燃比制御装置は、空燃比センサによって検出される空燃比である検出空燃比が目標空燃比よりも大きい場合、検出空燃比が目標空燃比に向かって小さくなるように燃焼室に形成される混合気の空燃比を制御し、検出空燃比が目標空燃比よりも小さい場合、検出空燃比が目標空燃比に向かって大きくなるように混合気の空燃比を制御するようになっている。
更に、本発明の空燃比制御装置は、各燃焼室における空燃比間に偏差が発生しているとき或いは各燃焼室における空燃比間の偏差が予め定められた偏差よりも大きい場合、内燃機関から排出される排気ガスの排気エミッションの特性が所期の特性になるように目標空燃比を補正する目標空燃比補正を実行する。
そして、本発明の空燃比制御装置は、第1モードによる内燃機関の運転の制御が実行中である場合の前記空燃比補正量を、第2モードによる内燃機関の運転の制御が実行中である場合の前記空燃比補正量よりも小さい値に設定するようになっている。
