Abstract
Description
本実施形態の内燃機関システム1の概要について説明する。内燃機関システム1は、自動車等の車両に用いられる。
次に、制御部19が行う空燃比制御について説明する。制御部19は、空燃比制御において、空燃比センサ17で検出された空燃比(検出空燃比)と目標空燃比とのずれ量である空燃比ずれ量を修正するために、A/Fフィードバック学習(空燃比学習)を実行する。そして、制御部19は、このA/Fフィードバック学習を行うことにより前記の空燃比ずれ量を修正するためのA/Fフィードバック学習値を算出し、算出したA/Fフィードバック学習値に基づき、燃料噴射弁によるエンジン11への燃料の噴射量(エンジン11への燃料の供給量)を制御する。
以上のように本実施形態では、制御部19は、A/Fフィードバック学習の実行中にパージ制御を実行する。そして、制御部19は、A/Fフィードバック学習の実行後に、パージ濃度の検出を行い、A/Fフィードバック学習値からパージ濃度の寄与分の値をオフセットしたA/Fフィードバック学習補正値を算出する。
