Abstract
【解決手段】給油箇所300が異なることによる、所定制御が実行された際のエンジントルクTeの特性の差異が所定判定値以上である場合には、エンジントルクTeの特性の差異は燃料FUELの性状が異なることに起因するものであると特定されるので、燃料FUELの性状が異なることによるドライバビリティの悪化を速やかに検出することができる。例えば、給油箇所300が異なることによるエンジン12の始動制御が実行された際の初爆発生時間TM1の差異が所定判定値以上である場合には、初爆発生時間TM1の差異は燃料FUELの性状が異なることに起因するものであると特定されるので、燃料FUELの性状が異なることによるNVの悪化を速やかに検出することができる。
