Abstract
【解決手段】過給機28と、アクチュエータを駆動することにより吸気弁2の開閉時期を変更するバルブタイミング変更機構4と、を有し、吸気弁閉時期を下死点よりも後に設定することによりミラーサイクルを実現する内燃機関1であって、バルブタイミング変更機構4が、前記アクチュエータを駆動する駆動手段である方向制御弁10の故障時には吸気弁閉時期が最進角位置となるように構成され、過給領域にあり、吸気弁閉時期の検出値が吸気弁閉時期の目標値に対して進角側に所定値以上進角した場合、前記検出値が前記目標値と一致している場合に比べて点火時期をリタードする。これによってバルブタイミング変更機構4の故障時には、点火時期をリタードするので、ノッキングの発生を防止することができる。
【選択図】図1
