- 燃焼の際に点火プラグの電極を流れるイオン電流を検出する回路を介して電極を流れる電流を計測することのできる内燃機関の制御装置であって、
内燃機関を停止させる際、その停止の直前の時期に前記回路を介して計測された、点火プラグの電極を流れる電流の大きさが閾値を上回っている期間の長さ、または点火プラグの電極を流れる電流の計測値の時系列を、メモリに記憶して保持するとともに、
停止している内燃機関の始動を開始してから所定時間が経過しても始動を完了できない場合、直前に内燃機関を運転していたときに前記回路を介して計測されメモリに記憶保持したイオン電流の大きさが閾値を上回っている期間の長さに基づいて内燃機関における異常の存在箇所を推定することを特徴とする内燃機関の制御装置。
