PROBLEM TO BE SOLVED: To improve startability of an internal combustion engine.SOLUTION: A starter for an engine 2, provided with a motor generator 9 driven by electric power supplied from a driving battery 11 mounted in a vehicle 1 and starting the engine 2, is configured such that a starting-time fuel correction control unit 50 in an engine control unit 22 increases an injection amount of a fuel to the engine 2 at a time of starting the engine 2 when a state of health SOH of the driving battery 11 estimated by a hybrid control unit 20 falls to be equal to or lower than a threshold Sa.SELECTED DRAWING: Figure 1
【課題】内燃機関の始動性を向上させる。【解決手段】車両1に搭載した駆動用バッテリ11から供給された電力により駆動して、エンジン2を始動させるモータジェネレータ9を備えたエンジン2の始動装置であって、エンジンコントロールユニット22の始動時燃料補正制御部50は、ハイブリッドコントロールユニット20において推定した駆動用バッテリ11の電池劣化率SOHが閾値Sa以下に低下した場合に、エンジン2の始動の際におけるエンジン2への燃料噴射量を増加させる。【選択図】図1
