PROBLEM TO BE SOLVED: To provide a fuel injection control device of an engine mounted in a vehicle, capable of eliminating a delay of the fuel injection timing of a fuel injection valve from a reference value set initially due to the adhesion of engine oil or the like to the injection nozzle of the fuel injection valve, by exerting simple control.SOLUTION: The vehicle is a hybrid electric vehicle that includes an engine 10 and a drive motor 40 and that can be driven only by the drive motor 40, and a fuel injection control device of the vehicle executes a fuel injection timing correction control to advance the fuel injection timing of a fuel injection valve of the engine 10 from the reference value while keeping the engine 10 at a constant revolving speed, and to correct the fuel injection timing of the fuel injection valve with respect to the reference value in response to a difference between an engine output detected after advancement and a reference engine output corresponding to the reference value at the constant revolving speed.

    【課題】車両に搭載された、エンジンの燃料噴射制御装置において、燃料噴射弁の噴射口にエンジンオイル等が付着することによる該燃料噴射弁の燃料噴射時期の、当初に設定された基本値に対する遅れを、簡単な制御で解消する。【解決手段】上記車両を、エンジン10及び駆動モータ40を有しかつ該駆動モータ40のみにより駆動可能なハイブリッド車両とし、エンジン10を一定回転に保持させつつ、エンジン10の燃料噴射弁の燃料噴射時期を上記基本値に対して進角させるとともに、その進角後に検出されるエンジン出力と、上記一定回転での上記基本値に対応する基本エンジン出力との差に応じて、上記燃料噴射弁の燃料噴射時期を上記基本値に対して補正する燃料噴射時期補正制御を実行する。【選択図】図1
