To provide a controller capable of using an upstream side fuel injection valve for engine starting while suppressing fuel storage during combustion at the initial stage of starting including first explosion, for an internal combustion engine comprising a port fuel injection valve, the upstream side fuel injection valve and a heater.SOLUTION: A controller controls an internal combustion engine comprising: a port fuel injection valve provided at an intake port connected to each cylinder; an upstream side fuel injection valve provided in an intake passage on the upstream side with respect to the branch position of an intake manifold connected to each of the intake ports; and a heater that heats fuel injected from the upstream side fuel injection valve. The controller executes a combined injection mode in which fuel injection from the port fuel injection valve is temporarily used when fuel injection from the upstream side fuel injection valve is started for starting the internal combustion engine.SELECTED DRAWING: Figure 4

    【課題】ポート燃料噴射弁と上流側燃料噴射弁とヒータとを備える内燃機関のために、初爆時を含む始動初期の燃焼時の燃料不足を抑制しつつ上流側燃料噴射弁をエンジン始動に利用できるようにした制御装置を提供する。【解決手段】制御装置は、各気筒に接続される吸気ポートに設けられたポート燃料噴射弁と、吸気ポートのそれぞれに接続される吸気マニホールドの分岐位置よりも上流側において吸気通路に設けられた上流側燃料噴射弁と、上流側燃料噴射弁から噴射された燃料を加熱するヒータと、を備える内燃機関を制御する。制御装置は、内燃機関の始動のために上流側燃料噴射弁からの燃料噴射を開始する際に、ポート燃料噴射弁からの燃料噴射を一時的に併用する併用噴射モードを実行する。【選択図】図4
