CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

PROBLEM TO BE SOLVED: To reduce cooling loss while reducing a generation amount of smoke.SOLUTION: A control device for an internal combustion engine includes: a fuel injection valve for injecting a fuel toward the inside of a cavity formed by denting an upper surface of a piston; a swirl control valve for changing a swirl speed by changing an opening by an intake passage; acquisition means for acquiring an operation state of the internal combustion engine; and control means for controlling the opening of the swirl control valve in such a manner that, in the operation state of the internal combustion engine acquired by the acquisition means, heat moving from a combustion gas to the piston becomes the minimum in a range where an equivalent ratio becomes smaller than 2 in a squish area.SELECTED DRAWING: Figure 6 【課題】スモークの発生量を低減しつつ冷却損失を低減する。【解決手段】ピストンの上面を凹ませて形成されるキャビティ内に向けて燃料を噴射する燃料噴射弁と、吸気通路で開度を変化させることでスワール速度を変化させるスワールコントロールバルブと、内燃機関の運転状態を取得する取得手段と、取得手段により取得される内燃機関の運転状態においてスキッシュエリアでの当量比が２よりも小さい範囲で燃焼ガスからピストンへ移動する熱が最小となるようにスワールコントロールバルブの開度を制御する制御手段と、を備える。【選択図】図６
