To make reduction in emission and reduction in power consumption compatible in an exhaust purification system in which an exhaust purifying catalyst is electrically heated.SOLUTION: An exhaust purification system for an internal combustion engine according to the present invention is applied to a hybrid vehicle which makes an EV travel after a system power supply is turned on, and comprises: an exhaust purifying catalyst; a heating body which is supplied with electric power to generate heat so as to heat the exhaust purifying catalyst; a battery which supplies electric power to an electric motor and the heating body; detection means which detects a passenger riding on the hybrid vehicle; and a control device which performs first control to control the supply of the electric power from the battery to the heating body so that the electric power is supplied to the heating body by a predetermined rate of active electric energy when the detection means detects the passenger riding on the vehicle and the power storage amount of the battery is larger than a second power storage amount.SELECTED DRAWING: Figure 5

    【課題】排気浄化触媒が電気加熱される排気浄化システムにおいて、エミッションの低減と消費電力の低減とを両立させる。【解決手段】本発明に係る内燃機関の排気浄化システムは、システム電源がオンにされた後、車両がEV走行されるハイブリッド車両に適用され、排気浄化触媒と、電力の供給を受けることにより発熱して排気浄化触媒を加熱する発熱体と、電動機及び発熱体に電力を供給するバッテリと、ハイブリッド車両への乗員の搭乗を検知する検知手段と、検知手段によって乗員の搭乗が検知されており、且つ、バッテリの蓄電量が第二蓄電量よりも多い場合に、活性電力量のうちの所定割合の電力量の電力が発熱体へ供給されるように、バッテリから発熱体への電力の供給を制御する第一制御を実行する制御装置と、を備える。【選択図】図5
