An exhaust gas purification apparatus for an internal combustion engine (1), the exhaust gas purification apparatus includes a catalyst (40), a reducing agent supply mechanism (200), a dispersion plate (60), and a control unit (80). The catalyst (40) is configured to purify exhaust gas by adding a reducing agent. The reducing agent supply mechanism (200) is configured to add the reducing agent into an exhaust passage (26). The dispersion plate (60) is provided in the exhaust passage (26) and is configured to disperse the reducing agent upstream of the catalyst (40). The control unit (80) is configured to execute addition of the reducing agent by the reducing agent supply mechanism (200), and the control unit is configured to prohibit the addition of the reducing agent when a temperature of the dispersion plate (60) is lower than a predetermined temperature. |
