| titleOfInvention | Exhaust gas purification device for internal combustion engine and control method thereof |
| abstract | When the temperature of the reduction catalyst is lower than the reference temperature and the injection control of the reducing agent is stopped, when the exhaust gas temperature rises, the flow direction of the exhaust gas is changed from the forward direction to the reverse direction. Switching, the temperature of the reduction catalyst is quickly raised, and the reducing agent injection control is started early. An exhaust gas purifying device switches an exhaust gas flow direction to a forward direction from a particulate filter to a reduction catalyst, or to a reverse direction from the reduction catalyst to the particulate filter. A reducing agent injection control unit that performs injection control of the reducing agent from the reducing agent supply unit in a state where the temperature of the reducing catalyst is equal to or higher than a predetermined temperature, and the temperature of the exhaust gas when the temperature of the reducing catalyst is lower than the predetermined temperature. And a control unit for the exhaust gas flow path switching means for controlling the exhaust gas flow path switching means so that the flow direction of the exhaust gas is reversed.
