| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | The exhaust gas purification apparatus of the present internal combustion engine includes a selective reduction type NO X catalyst device 2 capable of holding ammonia, and an occlusion reduction type NO X catalyst device 3 disposed upstream of the selective reduction type NO X catalyst device. , the air-fuel ratio of the exhaust gas flowing into the storage-reduction type NO X catalyst device in order to start the ammonia generation period is changed from a lean air-fuel ratio to the rich air-fuel ratio, storage reduction NO X catalyst to terminate the ammonia generation period in the exhaust purification system of an internal combustion engine that changes the air-fuel ratio of the exhaust gas flowing into the device from the rich air-fuel ratio to the lean air-fuel ratio, when the temperature of the occlusion-reduction type NO X catalyst device is lower than the set temperature, storage reduction NO X compared to when the temperature of the catalytic device is a set temperature or more, when a small amount of NO X held in the storage reduction NO X catalyst device, to start the ammonia generation period. |
