| titleOfInvention |
Apparatus purging exhaust gas of internal combustion engine |
| abstract |
According to the present invention, when the air-fuel ratio is changed to the rich side by the NOx emitting means, the exhaust atmosphere is set to an oxygen concentration lowering atmosphere, and when the NOx in the NOx catalyst is released, the exhaust gas is released into the exhaust passage at a predetermined time during the operation period of the NOx emitting means. A reducing agent for reducing the NOx discharged is further supplied by the reducing agent supplying means 33 so that the ratio of the released NOx and the reduced NOx is equal, and the NOx released from the NOx catalyst is reduced to exhaust the exhaust gas performance. It relates to a purification device. |
