Exhaust gas purification device for internal combustion engine |
| abstract |
(57) [Summary] [Purpose] Each NOx absorbent is used with its NOx purification rate at its peak. [Configuration] N when the air-fuel ratio of the inflowing exhaust gas is lean A NOx absorbent that absorbs Ox and releases the absorbed NOx when the oxygen concentration in the inflowing exhaust gas decreases A plurality of NOx absorbents 17, 20, and 23 having different temperature regions where the purification rate reaches a peak are arranged in the engine exhaust passage. The exhaust gas having a high temperature is sent to the NOx absorbent 17 having a peak NOx purification rate when the temperature is high, and the exhaust gas having a low temperature has a peak NOx purification rate when the temperature is low. Sent to. |
