| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | Provided is a technique for suppressing emission of hydrogen sulfide (H 2 S) generated at the time of recovery from SOx poisoning into the atmosphere in an exhaust gas purification device for an internal combustion engine. A NOx catalyst (3) having oxygen storage capacity and reducing NOx stored in the presence of a reducing agent, oxygen storage means (7) downstream of the NOx catalyst (3), NOx catalyst (3) and oxygen storage means (7) , A second exhaust passage 2 a that is connected between the NOx catalyst 3 and the oxygen storage means 7 and does not pass through the oxygen storage means 7, a reducing agent supply means 9, and an SOx of the NOx catalyst 3. SOx poisoning recovery means 9 for recovering poisoning, and exhaust gas to the second exhaust passage 2a for a predetermined period from the start of SOx poisoning recovery by the SOx poisoning recovery means 9 to an increase in the amount of hydrogen sulfide released. Exhaust passage switching means 8 for circulating. [Selection diagram] Fig. 1 |
