| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | A hydrocarbon supply valve (16), an oxidation catalyst (13), an exhaust purification catalyst (14), and a NO X selective reduction catalyst (15) are arranged in this order from the upstream side in the engine exhaust passage. By reducing the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (14) with a predetermined period while maintaining lean, NO X is reduced in the exhaust purification catalyst (14), and the exhaust purification catalyst (14) NO X that has not been reduced in step NO is reduced by the ammonia adsorbed in the NO X selective reduction catalyst (15). The air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (14) is sometimes switched from lean to rich, and at this time, the ammonia generated in the exhaust purification catalyst (14) is adsorbed by the NO X selective reduction catalyst (15). |
