| titleOfInvention | Exhaust gas purification system for internal combustion engine and exhaust gas purification method for internal combustion engine |
| abstract | An exhaust gas purification system for an internal combustion engine and an exhaust gas purification method for the internal combustion engine capable of purifying ammonia contained in exhaust gas after passing through a selective catalytic reduction device while maintaining NOx purification performance. . A part of an exhaust passage 11 on the downstream side of a selective catalytic reduction catalyst device 14 is divided into two branch passages 310 and 311, and ammonia adsorption / removal devices 300 and 301 are provided in the two branch passages, respectively. A flow path switching device 32 that switches the flow of the exhaust gas G between the two branch passages is provided at the branch point of the two branch passages. When exhaust gas is allowed to flow through one of the ammonia adsorption / removal devices, and the concentration D of the exhaust gas G passing through the exhaust passage 11 downstream from the junction of the two branch passages is equal to or higher than the first set concentration threshold D1. Then, the flow path switching device 32 is controlled to switch the flow of the exhaust gas G to the branch passage provided with the other ammonia adsorption / removal device. [Selection] Figure 5 |
