| 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 branch passage (31) having an ammonia adsorption / removal device (30) is provided in parallel with the exhaust passage (11) in the exhaust passage (11) downstream of the selective catalytic reduction catalyst device (14), and the flow of exhaust gas (G) is connected to the exhaust passage (11). A flow path switching device 32 that switches between the branch passages 31 is provided, and the concentration D of ammonia contained in the exhaust gas G that passes through the exhaust passage 11 downstream from the ammonia adsorption removal device 30 is equal to or higher than the first set concentration threshold D1. At some point, the flow path switching device 32 is controlled to switch the flow of the exhaust gas G from the exhaust passage 11 to the branch passage 31. [Selection] Figure 4 |
