| titleOfInvention | Exhaust gas purification control system for internal combustion engine |
| abstract | In an exhaust system of an internal combustion engine having a selective reduction type NOx catalyst in an exhaust passage and a upstream catalyst having a property of occluding or adsorbing a sulfur component upstream thereof, when eliminating sulfur poisoning of the upstream catalyst, It is avoided as much as possible that the selective reduction type NOx catalyst falls into a sulfur poisoning state and the NOx purification performance is lowered. In the exhaust system of the internal combustion engine, it is determined that the conditions for executing a recovery process for raising the temperature of the front catalyst and removing sulfur oxides occluded or adsorbed by the front catalyst are satisfied. When the amount of ammonia estimated to be adsorbed on the selective reduction type NOx catalyst is less than a predetermined amount, the ammonia adsorption amount is reduced to at least the predetermined amount by supplying ammonia to the selective reduction type NOx catalyst. After increasing the volume, the recovery process is executed. [Selection] Figure 3 |
