Exhaust gas purification system for internal combustion engine |
| abstract |
An exhaust gas purification system for an internal combustion engine is provided that can suppress the reduction agent that has been trapped from being discharged to the downstream side even when there is a sudden temperature change in a selective reduction catalyst. An exhaust purification system includes a first selective reduction catalyst that purifies exhaust gas in the presence of ammonia, a urea injection device that injects urea water upstream of the first selective reduction catalyst, and a first selective reduction catalyst. Based on the estimated temperature T CAT_PRE , the catalyst temperature predicting unit 53 that estimates the predicted temperature corresponding to the temperature after the predicted time TPRE from the present time, the storage amount estimating unit 56 that estimates the storage amount of the selective reduction catalyst, and The target storage amount calculation unit 55 that calculates the target storage amount, and the storage injection amount that is a part of the urea injection amount G UREA by the urea injection device so that the estimated storage amount ST UREA becomes the target storage amount ST UREA_TRGT And a storage injection amount calculation unit 52 that calculates G UREA_ST .
