abstract |
When the NOx SCR catalyst (15) deteriorates, the NOx removal efficiency increases with an increase in the catalyst temperature as indicated by the curves B1 and B2. When there is an irregularity in the amount or quality of aqueous urea solution that is supplied to the NOx SCR catalyst, the NOx removal efficiency decreases at a constant rate as indicated by the curve C. When the NOx removal efficiency is first within the region X2 and then brought into the region Y1, it is determined that the NOx SCR catalyst deteriorates. When the NOx removal efficiency is first within the region X2 and then brought into the region Y2, it is determined that there is an irregularity in the amount or quality of the aqueous urea solution that is supplied to the NOx SCR catalyst. |
