abstract |
An object of the present invention is to determine whether a NO x purification rate has decreased due to deterioration of a NO x selective reduction catalyst or whether a NO x purification rate has decreased due to abnormalities in urea water. A NO x NO x removal efficiency NR when the selective reduction catalyst 15 is deteriorated accompanied not increased to increase the catalyst temperature TC as curve B1, NO x purification when there is abnormality in the supply amount and quality of aqueous urea The rate NR decreases uniformly as shown by the curve C. When the NO x purification rate NR becomes the region X 2 , catalyst deterioration occurs when the NO x purification rate NR further becomes the region Y 1, and when the NO x purification rate NR becomes the region Y 2 , there is an abnormality in the supply amount and quality of urea water. It is judged that there is. [Selection] Figure 3 |
