摘要： In an exhaust purification system having a urea addition device adding a urea aqueous solution to an NOx catalyst of selective reduction type provided in an exhaust passage in an internal combustion engine, a sensor detecting an ammonia concentration is provided at the downstream side of the NOx catalyst. During fuel cut, a predetermined amount of urea aqueous solution is added. Then, based on a sensor output obtained at this time, an abnormality in at least one of the urea addition device and the urea aqueous solution is detected. The addition of the urea aqueous solution during the fuel cut prevents reactive consumption between urea and NOx. The sensor output corresponding to the amount of the urea aqueous solution is obtained. This output condition is compared with a normal one to allow determination of whether or not an appropriate amount of urea aqueous solution of appropriate quality has been added.

摘要： 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.

摘要： An object is to estimate the degree of deterioration of an NOx catalyst with improved accuracy in an exhaust gas purification system having the NOx catalyst provided in an exhaust passage. According to the present invention, an NOx sensor is provided downstream of an NOx catalyst, and the difference between an estimated value of the NOx concentration in the exhaust gas in the exhaust passage upstream of the NOx catalyst and a detection value of the NOx sensor at a time when NOx in the exhaust gas is not removed in the NOx catalyst is calculated. In addition, in estimating the degree of deterioration of the NOx catalyst, the estimated value of the NOx concentration in the exhaust gas in the exhaust passage upstream of the NOx catalyst is corrected based on this difference, and the degree of deterioration of the NOx catalyst is estimated based on the difference between this corrected value and the detection value of the NOx sensor.
