摘要： The present invention provides an exhaust purification apparatus for an internal combustion engine which enables a decrease in NOx purification rate and possible ammonia slip to be inhibited. The apparatus includes an NOx catalyst, a urea aqueous solution addition valve serving as reducing agent adding means, and NOx sensors provided an inlet and an outlet of the NOx catalyst, respectively. When the bed temperature of the NOx catalyst is in a predetermined high-temperature region in which the amount of ammonia converted into NOx increases relatively and an NOx purification rate decreases relatively, the apparatus uses outputs from the NOx sensors to perform correction such that the actual addition amount of the urea aqueous solution addition valve reaches a target addition amount.

摘要： The purpose is to prevent ammonia from flowing out of a NOx selective reduction catalyst when an air-fuel ratio of exhaust gas flowing into a NOx storage/reduction catalyst decreases. An NSR catalyst, a NOx sensor, and an SCR catalyst are provided in an exhaust passage in sequence from an upstream side, and a control apparatus is further provided to determine an amount of ammonia supplied to the NOx selective catalytic reduction catalyst on the basis of a detection value of the NOx sensor. When the air-fuel ratio of the exhaust gas flowing into the NOx storage/reduction catalyst is set at or below a stoichiometric air-fuel ratio, an amount of ammonia supplied from an ammonia supply apparatus relative to the detection value of the NOx sensor is decreased so as to be smaller than when the air-fuel ratio of the exhaust gas is larger than the stoichiometric air-fuel ratio.
