    • PROBLEM TO BE SOLVED: To provide an exhaust emission control system for an internal combustion engine capable of preventing slip of a reducing agent from a selective reduction catalyst without deteriorating NOx purification performance or uselessly consuming the reducing agent.SOLUTION: This exhaust emission control system comprises: first and second selective reduction catalysts purifying NOx in exhaust and adsorbing the NH, under the presence of NH; and a urea injection device injecting urea water to an exhaust pipe upstream of the first selective reduction catalyst. In this exhaust emission control system, it is determined whether the first selective reduction catalyst is in a temperature rise state. When it is determined that it is in the temperature rise state, an injection amount of the urea water from the urea injection device is reduced to a limited supply amount (GUREA_ORD-ΔST, GUREA_ORD×0.5, GUREA_ORD×0.3) greater than 0, and opening of an EGR valve is corrected to opening (VO_CLO) at the same side as the opening during the normal control to increase a NOx emission amount of the engine as compared with that during normal control.

    • PROBLEM TO BE SOLVED: To provide a catalyst degradation determination device that can determine degradation of a selective reduction catalyst with high precision, and can also suppress a temporary decline in purification performance involving this determination. SOLUTION: An exhaust purification system includes: a urea injection device; an ammonia sensor determining occurrence of an ammonia slip; and an ECU. By controlling the urea injection device, with respect to the selective reduction catalyst in such a state that an storage amount is maximum, the exhaust purification system reduces the storage amount thereof by a reduced-amount DST NH3_JD for detection, and then increases the amount until the ammonia slip is determined to occur. Then, degradation is determined based on the time when the slip determination flag F NH3_SLIP is set to "1", when the storage amount is increased or decreased. In this case, the reduced-amount DST NH3_JD for detection is set to a value that is larger than a storage capacity of the selective reduction catalyst in a degraded state and smaller than a storage capacity of the selective reduction catalyst in a normal state.
