摘要： PROBLEM TO BE SOLVED: To quickly and correctly perform deterioration determination of a storage reduction type NOx catalyst.SOLUTION: This catalyst deterioration determination system includes a determination device. The determination device performs first reduction agent supply in which reduction agent is supplied from a supply device while a control device controls an amount of reduction agent to make an air-fuel ratio of exhaust be a rich air-fuel ratio, and then performs second reduction agent supply in which the reduction agent is supplied from the supply device while the control device controls the amount of reduction agent to make the air-fuel ratio of the exhaust be the rich air-fuel ratio. When a detection value of an NHdetection device in the second reduction agent supply is less than a threshold value, the determination device determines that the NOx catalyst is deteriorated. When the detection value is the threshold value or more, the determination device determines that the NOx catalyst is normal.
