摘要： PROBLEM TO BE SOLVED: To prevent the generation of irritating odor of hydrogen sulfide H
2 S.
SOLUTION: In an exhaust emission control device, a SO
x trap catalyst 12, an oxidation catalyst 13, a particulate filter 14, an aqueous urea supply valve 17 and a NO
x selective reduction catalyst 16 are arranged in order from upstream in an engine exhaust passage. It is determined whether a discharge concentration of hydrogen sulfide H
2 S will become equal to or greater than a preset allowable concentration when SO
x is released from the SO
x trap catalyst 12. If it is estimated that the discharge concentration DN of the hydrogen sulfide H
2 S will become equal to or greater than the allowable concentration DNO when SO
x is released (S84: NO), an adsorbed ammonia amount adsorbed on the NO
x selective reduction catalyst 16 is reduced before SO
x is released so that the discharge concentration DN of the hydrogen sulfide H
2 S is less than the allowable concentration DNO when SO
x is released.
