摘要： PROBLEM TO BE SOLVED: To improve exhaust emission control performance while making exhaust gases cleaner even when a sulfur component absorbed in an NOx trap catalyst is eliminated. SOLUTION: The exhaust emission control device is constituted by the NOx trap catalyst 15, an air-fuel ratio adjustment means 31, a means 34 of performing desulfurization processing, and a leanizing execution means 35. The NOx trap catalyst 15 provided to the exhaust gas passage 13 of an internal combustion engine 1 absorbs nitrogen oxides and sulfur components in the exhaust gas in a lean atmosphere, and the air-fuel ratio adjustment means 31 adjusts an air-fuel ratio. The means 34 of performing desulfurization processing performs enriching of the air-fuel ratio of the exhaust gas a little more than a theoretical air-fuel ratio, and performs control so that the desulfurization processing is performed which releases the sulfur components from the NOx trap catalyst when predetermined desulfurization processing execution conditions are met. Then the leanizing execution means 35 performs control so that the air-fuel ratio is made leaner than the theoretical air-fuel ratio only for a predetermined lean time period when the desulfurization processing is performed by the means 34 of performing desulfurization processing.
