摘要： An exhaust purification system of an internal combustion engine includes an NOX storage reduction catalyst device which is arranged in an engine exhaust passage. The NOX storage reduction catalyst device stores SOX simultaneously with NOX. When the stored SOX amount exceeds a predetermined allowable amount, the SOX is made to be released by SOX release control which raises the temperature of the NOX catalyst device to the SOX releasable temperature, then makes the air-fuel ratio of the exhaust gas which flows into the NOX catalyst device the stoichiometric air-fuel ratio or rich. The NOX catalyst device has a residual SOX storage amount which finally remains even if performing SOX release control depending on the temperature of the NOX catalyst device when performing SOX release control. The system uses the residual SOX storage amount of the current SOX release control as the basis to calculate the SOX release speed at each timing in the current SOX release control.

摘要： An engine with an exhaust passage in which a catalyst purifying NOx and an NOx adsorbent adsorbing NOx in an exhaust gas are arranged successively from the upstream side. After engine startup until the catalyst is activated, the NOx in the exhaust gas is adsorbed at the NOx adsorbent. NOx adsorbed at the NOx adsorbent is removed by dissolution by supplying a solvent from an injector. After the catalyst is activated, the solvent containing the NOx removed by dissolution is sprayed from an injector and the NOx contained in the sprayed solvent is purified by the catalyst.
