摘要： The present invention is intended to improve a SOx reduction rate which is a ratio of an amount of SOx reduction with respect to an amount of SOx occlusion in SOx poisoning recovery processing. In the present invention, in the SOx poisoning recovery processing in which the SOx occluded in an NOx storage reduction catalyst is reduced by decreasing the air fuel ratio of an exhaust gas flowing into the NOx storage reduction catalyst to a predetermined air fuel ratio in a repeated manner, the length of a period in which the air fuel ratio of an exhaust gas flowing into the NOx storage reduction catalyst is decreased is made longer in a relatively early time during the processing than in a relatively late time during the processing.

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： A wall flow type particulate filter is arranged inside the exhaust passage of an internal combustion engine where combustion is performed under an excess of oxygen. The particulate filter carries a solid acid. The solid acid has an acid strength which is higher than the acid strength of sulfurous acid and lower than the acid strength of sulfuric acid. To remove the ash from the particulate filter, ash atomization processing for rendering the state of the particulate filter a state where the exhaust gas which flows into the particulate filter is lowered in concentration of oxygen and the particulate filter is raised in temperature is temporarily performed.
