    摘要： An exhaust gas purification device having a NOx absorbent includes a by-pass passage for by-passing the NOx absorbent, an exhaust gas flow rate control portion for regulating both a flow rate of exhaust gas flowing to the NOx absorbent and the flow rate of the exhaust gas bypassing the NOx absorbent, and a reductant addition portion for adding reductant into an exhaust passage upstream of the NOx absorbent. In this device, when it is necessary to discharge sulfur components from the NOx absorbent, a temperature rise control is executed such that a temperature of the NOx absorbent becomes higher than a predetermined temperature. Next, a rich condition control is executed such that an air-fuel ratio of the exhaust gas flowing to the NOx absorbent becomes one of a substantially stoichiometric condition and a rich condition. The flow rate of the exhaust gas to the NOx absorbent during the temperature rise control is controlled so as to be higher than that during the rich condition control.

    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： The present detector for detecting sulfur components includes a storage portion for storing SOx and NOx in the exhaust gas passing through an exhaust passage, in which the more an amount of stored SOx increases, the more an amount of stored NOx decreases, and which does not release SOx but release NOx at a set temperature, and a temperature sensor, estimates the amount of stored SOx on the basis of a relationship between, after the storage portion becomes the set temperature by heating, a heating pattern of the storage portion and temperature change of the storage portion measured by the temperature sensor, and detects an integrated amount of SOx passing through the exhaust passage during a given period or an value on the basis of the integrated amount.
