    摘要： An exhaust purification system is provided with an NOx storage reduction catalyst arranged in an exhaust passage and an SOx trap material arranged upstream of the NOx storage reduction catalyst and removes SOx contained in exhaust gas. A main flow path has a secondary flow path connected to it. In the secondary flow path, a removal device is arranged for removing the sulfur constituent contained in fuel. The secondary flow path includes an opening and closing device. When the SOx removal rate of the SOx trap material becomes a predetermined removal rate judgment value or less or the concentration of the SOx which flows into the SOx trap material becomes a predetermined concentration judgment value or more, at least part of the fuel flowing through a main flow path is made to flow into the secondary flow path and run through the removal device.

    摘要： An electronic control unit executing an algorithm so as to operate an exhaust purification system of an engine. The algorithm (1) commences a regeneration treatment by causing an amount of fuel supplied to a combustion process of the engine to increase so as to change an air-fuel ratio of exhaust gas of the engine from a first lean air-fuel ratio to a set rich air-fuel ratio and (2) causes uncombusted fuel to be supplied to a NOx catalyst device during at least one of: a first period in which an air-fuel ratio of the exhaust gas within the NOx catalyst device changes from the first lean air-fuel ratio to the set rich air-fuel ratio when the regeneration treatment is started; and a second period after an air-fuel ratio of the exhaust gas within the NOx catalyst device becomes a ratio indicating completion of the regeneration treatment.

    摘要： In an exhaust purification system of an internal combustion engine, comprising a NOX catalyst device, which can satisfactorily store NOX in the exhaust gas when the concentration of oxygen in the exhaust gas is high and can release the stored NOX and purify the released NOX to N2 by reducing materials in the exhaust gas when the concentration of oxygen is decreased as a regeneration treatment, the regeneration treatment is carried out to change a combustion air-fuel ratio from a lean air-fuel ratio to a set rich air-fuel ratio, and N2O reducing material is supplied to the NOX catalyst device during at least one of a first period set within a period in which an air-fuel ratio in the exhaust gas within said NOX catalyst device changes from the lean air-fuel ratio to the set rich air-fuel ratio when the regeneration treatment is started and a second period set within a period after an air-fuel ratio in the exhaust gas within the NOX catalyst device becomes the stoichiometric air-fuel ratio when the regeneration treatment is finished.

    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.
