摘要： To obtain an exhaust gas purification method for an internal combustion engine for detecting timing at which an inflow NOx amount flowing into an NOx absorption catalyst exceeds an NOx amount processable by the NOx absorption catalyst, and enriches the air/fuel ratio to prevent deterioration of the exhaust gas and maintain good fuel consumption. Based on an NOx amount absorbed in the NOx absorption catalyst and a maximum NOx absorption amount NOx of the absorption catalyst, a processable NOx amount processable by the NOx absorption catalyst per unit time is calculated and compared with the inflow NOx amount entering the NOx absorption catalyst per unit time, and when it is determined that the inflow NOx amount is greater, the air/fuel ratio is switched to rich.

摘要： An air/fuel ratio correction cylinder determining section 25 specifies, based on the peak phase, a cylinder for which an air/fuel ratio is to be corrected. A cylinder-specific air/fuel ratio correcting section in the form of respective cylinder correcting sections 31 through 34 corrects an amount of fuel to be supplied to a cylinder which becomes an air/fuel ratio correction target. A cylinder for which an air/fuel ratio deviates from the remaining cylinders is specified as a fuel amount correction target based on a change in the output value of the air/fuel ratio sensor.

摘要： An air-fuel ratio of exhaust gas flowing into a NOx absorber catalyst is compulsorily changed from a lean side to a rich side to release NOx absorbed by the NOx absorber catalyst. The Nox is reduced at the same time. If temperature of the NOx absorber catalyst is lower than a first predetermined temperature T1, temporaral change of the air-fuel ratio of the exhaust gas to the rich side for the purpose of releasing and reducing NOx is inhibited, and if temperature of the NOx absorber catalyst is higher than the first predetermined temperature T1 and lower than a second predetermined temperature T2, at the time of changing temporarily the air-fuel ratio of the exhaust gas to the rich side for the purpose of releasing and reducing NOx, timing of changing the air-fuel ratio and the set air-fuel ratio are changed depending on the temperature of the NOx absorber catalyst.
