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 exhaust gas purifier for an internal combustion engine which is capable of detecting the deterioration degree of an NOx catalyst making use of a time elapsed from the time when the air-fuel ratio of exhaust gas flowing into an NOx absorber catalyst is made rich to the time when the air-fuel ratio of exhaust gas flowing out from the NOx absorber catalyst becomes rich. When the time required for a change in the output level of an air-fuel ratio sensor is shorter than a predetermined time, the time required for the change in the output level of the air-fuel ratio sensor is lengthened by reducing the rich degree at the time of rich operation, thereby judging the deterioration degree of the NOx absorber catalyst with accuracy.
