Abstract: To provide a control device of an internal combustion engine which can shorten a time necessary for a finish of an update of a learning value.SOLUTION: A control device 30 comprises a fuel quantity control part 130 for adjusting a fuel quantity supplied into a cylinder by feedback control for setting an air-fuel ratio deviation as an input, a target air-fuel ratio adjustment part 120 for alternately repeating lean period processing and rich period processing, and a learning value update part 140 for updating a learning value X for compensating the constant displacement of an air-fuel ratio AF. When an absolute value of an oxygen quantity deviation DOA is equal to a determination value or smaller, the learning value update part 140 updates the learning value X only when either of the lean period processing and the rich period processing is switched to the other. On the other hand, when the absolute value of the oxygen quantity deviation DOA is equal to the determination value or larger, the learning value update part 140 updates the learning value X at both the changeover of one processing to the other processing, and the changeover of the other processing to the one processing.SELECTED DRAWING: Figure 2
