摘要:
A control device includes first means and second means for recirculating exhaust gas from an exhaust passage toward an intake passage. When first recirculated gas amount recirculated by first means for recirculating exhaust gas is changed to a target amount, the control device compensates for the difference of the first recirculated gas amount during a period from a start time of change to an end time of change by increasing or decreasing the second recirculated gas amount recirculated by second means for recirculating exhaust gas, according to a predetermined control pattern. When an actual amount of index related to the recirculated gas amount that is a constituent included in the exhaust gas and an amount of the constituent vary depending on total amount of the exhaust gas does not match a referential amount of the index, the control pattern is corrected to decrease the difference of the index that is a difference of the actual amount with reference to the referential amount.
