ABSTRACT:
An exhaust control apparatus applied to an internal combustion engine in which intake sides of a plurality of cylinder groups are connected to a common intake passage and exhaust sides thereof are connected to different exhaust passages, comprises an exhaust gas flow amount adjusting device for causing a flow amount of exhaust gas, which is discharged through each of the exhaust passages of the cylinder groups, to be changed, an exhaust gas flow amount difference estimating device for estimating a difference in an exhaust gas flow amount between the exhaust passages of the cylinder groups, and an exhaust gas flow amount control device for controlling the exhaust gas flow amount adjusting device so as to reduce the estimated difference in the exhaust gas flow amount.
