For each of banks and, the fuel injection amount is changed under a consistent operating condition in which scavenging occurs, and the scavenging amount is calculated from the exhaust gas air fuel ratio at the time when the indicated torque based on the detection value of an in-cylinder pressure sensor is at the maximum. If the scavenging amount differs between the banks, the valve overlapping period of a relevant one of the banks and is controlled to reduce the difference of the scavenging amount between the banks. |
