CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

An internal combustion engine is provided with: an electric supercharger including an electric compressor; an EGR introduction port formed upstream of the electric compressor; a throttle valve A arranged upstream of the EGR introduction port; and a control device. A throttle valve B other than the throttle valve A is not arranged in the intake air passage. The control device is configured, in a non-supercharging region, to execute a first air flow rate adjustment processing that adjusts an intake air flow rate by adjusting the opening degree of the throttle valve A while driving the electric supercharger to cause a pressure ratio of the electric compressor to approach 1; and a second air flow rate adjustment processing that adjusts the intake air flow rate by adjusting the opening degree of the throttle valve A while not energizing the electric supercharger.
