Abstract: Provided is a control device of an internal combustion engine for suppressing variation in the internal EGR amount among cylinders and improving the merchantability. A control device 1 of an internal combustion engine 3 has an ECU 2, wherein the internal combustion engine 3 includes an electric turbocharger 5 and first to fourth cylinders #1 to #4. The ECU 2 sets a target rotation change amount DN#i for a turbine 5b of the electric turbocharger 5 corresponding to each cylinder according to the operation state of the internal combustion engine 3 (Step 35), and controls a TC motor 5c of the electric turbocharger 5 in a control period, which includes an exhaust stroke in one combustion cycle of each cylinder, to match the target rotation change amount DN#i (Step 23).

Abstract: A control device for an internal combustion engine includes circuitry. The circuitry is configured to determine whether a running state of the internal combustion engine is in an auxiliary driving state in which an electric motor drives a compressor. The circuitry is configured to increase an opening degree of a waste gate valve when the running state is determined to be in the auxiliary driving state. The circuitry is configured to control a valve actuation phase variable mechanism to increase an overlap period in which a valve opening period of an intake valve and a valve opening period of an exhaust valve are overlapped with each other when the running state is determined to be in the auxiliary driving state.
