CONTROLLER FOR INTERNAL COMBUSTION ENGINE

A controller is configured to control an internal combustion engine. The internal combustion engine includes an intake passage, a motor, a forced-induction device, a flow rate adjusting valve, a crankcase, and first and second passages connected to the crankcase. The forced-induction device uses the motor to drive a compressor wheel provided in the intake passage. The flow rate adjusting valve is provided downstream of the compressor wheel in the intake passage. The controller includes processing circuitry configured to execute scavenging control that drives the motor with the flow rate adjusting valve closed in a case where engine shutdown is performed.
