Abstract
A control device of an internal combustion engine, includes: a boost pressure detector to detect a boost pressure of air pressurized by a compressor of a supercharger including a turbine; and a processor configured to determine a rapid decrease in a target boost pressure; determine that an execution condition is satisfied in a case where the target boost pressure rapidly increases immediately after the rapid decrease is determined while the exhaust gas is refluxed; calculate a restriction opening control amount for an exhaust gas flow amount variable device to control a flow amount of the exhaust gas blown to the turbine so as to regulate a changing speed of an opening control amount to decrease an opening of the exhaust gas flow amount variable device when the execution condition is satisfied; and control the opening of the exhaust gas flow amount variable device according to the restriction opening control amount.
