CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE, CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE, AND STORAGE MEDIUM

In a control device for an internal combustion engine, in the case that an intake air amount is calculated based on a flow rate signal, there is carried out a catalyst protection control based on an acquired exhaust gas temperature and a first predetermined temperature, and in the case that an intake air amount is calculated based on a pressure signal, there is carried out the catalyst protection control based on the acquired exhaust gas temperature and a second predetermined temperature that differs from the first predetermined temperature.
