Abstract

A control device for an internal combustion engine adjusts the flow rate ratio between an amount of exhaust gas flowing to an exhaust gas recirculation cooler (24) and an amount of exhaust gas flowing to a bypass passage (26), which bypasses the exhaust gas recirculation cooler (24), such that the amount of exhaust gas flowing to the exhaust gas recirculation cooler (24) becomes zero during (i) a predetermined period from a point in time at which the exhaust gas recirculation operation shifts to execution, (ii) a period in which fuel cut is performed and the bed temperature of a catalyst is lower than a predetermined overheat temperature, or (iii) a period in which the flow rate of refrigerant flowing to the exhaust gas recirculation cooler is lower than a predetermined flow rate and the temperature of the refrigerant is lower than a predetermined first temperature.
