PROBLEM TO BE SOLVED: To provide an internal combustion engine control device which can suppress a catalyst temperature from exceeding a heat resistant temperature even if fuel cut is executed immediately after a scavenge region.SOLUTION: An internal combustion engine control device includes a supercharger for supercharging intake air into a cylinder and a catalyst for purifying exhaust emitted from the cylinder. The internal combustion engine control device executes scavenge control for scavenging the inside of the cylinder when an operational region is in a scavenge region. The internal combustion engine control device stores a determination temperature in a normal time when the scavenge control is not executed, and suppresses a temperature increase of the catalyst when the temperature of the catalyst is higher than the determination temperature. Moreover, in scavenging when the scavenge control is executed, the determination temperature is changed into a lower temperature. |
