Abstract

An internal combustion engine comprises an engine body, a filter provided in an exhaust passage of the engine body and trapping particulate matter in the exhaust, and a temperature sensor detecting a temperature of gas flowing cut from the filter. A control device controlling this internal combustion engine comprises a fuel cut control pan configured to perform fuel cut control stopping a supply of fuel to a combustion chamber of the engine body and a forced ending part configured to forcibly make the fuel cut control end even if a condition for performance of fuel cut control had stood based on a trend in change of temperature of the gas temperature detected by the temperature sensor.
