PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine that can suppress the deterioration in exhaust gas characteristics and the occurrence of engine stall, by optimizing air-fuel ratio control at the start of the internal combustion engine.SOLUTION: An ECU acquires an oil temperature, a water temperature and a soak time (step S11), and determines whether vapors have been produced in a fuel supply device on the basis of a vapor production prediction map (step S12). When the ECU determines that vapors have been produced in the fuel supply device, the ECU reduces a feedback gain (step S13). Subsequently, the ECU 50 predicts a vapor production time (step S14), and, when the ECU determines that a vapor production end time has been reached (YES in step S15), executes normal feedback control (step S16). |
