PROBLEM TO BE SOLVED: To set optimum motoring time after stoppage of an internal combustion engine that can use alcoholic fuel.SOLUTION: A control device of an internal combustion engine 1 that can use alcoholic fuel includes: acquisition units 20, 34 for acquiring alcohol concentration of fuel; a motor for driving the internal combustion engine; and a control unit 20 for controlling the internal combustion engine and the motor. When a parameter is equal to or less than a given value, the parameter increasing with operation time of the engine from a low-temperature start to the stop or with an increase in the operation time, the control unit causes the motor to motor the internal combustion after stopping the internal combustion engine, and sets the motoring time to be shorter when the alcohol concentration of the fuel obtained by the acquisition unit is relatively high than when the alcohol concentration is relatively low. |
