PROBLEM TO BE SOLVED: To provide an internal combustion engine idle operation adjustment apparatus capable of converging an idle rotation speed into a target value at an early timing even before the complete warm-up of an internal combustion engine. ! SOLUTION: An engine control device 10 for an internal combustion engine 101 provided with a water temperature sensor 122 detecting a temperature of cooling water of the internal combustion engine 101, and a crank angle sensor 121 detecting a rotation angle of a crankshaft, comprises a memory unit 21 storing an adjustment value of a target value of an opening of a throttle valve 116 in response to the temperature of the cooling water for setting an engine rotation speed to a target rotation speed when the internal combustion engine 101 is in an idle operation state and before complete warm-up, detects the engine rotation speed on the basis of sensor information on the crank angle sensor 121, adjusts the target value of the opening of the throttle valve 116 so |
