アイドル回転制御装置。 Detects an intake throttle valve installed in the engine's intake passage that controls the intake air flow rate, a bypass intake passage that bypasses the intake throttle valve, an on-off valve that opens and closes the bypass intake passage, and the actual air-fuel ratio of the engine. temperature detecting means for detecting the engine cooling water temperature or a temperature related thereto; temperature determining means for determining whether the detected temperature is equal to or higher than a predetermined value; and the air-fuel ratio detecting means. activation determining means for determining the activation state of the on-off valve; and valve driving means for driving the on-off valve to close when the temperature is determined to be equal to or higher than a predetermined value and the air-fuel ratio detecting means is determined to be sufficiently activated. An idle rotation control device for an internal combustion engine, comprising:
