An idle revolution control device includes a water temperature sensor, a filter means and a control means which is constituted with a central processing unit and an interface connecting the water temperature sensor and the central processing unit. The filter means functions to provide a time constant which provide a high response speed for a temperature variation toward a high temperature side and a low response speed for a temperature variation toward a low temperature side and to pass an output signal of the water temperature sensor with such time constant a predetermined time after an engine starts.
