ABSTRACT:
An idling speed control system is provided in an internal combustion engine which has an intake passage led to cylinders of the engine, a throttle valve installed in the intake passage, a bypass passage bypassing the throttle valve and an air-flow controller installed in the bypass passage for controlling the amount of air flowing in the bypass passage. The system comprises a first device which detects an engine torque which causes a fluctuation of rotation speed of the engine; and a second device which controls the air-flow controller in accordance with the detected engine torque.
