ABSTRACT:
An idle control system for an automobile internal combustion engine includes an idle control unit for controlling the operation of an electromagnetically operated actuator. While the engine has a combustible mixture intake passage leading to the engine and a throttle valve operatively positioned inside the mixture intake passage for controlling the flow of a combustible air-fuel mixture towards the engine, the actuator is utilized to adjust either the effective cross sectional area of a bypass air passage leading from the air source to the mixture intake passage at a position downstream of the throttle valve or the opening of the throttle valve, to control the engine speed during idling to a predetermined value.
