Japanese Patent JPS6356416
Kind Code:
B2
Abstract:
An engine idling speed control system for an internal combustion engine which controls engine idling speed by adjusting the amount of intake air by-passing the throttle valve on the basis of the air-to-fuel ratio, in addition to the difference between the actual idling speed and the optimum idling speed determined on the basis of engine coolant temperature. The system according to the present invention comprises an air-to-fuel ratio determination section and an intake air calculation section for calculating the basic amount of intake air on the basis of the difference between the idling speed and the optimum idling speed and correcting the calculated basic amount of intake air on the basis of the air-to-fuel ratio.
