Abstract

PURPOSE: To accomplish an accurate control of the engine idling speed to a designed value regardless of the kind of engine lubricant by controlling electric current through a solenoid valve according to a functional voltage.
CONSTITUTION: In engine idling when a throttle valve 16 is fully closed or in the proximity of the full opening, the opening of an air control valve 30 is controlled in a closed loop by a closed loop control circuit in an electronic air control unit 60. The control unit 60 receives a signal from a sensor 19 and an air conditioning switch 23 to allow a function generator 60a to produce a functional voltage V. The sensor 19 is to detect the temperature on an engine cooling water. The voltage V varies with the change in the temperature of the engine cooling water, i,e., the heating condition of the engine 10 when the switch 23 is turned on.
