ABSTRACT:
An air flow control device of an engine comprising an air flow control valve arranged in the intake passage and actuated by the vacuum operated diaphragm type drive apparatus. At the cranking of the engine, the air flow control valve is held in the closed state. When the engine speed exceeds a predetermined engine speed, for example, 400 rpm, a valve open signal for the air flow control valve is given to the vacuum operated diaphragm type drive device. After the valve open signal is given, during the valve opening delay period of the air flow control valve, an opening area of the idling speed control valve is increased.
