Abstract
A fuel injection system for an internal combustion engine introduces, via an air passage bypassing a throttle valve, a portion of intake air flowing in an induction system of the engine to an area where fuel is injected from a fuel injection valve, so as to facilitate atomization of the injected fuel. The air passage includes therein a flow control unit for opening and closing the air passage. During an engine idling, a total opening time of the air passage effected by the flow control unit is variably controlled for adjusting a supply mount of the intake air through the air passage so as to realize a target idling engine speed. As a result, the intake air fed through the air passage works not only to facilitate the atomization of the injected fuel, but also to control the idling engine speed to the target value.
