ABSTRACT:
A fuel injection device for supercharged engine including a supercharging blower located in the intake passage upstream of the throttle valve. The fuel injection device includes a fuel injection valve located downstream of the throttle valve. An air bleed system is provided so as to inject bleed air to the fuel injected from the fuel injection valve. The air bleed system includes a bleed air passage having an upstream end opening to the intake passage between the supercharging blower and the throttle valve so that any backflow through the bleed air passage can be prevented even under a heavy load engine operation.
