Abstract
In an assist-air type fuel injection device for an internal combustion engine in which an assist-air for atomizing fuel is supplied toward an injected fuel on the lower stream of a nozzle hole of a fuel injection valve, a pressure detection part for detecting a pressure of the above assist-air is provided at the fuel injection valve, and the pressure of the assist-air detected at the above pressure detection part is supplied as a signal pressure to a pressure regulator for regulating a fuel supply pressure to the fuel injection valve. Without being affected by the assist-air pressure, a fuel flow rate can be stabilized, whereby control accuracy of the fuel injection amount can be maintained favorably.
