料噴射装置。 a flow path that sends a predetermined flow rate of fuel from a fuel supply source via a constant flow rate supply means and returns to the fuel supply source via an orifice; and a flow path branched from the flow path between the constant flow rate supply means and the orifice. and a flow path for injecting fuel at a discharge flow rate, and measures the discharge flow rate so as to balance the pressure difference detected by the air flow sensor with the fuel pressure difference before and after the orifice, thereby keeping the air-fuel ratio of the mixture constant. In the fuel injection device, the fuel control means is arranged for each cylinder of the engine, and each fuel control means is connected to the constant flow supply means through a jet. A multi-point fuel injection device characterized by:
