ABSTRACT:
A fuel injection apparatus has an injector 4 for supplying fuel to an internal combustion engine 1, an air passage 35 having one end connected to the injector for atomizing the fuel injected therefrom and the other end connected to an air source, an air control valve 30 disposed in the air passage for controlling the quantity of air flowing therethrough, and a control unit 37 connected to the air control valve for controlling it in accordance with operating conditions of the engine. A pressure pump 40 may also be connected in the air passage for pressurizing the air therein, together with a pressure adjuster 42 disposed in a by-pass pipe 44 for controlling the pressure within the air passage, and a check valve 46 for preventing any pressurized air back flow.
