摘要： In a fuel injection apparatus for a multi-cylinder internal combustion engine (2l), a plurality of injection nozzles (l4) discharge fuel adjacent the engine inlet ports (l8), and a single fuel injector (l0) meters the fuel to all of the injection nozzles. The fuel injector (l0) comprises an injector base (28) having a plurality of fuel discharge passages (34) and an annular region (32) through which fuel is delivered to the fuel discharge passages, each of the fuel discharge passages being adaptable to direct fuel to one of the injection nozzles, the annular region including a valve surface (48), a single valve member (30) associated with the valve surface, the valve member being adapted to engage the valve surface to preclude fuel delivery to the fuel discharge passages, a solenoid (52) adapted to disengage the valve member from the valve surface to permit fuel delivery to the fuel discharge passages, characterised by air valve means (58, 64, 66) for controlling flow of air to the fuel discharge passages (34) and being adapted to preclude air flow to the fuel discharge passages when the valve member permits fuel delivery to the fuel discharge passages and to admit air to the fuel discharge passages when the valve member precludes fuel delivery to the fuel discharge passages.
