Abstract
A fuel feed apparatus of an internal combustion engine comprises: a passage member which is formed with a fuel passage serving to direct fuel injected from a fuel injection valve toward respective intake valves of the internal combustion engine, assist air passage through which assist air is jetted so as to cross the fuel injected from the fuel passage, and a cylindrical guide portion serving to regulate a spray cone angle of the fuel when the assist air is jetted from the assist air passages; and an interrupter device for interrupting the supply of the assist air to the air assist passages in accordance with the operating condition of the internal combustion engine, so that sprays of fuel directed to the plurality of intake valves individually are formed by the fuel passage when the interrupter device cuts off the assist air, while a single spray of fuel atomized by the assist air the spray cone angle of which is regulated by the guide portion is formed when the interrupter device allows the assist air to be supplied.
