Abstract
A fuel injection control apparatus provided with an air blast valve having a nozzle opening connected to an engine-drive air pump through a compressed air passage, a fuel injector for injecting fuel in the compressed air passage, and an opening and closing valve for controlling the opening and closing of the nozzle opening. When the compressed air pressure in the compressed air passage is lower than a set pressure, fuel is injected from the fuel injector during the opening of the opening and closing valve and the injected fuel is ejected from the nozzle opening by inertia force. When the compressed air pressure in the compressed air passage is above a set pressure, the fuel is injected from the fuel injector during the closing of the opening and closing valve and the injected fuel is ejected from the nozzle opening by compressed air during the opening of the opening and closing valve.
