ABSTRACT OF THE DISCLOSURE An electronic control type fuel injection apparatus comprises a vortex air-flow meter for sensing a suction air-flow rate by generating a frequency output according to a vortex air-flow rate depending upon a suction air-flow rate of air fed into an internal combustion engine; a control device for injecting the fuel by actuating an electromagnetic valve for a specific period substantially synchronized to the frequency output of said vortex air-flow meter; an air-cleaner placed in the upper- stream of said vortex air-flow meter; and a pressure sensor for sensing variation of pressure of the suction air fed into said vortex air-flow meter which is caused by said air-cleaner. Periods for actuating said electromagnetic valve are thereby controlled in accordance with the output of said pressure sensor.
