This invention relates to an electrically operated fuel injection apparatus comprising a fuel inletting device (110), a fuel pumping device (112) and a fuel injecting device (113). Fuel from the said fuel inletting device (110) is pumped by the said fuel pumping device (112) and then is injected out by the said fuel injecting device, wherein the said fuel pumping device (112) includes an operating coil (13), a returning coil (12) and a driven device (114) driven by the magnetic fields of these two coils; the magnetic loop induced by the said operating coil (13) excites the said driven device 9114) so as to inject the fuel by the said fuel injecting device (113), and the magnetic loop induced by the said returning coil (12) excites the said driven device to return back to its original position.
