PURPOSE:To improve the low temperature starting performance of an apparatus for injecting fuel mixed with alcohol, by providing a main fuel pressure regulator and a starting fuel pressure regulator for pressure feeding the fuel having relatively high pressure to a starting injection valve. CONSTITUTION:A fuel feeding apparatus 2 for feeding fuel mixed with alcohol to an engine 1 is driven by a fuel pump 15 so as to distribute the mixture fuel in a fuel tank 8 through a fuel filter 12, a pulsation damper 14 and a delivery pipe 16 to a main injection valve 18 provided for every cylinder. In said apparatus 2, a fuel starting tube 19 branched from a fuel tube 10 is provided so as to feed the fuel through a check valve 20 and a fuel storage tank 21 to a starting injection valve 22 mounted on a surge tank 23. Furthermore, a main fuel pressure regulator 25 is provided at one end of the delivery pipe 16 and a starting fuel pressure regulator 27 having a higher setting pressure than that of the main fuel pressure regulator 25 is provided in the fuel storage tank 21. |
