Abstract
This invention relates to the engine technical field, more particularly, an integrated fuel feed apparatus. The integrated fuel feed apparatus including a driving member, a plunger pumpdriven by said driving member, a fuel injector, a fuel intake memberand a fuel return member, with a return passagealways communicating the fuel intake memberwith the fuel return member, with some of the fuel in the return passagebeing ejected via the fuel injectorunder the action of the plunger pump, featuring that the driving member consists of a solenoid, a sleeveand a motion partwhich can reciprocate in the sleevedriven by the magnetic force of the solenoid, the aforesaid motion partgenerating a flow difference while reciprocating in the aforesaid return passage, thus achieving the fuel flow from the fuel intake memberto the fuel return member. The integrated fuel feed apparatus specified in the present invention can actively restrain the generation of fuel vapor and further actively discharge the fuel vapor generated therein.
