ABSTRACT:
A fuel injection apparatus with which energy for driving the high pressure fuel pumps of the apparatus by proper operation of the high pressure fuel pumps in order to reduce waste energy, and a method of operating an engine equipped with the apparatus, are provided. The apparatus is provided with a controller which allows some of the plurality of high pressure fuel pumps to be made inoperative in discharging fuel to the common rail by controlling the electromagnetic valves of said some of the pumps so that the plunger rooms of said some of the pumps are communicated to a fuel feed line for feeding fuel to the plurality of the pumps when the engine is operated with small/medium fuel injection quantity of smaller than a certain quantity.
