Abstract
The present invention achieves an increase in the amount of vapor that is expelled, stabilized fuel injection and improved starting characteristics in a fuel injection pump. In an electromagnetically driven fuel injection pumpwhich allows fuel to escape into the return passagein the initial region of the pressure-feeding stroke of the plunger, and which pressure-feeds fuel into the injection portin the later region of the pressure-feeding stroke, pulse powering of the coilthat does not lead to the injection of fuel, i.e., pulse powering which is such that the plungerperforms a reciprocating motion through the initial region, is performed when the engineis in an idle operating state, or in a state in which the engineis re-started after being stopped immediately following high-load operation. As a result, vapor can be expelled with good efficiency, and the flow rate of the circulated fuel is increased so that the cooling effect is also increased, thus causing the generation of vapor to be suppressed as well, so that the starting characteristics or re-starting characteristics are improved.
