ABSTRACT:
A groove having a helix angle of zero or more is formed in the plunger of a diesel injector pump, the groove extending along and in association with the port-closing edge of the plunger and along at least a portion of the length of such port-closing edge. The groove interacts with the port that is associated with the port-closing edge to provide, in each of a succession of plunger strokes, initial fuel injection at feed rates lower than those which would obtain in the absence of the groove but without any loss of initial injection pressure, or without substantial loss of such pressure.
