Abstract (en)
A fuel injection pump (1) with a simple structure that is able to respond to the demands of an engine by enabling both the pilot injection amount and the interval between pilot injection and main injection to be varied in accordance with the load (fuel injection amount). In the fuel injection pump, formed on the outer surface of the plunger is a pilot spill slit (32) that communicates with the fuel suction and discharge hole (26) of the plunger, a pilot injection cutoff port (33) is formed in the control sleeve (18) in a position in the axial direction that corresponds to the pilot spill slit (32), separately from the main injection cutoff port (30), and the angle of inclination from the horizontal of the pilot spill slit (32), and the mutual angle of inclination between the upper (32A) and lower edges (32B) of the slit, can be adjusted. <IMAGE>
