ABSTRACT:
A fuel injection pump for internal combustion engines in which to control the fuel injection quantities with the internal combustion engine cold, a first control edge is provided. For controlling the start of fuel injection with the internal combustion engine hot, a second control edge and a third control edge are provided. Assigned to respective control edges are provided a first and second oblique control edge, by means of which an effective pump piston feed stroke is controlled according to the rotary position of the pump piston. To switch off the internal combustion engine, in the region of transition from the first control edge to the second control edge the assignment of this second control edge to the second oblique control edge is provided in such a way that injection ceases on account of an overlap with a control port. This measure is assisted by an additional longitudinal groove which, in this rotary position, is in overlap with an additional control port, this additional longitudinal groove being the extension of a longitudinal groove, via which a pump working space is relieved during the operation of the internal combustion engine and after a reopening of the control ports by the oblique control edges.
