ABSTRACT:
A fuel-injection pump for diesel-engine injection system, comprising at least one cylinder-piston unit with an associated intake valve for the introduction of fuel delivered by an electrical supply pump, and a delivery duct. Electronic means are provided for modulating the electrical supply pump to vary the pressure of the fuel taken in by the cylinder-piston unit and consequently the bottom dead center position of the piston and hence the length of its pumping stroke.
