Abstract
A multiple plunger fuel injection pump includes a pair of axially positionable interconnected control sleeves encircling each plunger for controlling the quantity and timing of fuel delivered by the plunger. Speed and load response actuators are operative to control the axial positioning of each sleeve of each pair of control sleeves. Adjustment means are provided for separately adjusting, during operation of the injection pump, the axial positioning of each sleeve to balance the timing and quantity of fuel delivered by each plunger with respect to the other plungers.
