Abstract
A fuel injection pump having a timing piston shiftable for establishing the fuel injection timing, a servo valve piston for hydraulically positioning the timing piston, biased in the advance direction by a speed correlated fluid pressure, engine load responsive means acting through a compression spring to bias the servo valve piston in the retard direction, a bleed valve for establishing a regulated fuel pressure biasing the servo piston in the retard direction, the bleed valve being biased in its opening direction by the regulated pressure, and bleed valve control means responsive to continuous measurements of one or more operating parameters of an associated engine and acting through a compression spring to variably bias the bleed valve in its closing direction.
