ABSTRACT:
A fuel injection pump for diesel engines has a reciprocating pressure piston which also rotates to distribute fuel to the individual injection valves. At idling and low engine load, the duration of injection is extended by permitting part of the fuel advanced by the piston to flow back to the fuel storage compartment. The fuel control mechanism adjusts the piston stroke to compensate for this lost fuel, thereby extending the duration of injection and reducing engine noise.
