Volumetric metering equipment, for use in metering the volume of fluid pumped through one or more injectors (42) by a fuel injection pump, has a controller (60) which serves to cause a number of injections to be disregarded immediately following the change in the lines (38, 36 and 50), including the drain line (50), which are open to a metering unit (10) of the equipment, in dependence upon the average volume of fluid delivered to the metering unit (10) per injection immediately before, at or immediately after the time of the change. <IMAGE> |
