ABSTRACT:
A fuel injection apparatus having a plurality of high pressure fuel injection pumps for supplying fuel to a common rail, of which amounts of fuel discharge can be controlled by a fuel supply amount adjusting device of simple and reliable construction. The fuel supply amount adjusting device is provided to fuel feed passages for feeding fuel to the plunger rooms. The adjusting device includes a spool valve device for varying opening area of each of passages for introducing fuel into each of the plunger rooms by sliding a spool fitted slidably in a spool valve case, a spool drive device for sliding the spool, and a controller for controlling the spool drive device so that the spool is slid to a position at which the opening area coincide with area required depending on engine operating conditions.
