用燃料噴射ポンプの燃料噴射量制御装置。 A fuel injection amount control member whose position changes according to a fuel injection amount request, a stopper means for regulating the position of the fuel injection amount control member, and a stopper means whose position is adjusted in response to intake pipe pressure downstream of a supercharger. In the fuel injection pump having a boost compensator to control, the stopper means has a first stop cam surface for controlling the fuel injection amount during non-supercharging operation and a second stop cam surface for controlling the fuel injection amount during supercharging operation. When the pressure is low, the boost compensator causes the fuel injection amount control member to cooperate with the first stop cam surface, while when the pressure is high, the boost compensator causes the fuel injection amount control member to cooperate with the second stop cam surface. A fuel injection amount control device for a diesel engine fuel injection pump that works together.
