Abstract

PURPOSE:To control a number of revolutions very precisely by detecting an error between a target number of revolutions and an actual number of revolutions and an actual number of revolutions, parallelly moving an injection quantity pattern with this error as a parameter and controlling a number of revolutions at a time of partial load. CONSTITUTION:A target number of revolutions at a time of partial load is memorized in advance in a fuel injection pump control unit 4, which contains a micro computer, to detect an error between an actual number of revolutions. An injection quantity pattern (a governor pattern) is moved parallelly with this error as a parameter to control an intersecting point with a load curve on a target number of revolutions and also this fuel injection quantity order signal VS is added to an actuator 5 of an injection pump 1 to control fuel injection quantity. And, fuel is injected inside an engine cylinder through an injetor 6. By this, a number of revolutions can be controlled without being influenced by load size, irregularity of the injection pump 1, changes due to elapsed time, etc.
