ABSTRACT:
For a speed governing system for an internal combustion engine with self-ignition, which includes an electromagnetic final control element for influencing the injection quantity and a control unit having a governor for controlling the final control element, provisions are proposed which give the governor a high dynamic amplification in the range of a drop in the engine rpm, a dynamic amplification that drops from a higher value to a lower value in the range of a sudden drop of engine speed, that is, an rpm undercutting, and a flattened governor characteristic in the vicinity of the ends of the control range. A governor of this kind reacts very flexibly to changes in rpm and in particular does not enter a saturated state, and it adjusts to a new control state without disruptive reacceleration phenomena. A governor of this kind is particularly well suited for motor vehicles having a Diesel engine with a relatively large number of cylinders.
