Abstract (en)
A device for electronically controlling adjusting devices in an internal combustion engine in which the adjusting devices can be controlled, by comparing differentiated engine speed dependent signals with predeterminable threshold values, in such a way that shuddering oscillations of the internal combustion engine are counteracted. A time control is included which is initiated when the adjusting devices are actuated to perform fuel quantity modulation and which is arranged to switch off the fuel quantity modulation after an elapsed time period, whose value is dependent upon the prevailing operating conditions of the engine.
