Abstract

The invention is directed to an apparatus for influencing control quantities of an internal combustion engine by means of which vibrations of the entire vehicle in the lower engine speed range, particularly at idling, are to be eliminated. This is accomplished by allocating to each cylinder a regulating unit which regulates the control quantities influencing the respective cylinder, such as fuel metering, exhaust gas recirculation, start of injection, duration of injection, air/fuel ratio, ignition time point, et cetera, for the smoothest possible running condition.
