Abstract

The invention is directed to a method and arrangement for controlling a self-igniting internal combustion engine. The arrangement includes at least one measured-value sensor, electronic control unit for forming a quantity signal for metering fuel, and a control unit for driving individual actuators for each cylinder. The actuators determine the quantity of fuel injected by the pump elements into the cylinders. Under specific conditions, a corrective unit is activated which determines corrective values specific to the cylinders for making the cylinders equal. The open-loop control unit applies the metering signal to the actuators in dependence upon the quantity signal and the corrective values.
