Abstract
In a method for enlarging the control range for equalizing injection quantity differences, in particular in internal combustion engines using multiple injections, if the maximum injection quantity of all the individual injections of an injector of the internal combustion engine is lower than the minimum quantity required for control for equalizing the cylinders, then the injection pattern is changed such that the injection quantity of at least one individual injection is greater than or equal to the required minimum quantity, without changing the torque output of the internal combustion engine.
