Abstract
In a system and method for equalizing fuel-injection quantities among cylinders of an internal combustion engine, angular acceleration is measured during the combustion process of each cylinder of the internal combustion engine. The individual measured values of the angular acceleration are compared to one another. In case of deviations between the individual measured values, the fuel-injection quantity is altered in a way that allows for the deviations to be compensated.
