Abstract

A device and a method are described for controlling an internal combustion engine, in which a control deviation and a governor are allocated to each cylinder of the internal combustion engine, each governor preselecting a cylinder-specific triggering signal on the basis of the allocated control deviation. Cylinder-specific actual values are ascertained on the basis of a signal from a sensor arranged in the exhaust train and are compared to a setpoint value. Triggering signals for the cylinder-individual control of the fuel quantity and/or air quantity are preselected on the basis of the comparison.
