Abstract

In a method of operating an internal combustion engine having at least two combustion chambers, each combustion chamber contributes torque to the total torque of the internal combustion engine, and the internal combustion engine is designed in such a way that a quantity of exhaust gas can be recycled into combustion chambers. The method has the steps: (a) detecting the torque contributions of at least two combustion chambers, then (b) changing the quantity of exhaust gas recycled into the combustion chambers, the torque contribution of which has been detected in step (a), then (c) detecting the torque contributions of at least two combustion chambers, the torque contribution of which has been detected in step (a), then (d) determining the change in the torque contributions as a result of the change in the quantity of recycled exhaust gas, and then (e) outputting a signal as a function of the change in the torque contributions.
