Abstract
An exhaust probe is arranged on an internal combustion engine with multiple cylinders and the injection valves provided for the cylinders measure the fuel. The exhaust probe is arranged on an exhaust manifold, and the measured signal is characteristic of the air/fuel ratio in the corresponding cylinder. The measured signal is recorded at a given crankshaft angle with relation to a reference position for the piston and allocated to the corresponding cylinder. A set parameter for adjustment of the air/fuel ratio in the corresponding cylinder is generated depending on the measured signal recorded for each cylinder. The given crankshaft angle is adjusted depending on a value criterion which depends on a uneven running of an output shaft from the internal combustion engine.
