    Abstract: A method is disclosed for controlling a variable valve timing mechanism of an internal combustion engine having a plurality of cylinders, wherein, at a first operating point of the internal combustion engine, the fuel quantity which is fed in in each case is reduced successively for each cylinder until a predetermined unsmooth-running limiting value is reached. The variable valve timing mechanism is controlled with consideration of the cylinder-individual values for the fuel-quantity reduction at the first operating point.
