In a multi-cylinder internal combustion engine in which, for fuel saving purposes during part-load operation, some of the cylinders (2) can be cut off by an interruption of the fuel supply to the respective cylinders and by the shutdown and closing of their inlet valves (6) and outlet valves (7) until the refiring of the cylinders (2) when higher operating loads of the internal combustion engine (1) are required, a smooth operating behavior of the internal combustion engine (1) during the changeover between the fired and the cut-off operation of the cylinders (2) is achieved by an additional compensating opening of the outlet valves (7) irrespective of the gas-exchange control times of the valves for fired cylinder operation.
