Abstract

The invention relates to a method for restarting an internal combustion engine, in which a first cylinder (ZYL1) has a low air level and a second cylinder (ZYL2) has a high air level, and wherein a predefined speed threshold value (ns) is selected as a function of said air levels. A method for the restart is selected and carried out as a function of a comparison of the determined speed (n) of the internal combustion engine with the predefined speed threshold value (ns).
