Abstract

In order for the process and the device to function with as small as possible a number of sensors for operating parameters, a program map (20) is provided from which the intake air pressure (AL) of the charger (3, 5) is derived as a function of the charging pressure (PL), the engine speed (n), and a fuel quantity preset (QK) corresponding to the accelerator position, and there is a device (21) which determines a limit value (QKG1) for the fuel quantity (QK') metered to the engine (1) as a function of the intake air pressure (AL).
