Abstract

A method and a device for controlling an internal combustion engine are provided, in which method and device a deviation value is determined based on the comparison of a variable characterizing the combustion process in at least one cylinder with a corresponding setpoint value for this variable. Based on the determined deviation value, a first manipulated variable of a first actuator for influencing the start of activation is adjusted. Furthermore, based on the first manipulated variable, a second manipulated variable of a second actuator for influencing the air mass is adjusted.
