Abstract: The present invention relates to a method for controlling an air-fuel mixture for operating an internal combustion engine. A composition of the air-fuel mixture is determined by a first lambda sensor disposed in an exhaust gas channel of the internal combustion engine. If the first lambda sensor is not ready to operate, the composition of the air-fuel mixture is predetermined in pilot control. The present invention determines a measured torque of the internal combustion engine and a modeled torque for a lambda value of 1. If the measure torque and the modeled torque are different, a method for correcting the composition of the air-fuel mixture in the pilot control is suggested. Also, the present invention relates to a device for performing the method. The method and the associated device allow for improved pilot control of the air-fuel mixture if the first lambda sensor is not ready to operate, thereby reducing discharging of a harmful material.
