Abstract
In a method for controlling the air ratio lambda and for controlling the torque of an internal combustion engine, e.g. of a diesel engine, a fuel is supplied in at least two injection processes, including a main injection of a main injection quantity and a post-injection of a post-injection quantity, and the main injection quantity is influenced to control the torque and the post-injection quantity is influenced to control the lambda value. A corrective main injection quantity ascertained for the torque control is at least proportionally subtracted from the post-injection quantity.
