Abstract

The present subject matter relates to method for lambda and ignition angle control for a combustion in an internal combustion engine having at least one cylinder, wherein an optimized air-fuel ratio or an optimized ignition angle is determined from a characteristic, with which an estimated value for a torque is determined and which is based on an evaluation of a speed of a crankshaft in the internal combustion engine.
