Abstract (en)

[origin: WO2012079935A1] The method relates to a method for controlling and adapting an air/fuel ratio of an air/fuel mixture in an internal combustion engine (2), in particular in a spark ignition engine; having the following steps: - providing an actual lambda value (LambdaAct), which specifies a current air/fuel ratio value, and a setpoint lambda value (LambdaSetp), which specifies a desired air/fuel ratio value; - determining as a function of the actual lambda value (LambdaAct) a correction value for controlling and adapting the actual lambda value (LambdaAct) to the setpoint lambda value (LambdaSetp), wherein the correction value corresponds, as a function of the deviation of the actual lambda value (LambdaAct) from the setpoint lambda value (LambdaSetp), to a charge correction value (CCorr2) for applying a variable which influences the air charge of the internal combustion engine (2) or a fuel correction value (FCorr) for applying a variable which influences the fuel quantity to be injected in the internal combustion engine (2).
