Abstract (en)
[origin: EP1336728A2] In an internal combustion engine (ICE) (10), an airflow sensor (14) signals to an electronic controller (18) to calculate a fuel proportion signal and trigger a fuel apportioning device (16) in an ICE intake pipe (12). Oxygen introduced/emitted in a preset time assumes a preset value so that combustion operates with rich/lean oxygen mixtures until an oxygen-sensitive Nernst sensor is triggered. An Independent claim is also included for a control device for carrying out the method of the present invention.
