Abstract (en)

[origin: DE102005004441B3] The reporting process involves reporting a preset air-fuel ratio (LAMSP) in the combustion chamber, depending on at least one operating value of the engine. It also reports this ratio after filtering (LAMSPFIL) through a filter, the effect of which depends on conditions in the catalytic converter. It also reports a detected air-fuel ratio (LAMAV) in the combustion chamber, depending on a measuring signal from an exhaust gas probe. It reports the setting value by means of the regulator, depending on the filtered and detected ratios in the combustion chamber.
