Abstract (en)

[origin: DE19757893A1] Disclosed is a method for regulating the air-fuel mixture in an internal combustion engine, wherein the rate of combustion (WF) of the air-fuel mixture is detected as a measure of the above-mentioned proportion. To detect the above-mentioned measure, the direction of modification of the mean rate of combustion (WF) is detected in addition to the absolute value of the rate of combustion (WF) as a function of the air-fuel mixture in the above-mentioned absolute value.
