Abstract

In special operating mode, such as, for example, warming up, acceleration, full load, the setting of the mixture is, as is known, performed by a control instead of a .lambda. adjustment. This can result in a lean mixture. This is avoided by the fact that the .lambda. adjustment remains switched on with a restricted range of adjustment during the special operating mode. It is superimposed on the pilot control and only acts in the direction of enrichment.
