Abstract

A control device is proposed for controlling the air/fuel mixture and the ignition angle or ignition time in an internal combustion engine, in which case, during warming up with a desired or requested drive torque reduction, in addition to reducing the warming-up enrichment the ignition angle is adjusted in the direction of early and/or an increased secondary quantity of air is blown into the exhaust pipe. <IMAGE>
