Abstract
A control apparatus is proposed for a fuel metering system of an internal combustion engine having at least one additively functioning warmup enrichment circuit. The apparatus is characterized in that the additive enrichment can be reduced during overrunning. The purpose of this feature is to maintain the cleanest possible exhaust gas even during the warmup phase during overrunning. This is attained, for instance, by means of a logical linkage of an overrunning recognition signal and the output signal of an additively functioning correction circuit for the metering signal.
