Abstract

A fuel metering system and method for an internal combustion engine is proposed, having a lambda regulation device and a warm-up enrichment, in which at the onset of regulation the warm-up enrichment is reduced or turned off for the purpose of not having an abnormally high control stroke when transferring to a closed-loop operation and thereby rapidly attaining a stable lambda value.
