Abstract

Procédé de correction de l'enrichissement d'un mélange carburant/ait dans une phase de chauffage d'un moteur à combustion interne en fonction d'au moins une grandeur de base du moteur.Dans une phase post-démarrage (ΔtN) à la suite d'une phase de démarrage (ΔtS) et avant le début (tλ) d'une régulation lambda, on adapte l'enrichissement sur la base d'un contrôle grossier en comparant la grandeur de base saisie actuellement et une grandeur de base saisie précédemment et on poursuit l'adaptation en améliorant la grandeur de base.
