Abstract

L’invention concerne un procédé de correction d’une richesse de carburant alimentant un moteur (1) thermique lors d’un démarrage à froid à une température inférieure à une température de fonctionnement d’une sonde de richesse (6). Une quantité de carburant injectée dans le moteur (1) lors du démarrage en vigueur est corrigée selon une quantité corrigée mémorisée lors d’un précédent démarrage permettant d’atteindre une consigne de richesse, le précédent démarrage ayant au moins une caractéristique de température prise parmi les températures initiales de température de fluide de refroidissement, de température d’air admis, de température d’huile de lubrification et de température d’air extérieur de moins de 10% de la caractéristique de température du démarrage en vigueur, une condition limitative du procédé étant une durée d’arrêt du moteur (1) avant le démarrage précédent et avant le démarrage en vigueur suffisante pour une macération, les températures initiales différant de moins de 20%.
