Abstract

L'invention concerne un procédé et un dispositif d'injection de carburant permettant d'injecter une quantité adéquate de carburant conformément à la quantité d'injection de carburant nécessaire à un moteur. Un courant de bobine est mesuré à un ou plusieurs moments au niveau desquels un moment prédéterminé après le démarrage de l'entraînement du solénoïde d'injection de carburant a été atteint et le moment de l'arrêt de l'entraînement du solénoïde est corrigé aux fins de réglage fondé sur la valeur du courant de bobine mesuré. La correction est effectuée en fonction d'une valeur de correction déterminée en fonction de la valeur du courant de bobine mesuré et de la quantité d'injection carburant nécessaire pour le solénoïde ou d'une valeur de correction sélectionnée parmi des valeurs prédéterminées destinées à diverses combinaisons de valeurs de courant de bobine mesuré et des quantités d'injection de carburant nécessaires, la sélection étant effectuée en fonction de la combinaison de la valeur du courant de bobine mesuré et de la quantité d'injection de carburant nécessaire.
