Abstract

L'invention concerne un procédé de commande d'un injecteur air-essence dans une chambre de combustion d'un moteur, notamment deux-temps, ledit procédé comprenant : - une étape de calcul d'au moins une consigne de commande de l'injection d'essence (TIF, SOF) par ledit injecteur, - une étape de calcul d'au moins une consigne de commande de l'injection d'air (Cons_SOI, Cons_DOI) par ledit injecteur, - une étape de calcul d'au moins une consigne consolidée de commande de l'injection d'air (TI, SOI) par ledit injecteur, Ladite étape de calcul de consigne consolidée étant caractérisée en ce qu'elle comporte - une sous-étape d'estimation d'une pression de compression (E_Pcomp) dans la chambre de combustion, - une sous-étape de calcul de termes correctifs des temps morts (E_Tm) à l'ouverture et/ou à la fermeture dudit injecteur en air, - une sous-étape de calcul de ladite au moins une consigne consolidée de commande de l'injection d'air (SOI, TI) en fonction de ladite au moins une consigne de commande de l'injection d'air (Cons_SOI, Cons_DOI) et des sorties desdites sous-étapes précédentes (E_Tm et E_Pcomp).
