Abstract

Système (42) de détermination d’un modèle de remplissage d’air dans au moins un cylindre d’un moteur à combustion interne à allumage commandé d’un véhicule automobile fonctionnant selon un cycle moteur comprenant une phase d’admission de l’air frais par une soupape d’admission et une phase d’échappement d’un mélange gazeux par une soupape d’échappement, lesdites soupapes étant actionnées par un actionneur correspondant autorisant respectivement un déphasage (VVTAdm) de la phase d’admission et un déphasage (VVTEch) de la phase d’échappement. Le système (42) comprend un module (44) de calcul de la masse d’air frais (Mair) enfermée dans le cylindre (12) à la fermeture (FA) de la phase d’admission en fonction d’une pression (Pcyl) dans le cylindre (12), d’un volume de la chambre de combustion (18) du cylindre, d’une température (Tcyl) et d’un taux (Tx_GBR) de gaz brûlés résiduels présents uniquement dans le cylindre (12), ledit taux (Tx_GBR) étant fonction de la pression (Pcyl) et d’une modélisation de la pression équivalente aux gaz brûlés (P0).
