Title (EN) CONTROL OF ENGINE TORQUE DURING AN ACCELERATION PHASE FOLLOWING A DECELERATION PHASE
(FR) CONTROLE DU COUPLE MOTEUR LORS D ' UNE PHASE D ' ACCELERATION SUITE A UNE PHASE DE DECELERATION
Abstract: front page image
(EN)A method for controlling an engine after a deceleration phase (t1) during which fresh air is recirculated into the cylinders, the method being characterized in that during a torque resumption phase (t>t1) immediately following this deceleration phase (t1), the amount of fuel injected into the cylinders is increased as a function of the amount of fresh air recirculated during the deceleration phase. Consequently, the engine torque progresses more quickly (92 > 90).
(FR)Procédé de contrôle moteur après une phase de décélération (tt1) de reprise de couple immédiatement consécutive à cette phase de décélération (t1), la quantité de carburant injecté dans les cylindres est augmentée en fonction de la quantité d'air frais recirculé pendant la phase de décélération. Ainsi le couple moteur progresse plus rapidement (92 > 90).
