Title (EN) ENGINE CONTROL SYSTEM HAVING GRADUAL CYLINDER CUTOUT
(FR) SYSTÈME DE COMMANDE DE MOTEUR AVEC COUPURE PROGRESSIVE DES CYLINDRES
Abstract:
(EN) A control system for an engine having a plurality of combustion chambers is disclosed. The control system may have a plurality of fuel injectors associated with the plurality of combustion chambers, and a controller in communication with each of the plurality of fuel injectors. The controller may be configured to determine a need to inhibit fueling of a subset of the plurality of combustion chambers. The controller may also be configured to selectively regulate the plurality of fuel injectors to inhibit fueling of a fraction of the subset at a time until fueling of all of the subset has been inhibited.
(FR) L'invention porte sur un système de commande pour moteur comportant une pluralité de chambres de combustion. Le système de commande peut comprendre une pluralité d'injecteurs de carburant associés à la pluralité de chambres de combustion, et un dispositif de commande en communication avec chacun de la pluralité d'injecteurs de carburant. Le dispositif de commande peut être configuré de façon à déterminer une nécessité d'inhiber l'alimentation en carburant d'un sous-ensemble de la pluralité de chambres de combustion. Le dispositif de commande peut également être configuré de façon à réguler de manière sélective la pluralité d'injecteurs de carburant afin d'inhiber l'alimentation en carburant d'une fraction du sous-ensemble à un certain moment jusqu'à ce que l'alimentation en carburant ait été inhibée pour tous les sous-ensembles.
