Title
(EN) DUAL FUEL ENGINE AND METHOD FOR CYLINDER BANK CUTOUT DURING LIGHT LOAD CONDITIONS
(FR) MOTEUR À CARBURANT DOUBLE ET PROCÉDÉ DE COUPE-RANGÉE DE CYLINDRES PENDANT DES CONDITIONS DE CHARGE LÉGÈRE
Abstract
(EN)
The present disclosure relates to dual fuel internal combustion engines with multiple cylinder banks and/or cylinder subsets, and exhaust aftertreatment systems associated therewith. Systems and methods are disclosed that relate to engine operations involving fuelling control for fuel cutout of one or more of the cylinder banks and/or cylinder subsets in response to a fuel cutout event to increase gaseous fuel substitution on the other cylinder banks and/or cylinder subsets to satisfy the torque request and thermal management conditions of the aftertreatment system.
(FR)
La présente invention concerne des moteurs à combustion interne à carburant double avec de multiples rangées de cylindres et/ou sous-ensembles de cylindres, et des systèmes de post-traitement d'échappement associés. L'invention concerne des systèmes et des procédés qui se rapportent à des opérations de moteur impliquant une commande d'alimentation en carburant de coupe-carburant d'une ou de plusieurs rangées de cylindres et/ou sous-ensembles de cylindres en réponse à un événement de coupe-carburant pour augmenter une substitution de carburant gazeux sur les autres rangées de cylindres et/ou sous-ensembles de cylindre pour satisfaire les conditions de demande de couple et de gestion thermique du système de post-traitement.
