Title (EN) SYSTEMS AND METHODS FOR IN-CYLINDER FUEL DOSING FOR EXHAUST AFTERTREATMENT SYSTEM THERMAL MANAGEMENT
(FR) SYSTÈMES ET PROCÉDÉS DE DOSAGE DE CARBURANT DANS LE CYLINDRE POUR GESTION THERMIQUE DE SYSTÈME DE POST-TRAITEMENT DES GAZ D'ÉCHAPPEMENT
Abstract: front page image
(EN) An apparatus comprises a first circuit and a second circuit. The first circuit is structured to determine that a combustion cylinder is operating in a transition period between an exhaust stroke and an intake stroke of the combustion cylinder. The second circuit is structured to provide an injection command during the transition period to a fuel injector associated with the combustion cylinder, the injection command being to inject fuel into a combustion chamber of the combustion cylinder such that at least a portion of the fuel escapes from the combustion chamber through an exhaust port of the combustion cylinder.
(FR) L'invention concerne un appareil comprenant un premier circuit et un second circuit. Le premier circuit est structuré pour déterminer que le cylindre de combustion fonctionne dans une période de transition entre une course d'échappement et une course d'admission du cylindre de combustion. Le second circuit est structuré pour fournir une commande d'injection pendant la période de transition à un injecteur de carburant associé au cylindre de combustion, la commande d'injection étant destinée à injecter du carburant dans une chambre de combustion du cylindre de combustion de telle sorte qu'au moins une partie du carburant s'échappe de la chambre de combustion à travers un orifice d'échappement du cylindre de combustion.
