Title
(EN) SYSTEM AND METHOD TO MAINTAIN HOT AFTERTREATMENT AT ENGINE IDLE
(FR) SYSTÈME ET PROCÉDÉ POUR MAINTENIR UN POST-TRAITEMENT À CHAUD AU RALENTI D'UN MOTEUR
Abstract
(EN)
A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a transmission, an aftertreatment system, an accessory device and a controller. The aftertreatment system reduces emissions in an exhaust of the internal combustion engine. The accessory device is configured to provide power. The controller operates in an aftertreatment heat-up mode such that the aftertreatment system is heated up to an elevated temperature and emissions are thereby reduced based on the elevated temperature. The controller is configured to heat up the aftertreatment system to reach between one (1) and two (2) kilowatt hours (kWh) of enthalpy before two minutes at engine startup by (i) operating the internal combustion engine in cylinder deactivation mode (CDA); (ii) operating the internal combustion engine at an elevated idle speed; and (ill) operating the accessory device at a threshold power.
(FR)
Selon l'invention, un système de transmission couplé sélectivement à un vilebrequin de moteur d'un moteur à combustion interne monté sur un véhicule comprend une transmission, un système de post-traitement, un dispositif accessoire et un moyen de commande. Le système de post-traitement réduit les émissions dans un échappement du moteur à combustion interne. Le dispositif accessoire est configuré pour fournir une puissance. Le moyen de commande fonctionne dans un mode de réchauffage de post-traitement, de sorte que le système de post-traitement est réchauffé jusqu'à une température élevée et que des émissions sont ainsi réduites sur la base de la température élevée. Le moyen de commande est configuré pour réchauffer le système de post-traitement afin d'atteindre entre un (1) et deux (2) kilowattheures (kWh) d'enthalpie en moins de deux minutes au démarrage du moteur (i) en faisant fonctionner le moteur à combustion interne en mode de désactivation de cylindre (CDA); (ii) en faisant fonctionner le moteur à combustion interne à une vitesse de ralenti accéléré; et (iii) en faisant fonctionner le dispositif accessoire à une puissance seuil.
