Title
(EN) PARTICULATE FILTER SOOT MANAGEMENT FOR INTERNAL COMBUSTION ENGINES
(FR) GESTION DE SUIE DE FILTRE À PARTICULES POUR MOTEURS À COMBUSTION INTERNE
Abstract
(EN) Methods, systems, and devices for particulate filter soot management for internal combustion engines are described herein. A method for particulate filter soot management for internal combustion engines includes determining a quantity of soot on a particulate filter and adjusting a skip fire firing sequence based at least in part on maintaining the quantity of soot on the particulate filter within a desired soot quantity range.
(FR) L'invention concerne des procédés, des systèmes et des dispositifs de gestion de suie de filtre à particules pour des moteurs à combustion interne. Un procédé de gestion de suie de filtre à particules pour des moteurs à combustion interne comprend la détermination d'une quantité de suie sur un filtre à particules et l'ajustement d'une séquence d'allumage à cycle d'allumage sauté sur la base, au moins en partie, du maintien de la quantité de suie sur le filtre à particules dans une plage de quantité de suie souhaitée.
