Title
(EN) SYSTEM AND METHOD FOR DETECTING DIESEL PARTICULATE FILTER CONDITIONS BASED ON THERMAL RESPONSE THEREOF
(FR) SYSTÈME ET MÉTHODE DE DÉTECTION DE L'ÉTAT D'UN FILTRE À PARTICULES DIESEL BASÉE SUR SA RÉPONSE THERMIQUE
Abstract
(EN)
Systems and methods to determine conditions of a diesel particulate filter (DPF) based on correlation between predicted and actual thermal data of the fluid exiting a DPF are provided. Soot loading, ash loading, and/or DPF damage may be detected, and DPF operational models may be calibrated in accordance with such systems and methods. Further, initiation of regeneration may also be effected in accordance with such systems and methods.
(FR)
L'invention porte sur des systèmes et méthodes de détection de l'état d'un filtre à particules diesel (DPF) basés sur la corrélation entre les données prédites et les données actuelles du fluide sortant du filtre. On peut ainsi détecter la charge en suie et en cendres et/ou les dommages subis par le filtre. Lesdits systèmes et méthodes permettent de plus d'étalonner des modèles opérationnels de filtres, et de déclencher la régénération de filtres.
