Title:
ディーゼルエンジン排気システムのディーゼル排気微粒子フィルタを保全する方法及び装置
Document Type and Number:
Japanese Patent JP5102873
Kind Code:
B2
Abstract:
A method and apparatus for maintaining a diesel particulate filter (DPF) is provided. A pressure drop across the DPF is measured and an initial estimate of soot loading in the DPF is provided to a recursive filter. Using the recursive filter, the initial estimate of soot loading is updated in view of the measured pressure drop to provide an updated estimate of soot loading in the DPF. Active regeneration of the DPF is triggered when an earliest one of at least one triggering condition occurs, the updated estimate of soot loading reaching a predetermined value being one of the at least one triggering condition.
