Abstract
Official abstract text for this publication.
A diesel particulate filter (“DPF”) system that suppresses clogging of a DPF and enhances convenience including accumulated particulate matter (“PM”) quantity estimator for estimating an accumulated PM quantity in an idle state; and a long low idle forced regeneration unit 5 that if the accumulated PM quantity estimated by the accumulated PM quantity estimation estimator exceeds a predetermined quantity, performs long low idle forced regeneration that automatically performs regeneration of the DPF, and the long low idle forced regeneration unit, when a vehicle starts moving during long low idle forced regeneration, performs automatic regeneration of the diesel particulate filter while the vehicle is moving.
First claim
Opening claim text (preview).
The invention claimed is: 1. A diesel particulate filter system, comprising: a diesel particulate filter provided in an exhaust pipe of a vehicle engine; a sensor for detecting whether the engine is in an idle state; a sensor for detecting whether the vehicle is moving; an accumulated particulate matter quantity estimation device for estimating an accumulated particulate matter quantity during a detection of the idle state of the engine; and a long low idle forced regenera…
