FILTERS FOR ENGINE EXHAUST PARTICULATES

Title:

FILTERS FOR ENGINE EXHAUST PARTICULATES

Document Type and Number:

WIPO Patent Application WO/2004/104540

Kind Code:

A1

Abstract:

The regeneration responses of diesel engine exhaust filters are mapped by conducting multiple regeneration runs under controlled conditions of soot loading, exhaust temperature, exhaust flow rate, exhaust oxygen content and/or other regeneration condition variables to generate a multivariate response surface or filter map that can be used to predict regeneration response under other conditions and aid in the design and active management of the filters to improve filter efficiency and extend filter service life.
