Fiber Wound Diesel Particulate Filter Durability Experience with Metal Based Additives

Abstract

<div class="htmlview paragraph">Performance and durability tests were conducted on ceramic fiber-wound diesel particulate filters in the exhaust stream of both laboratory and in-service diesel engines. Metal-based additives were used to facilitate filter regeneration.</div> <div class="htmlview paragraph">Copper, iron and cerium additives were evaluated in laboratory tests for their effect on particulate filter performance and durability during tests totaling more than 3500 hours. Field data obtained on in-service vehicles validated and supplemented laboratory results. Effects of the additive on engine performance and durability are also presented.</div>
