Fiber Wound Diesel Particulate Filter Durability Experience with Metal Based Additives 970180

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.
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.
