Abstract
A self-cleaning diesel exhaust particulate filter system is disclosed wherein burn-off of collected particulate matter is accomplished at normal exhaust gas temperatures, the filter system being provided with a catalyst mixture of a co-formed ceria-zirconia composite and, optionally, a base metal oxide, the presence of which allows regeneration of filters at temperatures that are readily achieved in diesel exhaust systems, including operating conditions that are at low load where lower exhaust temperatures exist.
