Use of Diesel Particulate Filters and Cerium-Based Fuel-Borne Catalyst for Low Temperature - Low Load Applications 2001-01-0906

The present paper reports the use of a cerium-based FBC in association with a DPF for delivery applications, with long series of stop and go sequences. Two different field trials totaling at least 10,000 km each were performed using delivery conditions with an average of 100 stop-and-go per day and standard diesel fuel (350ppm of sulfur). The US application was done with a medium-heavy duty engine and the European application with a light duty engine. The efficiency of the DPF was determined by measuring both soot and inorganic product emissions. After the trials, the DPF were dismantled and retained ashes were characterized and their localization in the filter analyzed.
