Abstract A Diesel Particulate Filter (DPF) is a critical device for diesel engine exhaust products treatment. When using
active-regeneration purification methods, on the one hand, a spatially irregular gas flow can produce relatively
high local temperatures, potentially resulting in damage to the carrier; On the other hand, the internal temperature field can also undergo significant changes contributing to increase this risk. This study explores the gas flow
uniformity in a DPF carrier and the related temperature behavior under drop-to-idle (DTI) condition by means of
bench tests. It is shown that the considered silicon carbide carrier exhibits… More >
