To better estimate soot loadings from the pressure drop of diesel particulate filters (DPFs), a new concept cordierite-based catalyzed DPF has been developed. This new catalyzed DPF features (1) no washcoat layer, which often is the origin of uncertain pressure drop behavior, and (2) a modified substrate composition for improved thermal durability of the catalyst metal without the washcoat layer. Several characteristic were confirmed through engine tests based on this concept.
