Authors Abstract
Content
Tighter emission regulations, fuel consumption concern, improved durability requirements, packaging and cost reduction are current drivers for after treatment systems development. As the Diesel Particulate Filter is the main component of diesel exhaust systems, catalytic function integration into the DPF has been widely investigated: it has reached an agreement, that increasing the substrate material’s porosity will thus be a solution in order to accommodate higher washcoat loading, and especially higher washcoat base material (non PGM compounds), with acceptable impact on backpressure. In addition to porosity increase, this development focuses on proposing new substrate structures for accommodating washcoat, and thus offering potential for further catalytic functions integration.
