Abstract
The life of DPF would be decided by ash durability because pressure loss of DPF is increased by accumulation of ash that is produced when soot is burnt in the DPF.
We could succeed to increase maximum ash capacity and extend the life of the DPF by an approach from the filter design, making inlet cell volume larger than outlet cell. Furthermore, when the inlet cell is designed octagon, we found that slanted wall blocking the inlet cells is functional worked for soot filtration. As the results, we could improve to manage both transient pressure loss while the soot is collected and the ash durability by the cell shape with (inlet cell/outlet cell) = (octagon/square).
