| Abstract(E) | This research aimed to improve PN filtration efficiency and catalytic performance of 4way-GPF without worsening pressure drop. Adding PN filtration layer made of three-way catalyst on substrate improves PN filtration performance and catalyst performance, but the deterioration of pressure drop becomes an issue. In this report, we clarified that designing catalyst density is effective in suppressing the deterioration of pressure drop. Finally, we proposed the design concept for 4way-GPF with higher PN filtration, higher catalytic performance and lower pressure drop. |
