Summary:

A DPNR (Diesel Particulate-Nox Reduction) system is designed to simultaneously remove PM (Particulate Matter) and NOx from the exhaust of diesel engined vehicles. A DPF (Diesel Particulate Filter) is used in the DPNR system to reduce the PM. The DPF must have high PM filtering efficiency, while at the same time having low back pressure. However, filtering efficiency and back pressure have trade off relations. Therefore, it is necessary to optimize the pore distribution in the walls of the DPF to satisfy both characteristics. This paper will explain that optimized control of pore distribution enables both high PM filtering efficiency and low back pressure
