DIESEL PARTICULATE FILTER AND EXHAUST GAS PURIFICATION DEVICE |
摘要 |
Provided is a novel DPF which can prevent PM from accumulating on the surface and interior of a filter substrate, and can suppress an increase in back pressure caused by exhaust gas. The DPF has a configuration in which an inorganic porous layer, which includes a metal oxide or a metal composite oxide and is provided with surface irregularities having a thickness of at least 50% of the thickness of the inorganic porous layer, is formed on part or all of the surface of the dividing wall on the side where exhaust gas flows in. |
