Characterizing ash and substrate properties in sintered metal fiber diesel particulate filters using an advanced diagnostic approach
In order to comply with strict air emissions regulations, applicable diesel engines are required to have an installed after-treatment device. A diesel particulate filter (DPF) is one of these aftertreatment devices, and it is used to capture hazardous particulate matter (PM) from the engine exhaust …
