As a material for a diesel particulate filter, metal foam shows better mechanical and thermal characteristics than ceramic. So the feasibility of metal foam filters were investigated in DPF(diesel particulate filter trap) system in this study. Three proto type DPFs using the Pure Nickel foam filter and Nickel alloy(INCONEL 625) foam were tested. The characteristics of back pressure, PM mass and nano-particle reduction performance were compared with wall flow type filter at the various engine operation conditions. It was confirmed that metal foam filters have a possibility for the application in DPF system.
