In this study we attempted to improve diesel particulate matter (PM) combustion by the simultaneous application of a fuel-born catalyst and a perovskite catalyst The experiment was simulated by mixing fuel-borne catalyst (FBC)-incorporated PM with perovskite catalyst in a physical manner FBC-incorporated PM was achieved satisfactorily using a self-constructed PM generator Through temperature-programmed oxidation (TPO) the catalyst combination of Fe/Ce FBC and La(0 7)K(0 3)FeO(3) effectively Improved the low-temperature combustion of diesel PM with superior performance to that of the Fe/Ce FBC-Pt/Al(2)O(3) combination (C) 2010 Elsevier B V All rights reserved
