N2 - Ceramic porous bodies for the diesel particulate filter are studied. There are two types of pores: macro- and meso-pores. The macro-pores, which are continuous, offer the fluent flow of the exhaust gas through the body. The meso-pores, that are formed on the surface of the continuous pores, capture the soots. The main ceramic body is mullite, and meso-pores material is LaFeO 3 that can lower soot combustion temperature. The LaFeO3 powders showed carbon ignition temperature as low as 501-530°C, which implied the decrease of the soot ignition temperature by 120-150°C. It has been shown that the case of 30 degreed continuous macro-pore has a pressure drop of 0.1 atm for 56 mm length filter.
