Diesel particulate filter cleaner is on the carrier (the carrier using DPF streaming of ceramic honeycomb carrier closed, it is the unit of the honeycomb ceramic Kong Yan on both ends of the export and entry overlap block, using porous thin wall structure of filter) coating the encapsulation of rare earth and the noble metal catalyst and verify, and catalysts for oxidation, purification and efficiency of the diesel emission of CO and HC, and for diesel particulate emissions (smoke) in the soluble organic matter (SOF) for effective oxidation reaction.Purification rate of particles can be up to 50% 90%, widely used in buses, trucks, engineering machinery, such as diesel exhaust emission control
