Abstract:
The metal fleece from a metallic microfiber partial flow diesel particulate filter (P-DPF) and PM in an exhaust after-treatment system consisting of a diesel oxidation catalyst (DOC) and P-DPF was analyzed in this research. The metal fibers that make up the metal fleece was covered by grains on the surface in a lengthwise linear manner. The material of the metal fleece and the metal foil were stainless steel alloys which consist of Fe, Cr, Al, and some c. Particulate matter (PM) trapping from an engine exhaust on the metal fleece was then observed. The metal fleece was also coated with ceria by physical vapor deposition to reduce the PM activation energy. Thermogravimetric analysis was done with model soot and real diesel PM on the metal fleece, without and with the catalyst coating. The catalyst coating reduced the activation energy of the model soot by 17% from 167 kJ/mol to 138 kJ/mol and for the diesel PM by 30% from 128 kJ/mol to 90 kJ/mol. Diesel PM had trace elements from the engine oil which were reduced by the DOC. Overall, the after-treatment system did not leak harmful elements into the PM. The agglomerate and primary particles of the PM increased in size as it travelled down the after-treatment system but with evidence of fragmentation. The nanostructure revealed that there was a decrease of graphitization and the crystallite sizes decreased along the after-treatment system. This was supported by measuring the opacity, temperature, C02, NO, and 02 of the gas in the three stages of the exhaust after-treatment system
