The pore structure of DPF is known to have a significant effect on filtration efficiency,pressure drop,and soot *** is reported that the formation of a nanoparticle porous layer on the surface of the DPF inlet wall promotes soot oxidation[1-3].However,the correlation between pore size in the nanoparticle layer and soot oxidation performance,the effect of the layer in actual use environments,and the oxidation mechanism involved have not yet been *** research discussed in this paper therefore formed SiC nanoparticle porous layers of various pore sizes on the inlet wall surfaces of SiC-DPF(creating what will be termed"NPLDPF"here)using the dip-coating method|4|.The NPL thickness was set at 20μm to help enable uniform coating samples to be *** regard to filter pressure drop without soot loading,results for a bare DPF and a Pt/γ-AlO-eoated DPF(catalyzed DPF:Pt=1 g/L)were virtually *** the NPL-DPF,pressure drop increased as pore size was *** contrast,in the case of pressure drop following soot loading(3 g/L).despite the fact that results for pressure drop for the NPL-DPF were higher than those for the bare DPF,they were lower than those for the catalyzed *** is possible to stop deep-bed filtration by forming a nanoparticle porous layer on the surface of the DPF inlet wall[1.5].With regard to soot oxidation performance,the T80 of an NPL-DPF(NPL pore size=350 nm)was found to be40%lower than that of a bare DPF and identical to that of a catalyzed *** addition,reducing the NPL pore size enhanced soot oxidation performance.X-ray photoelectron spectra(XPS),transmission electron microscopy(TEM),andhydrogen temperature-programmed desorption(H2-TPD)results indicated that the vSiC nanoparticle surface was covered by a 5 am SiO oxide *** was found that these oxidized SiC nanoparticles desorbed oxygen at around 450℃.This desorbed oxygen promoted the oxidation of diesel *** addition,the filtration efficiency of the NPL-DPF wi
