Ash Accumulation and Transport in Diesel Particulate Filters (First Report)

-Quantification of Ash Accumulation Density Distribution by X-ray CT Imaging-

Abstract

In this study, the ash accumulation distribution and density was investigated by observing the ash accumulation site in the DPF using the X-ray CT scanner based on the characteristic that the transmittance of X-rays is proportional to the density of the substance. Quantitative analytical method without DPF destruction was established and the correlation between the ash accumulating condition and ash accumulation site in DPF is discussed in this report from the results of the quantitative analysis.
