Abstract
This article presents nondestructive neutron
computed tomography (nCT) measurements of Diesel
Particulate Filters (DPFs) as a method to measure ash
and soot loading in the filters. Uncatalyzed and
unwashcoated 200cpsi cordierite DPFs exposed to
100% biodiesel (B100) exhaust and conventional ultra
low sulfur 2007 certification diesel (ULSD) exhaust at
one speed-load point (1500rpm, 2.6bar BMEP) are
compared to a brand new (never exposed) filter. Precise
structural information about the substrate as well as an
attempt to quantify soot and ash loading in the channel
of the DPF illustrates the potential strength of the
neutron imaging technique.
