“…Due to the differences in terms of flow rate (over 14 times more for the PFF), the pressure increase over the full size PFF could not be directly compared with the pressure recorded over the 1 inch diameter DPF. Nevertheless, a limited pressure increase was recorded over the tests, which is in agreement with other studies that recorded small pressure increases during the use of a PFF [14][15][16]. The reduced soot mass loading, associated with lower pressure increase, show the potential of the PFF/DPF combination to reduce the duration and/or frequency of active regenerations, allowing either a loading time a third longer or a shorter regenerative event to oxidize the lower mass of soot accumulated within the DPF.…”
