Diesel particulate matter (PM) produced from Ultra Low Sulfur Diesel (ULSD), Soy-derived
B20 and Animal fat-derived B20 was collected at two engine operating conditions.
Gravimetric analysis showed the PM emissions to depend on both fuel and engine operating
condition. B20 fuels exhibited higher PM emissions at low load conditions, but lower PM
emissions under high load conditions. The differences between the operating conditions
were less significant for B20 fuels than for ULSD. Elemental Carbon analysis revealed the
B20 PM to contain greater proportions of organic carbon, which may improve diesel
particulate filter (DPF) regeneration. Finally, TEM images showed considerable differences
between ULSD and B20 soot at low engine loads. The B20 soot displayed a more disordered
arrangement of graphene layers. At higher loads, the differences are subtle, but the B20 PM still
displayed a more amorphous structure. There was little difference between the Soy and
Animal fat-derived B20 soot.
