Fig. 6 Integrated particulate matter (PM) mass and surface area concentrations versus engine load
for primary and secondary exhaust fuelled with diesel and B20 (adapted from Agarwal et al.
2013
)
load, the mode of number-size distribution (Fig.
2
) shifts toward right and the area
under the curve is maximum, which results in the maximum particle surface area for
primary diesel emissions (Fig.
6
). At all engine loads, the surface area distribution in
primary emissions from diesel is an order of magnitude higher than B20.
