In-Depth Information
It was seen that particle collected on the
filter substrates was quite low for aged
particulates for B20 at 75 and 100 % engine loads, respectively.
PAHs were very high for both primary and secondary particulates in case of
diesel. PAHs were extremely high in secondary emissions for both the fuels.
B20 particulates were loaded to a higher degree with PAHs.
For both the fuels, higher toxicity for secondary particles was found as com-
pared to primary particles. B20 particles showed overall
lower toxicity as
compared to the mineral diesel.
