This study investigated emission characteristics of polycyclic
aromatic hydrocarbons (PAHs) and reductions of regulated harmful
matters using Premium diesel fuel (PDF), mixed with a 60 L/min flow
rate of H2/O2 mixture and blended with biodiesel 5% (B5), 10% (B10),
20% (B20), and 30% (B30). The diesel engine was operated at
steady-state condition of 1,600 rpm, with torque and power outputs of
145 Nm and 24.5 kW, respectively.
Measured results show that the emission concentrations of total
PAHs were 22.42, 20.11, 17.28, 13.45, and 13.13 £gg/m3 for B0, B5, B10,
B20, and B30, respectively, with corresponding emission factors of total
PAHs being 1334.53, 1198.82, 986.05, 771.93, and 748.82 £gg/bhp-hr, and
reductions of total PAHs being 10.3, 22.9, 40.0, and 41.4%. The results
indicated that using biodiesel can reduce PAH emissions. However, the
emission factors of carbon monoxide (CO) and total hydrocarbons (THC)
were decreased by adding biodiesel, but those of carbon dioxides (CO2),
nitrogen dioxides (NOx), and particulate matter (PM) were increased.
Annual emissions of total PAHs were estimated to be 140.05, 126.92,
105.21, 81.97, and 79.86 ton/year for B0, B5, B10, B20 and B30,
respectively, decreasing with increasing biodiesel. Also, the
corresponding annual emissions of BaPeq were 5.88, 5.62, 3.50, 3.03, and
2.83 ton/year, respectively.
