Abstract
Emission experiment in a turbocharged direct-injection diesel engine fuelled with biodiesel, diesel and B20 was carried out. The particle-phase and gas-phase polycyclic aromatic hydrocarbons (PAHs) emissions were collected by fiberglass filter and 'polyurethane foam (PUF) + XAD-2' respectively and analyzed by GC-MS. The results showed that particle-phase, gas-phase and total PAHs emissions of biodiesel decreased at most engine operation conditions and the mean concentrations were lower than those of diesel. Proportions of two-ring PAHs emissions of three tested fuels have 50 percent. Biodiesel can reduce the proportions of PAHs except for two-ring PAHs. Toxic equivalence of PAHs emissions of biodiesel was decreased greatly compared with that of diesel. Utilization biodiesel can reduce the hazard emissions of PAHs.
