摘要: A manganese-based additive was used in this study to investigate the effects on polycyclic aromatic hydrocarbons (PAHs) emission from a natural-aspirated heavy-duty diesel-powered engine. similar turbocharged engine tested and compared with one for PAH emission. The concentrations of 21 individual PAHs (gas + particle phases) metal element (Mn) particulate exhaust diesel fuel, respectively, were determined. Engine (PAHs Mn) collected over modified JAMA J-13 mode by sampling system. By adding 400 mg/kg Mn-based diesel, reduction fraction mean total-PAH plus phase) 37.2%, while 10 higher molecular weight (HMW) PAHs, 64.5%. These results indicate that can act as catalyst enhancing oxidation process reducing considerable amount In addition, HMW averaged 92.4% magnitude lower than This result revealed has pressure temperature thus makes more complete combustion fuel.
