    Abstract: 本研究針對台灣地區之雙模燃料系統液化石油氣車輛使用市售九五無鉛汽油與液化石油氣,其尾氣排放多環芳香煙化合物(PAHs)之排放特性加以探討。車輛測試條件包括FTP-75、HWFET測試兩種方式,並採集其粒狀物相與氣相之PAHs,經萃取、淨化及濃縮後,以氣相層析儀(GC / MS)分析21 種PAHs。
    研究結果顯示,使用LPG車輛引擎之PAHs平均排放濃度,明顯偏高於使用市售95-LFG 之排放濃度;若以油耗係數而言,使用LPG 車輛則低於使用市售95 -LFG之排放係數,其原因為LPG在耗油上表現明顯優於市售95-LFG;當車輛使用LPG時,車輛引擎排放PAHs 濃度的削減上,以LPGDL-l 削減效果達55.9 %最佳。
