摘　　要：采用气相色谱/质谱联用技术(GC/MS),对兰州市以天然气为燃料的出租车及同型号的93#汽油车的汽车尾气进行采样,对比分析天然气汽车与汽油车尾气中有机物的差异。结果表明,以天然气为燃料的汽车尾气中共检测出3种类型的物质总计18种,其中烯烃类物质9种,烷烃类物质3种,苯类物质6种;以汽油为燃料的汽车尾气中共检测出4种类型的物质共计38种,其中烯烃类物质9种,烷烃类物质3种,苯类物质22种,多环芳烃类物质4种。以天然气为燃料的汽车几乎不含有具有致癌作用的苯类物质和多环芳烃类物质,而以汽油为燃料的汽车尾气中该类物质却含量丰富。This paper studies exhaust fumes of environment friendly dual fuel automobiles.Samples were collected from taxies fueled by natural gas, such as Shanghai Volkswagёn, Citrёn, Beijing Hyundai and from other vehicles powered by 93# gasoline in Lanzhou city.Organic matters of the two groups were analyzed, respectively, with GC/MS.The results show that there are 9 olefine, 3 alkane and 6 benzene in the exhaust fumes of Natural Gas Vehicles（NGV）;and 9 olefine, 3 alkane, 22 benzene and 4 Polycyclic Aromatic Hydrocarbon（PAH） in the exhaust fumes of gasoline vehicles.Obviously, the exhaust fumes from Natural Gas Vehicles（NGV） contain few carcinogenic benzene substances and PAHs, as compared with those in waste gas from petrol-powered cars.
