摘    要:通过车载实验,怠速法检测、简易工况法检测数据评价分析等方法,研究了重庆市在用CNG车辆排放情况,比较了CNG车与同类型汽油、柴油车尾气污染物排放情况。研究发现,目前CNG在用车并非绝对的环保汽车,其中在NOx的排放上,CNG车排放高于同类型汽油、柴油车0.03—14倍;在CO、THC的排放上,不同测试工况下CNG汽车表...

关 键 词:CNG汽车  车载实验  排放

Abstract:In this paper, the emission of CNG fuel used in vehicles in Chongqing was investigated by on-road test, idle conditions test and simple driving mode conditions test. The emission compared between CNG vehicles with the same type gasoline fuel vehicles or diesel fuel vehicles. The results showed that current on-road CNG fuel vehicles were not absolute environmentally-friendly as imagine, NOx emission was 0.03 - 14 times higher than the same type gasoline fuel vehicles or diesel fuel vehicles, CO and THC emissions were higher or lower than the same type gasoline fuel vehicles or diesel fuel vehicles in different test conditions.
Keywords:CNG fuel vehicle  on-road test  emission
