摘　　要：无铅汽油的广泛使用,使得汽油机苯及苯系物等有害物质的排放量有所增加。为了解三元催化器对汽油燃烧过程中苯及苯系物生成的影响,在HL495IQ电喷汽油机上进行了一系列试验。通过活性炭采样管收集尾气中的排放物,经气相色谱仪分析得到苯及苯系物的排放量,并对其生成规律进行了分析。Using unleaded gasoline widely in vehicles makes the emissions of harmful benzene and benzene series increase.In order to know the influence of three-way catalytic converter on emissions of benzene from gasoline combustion process,a series of tests are carried out on a HL495IQ electronic fuel injection gasoline engine.The exhaust emissions are collected by an activated carbon sampling pipe.The emissions of benzene and benzene series are measured by a gas phase chromatography.The formatting rules of benzenes are analyzed.
