摘　　要：利用PEMS(便携式车载排放测试系统)对选定的汽油在用车使用双怠速法、ASM(加速模拟工况)法、实际道路测试方法进行排放测试。测试结果表明:使用双怠速测试在用车排放时,低怠速排放值并非一定高于高怠速测试值;ASM法5025工况测试结果略大于2540工况测试结果;实际道路测试法HC、CO的排放因子随着汽车的加速而有明显的增加;汽车冷热状况对汽车排放影响较为明显;ASM较双怠速法高怠速工况更能准确反映深圳实际道路排放状况。In this paper, PEMS （Portable emissions measurement system） is used mission by means of two-speed idle conditions, ASM （Acceleration Simulation mode method. The resuhs show that： the emission values of in-use vehicles in idle speed to test gasoline vehicle e- ） and the actual road test are not necessarily higher than in high-idle speed in two-speed idle conditions, the emission values in 5025 mode are slightly larger than in 2540 mode in ASM, HC, CO significantly increase as the car accelerated in on-road test method, whether the vehicle is hot or cold is obviously able to affect the emissions. Compared with high-speed idle of two-speed idle conditions, ASM is more able to reflect the actual vehicle emissions on road of Shenzhen.
