| 摘 要： | 采用便携式排放测试系统(Portable Emissions Measurement System,PEMS)测试了4种不同车型的气态污染物(HC、CO、NOx)排放因子。结果表明:微型汽车实测结果,CO排放因子是排放限值和《指南》的5~7.52倍和2.57~11.06倍,NOX排放因子是排放限值和《指南》的32.93~60倍和49.4~64.1倍,THC排放因子是排放限值和《指南》的4.9~9.8倍和4.01~30.6倍;轻型汽车实测结果,CO排放因子是排放限值和《指南》的4.8~18倍和1.5~34倍,NO X排放因子是排放限值和《指南》的1.67~19倍和2~39倍,THC排放因子是排放限值和《指南》的13倍和19倍;重型汽车实测结果,CO排放因子是排放限值和《指南》的12.65~12.89倍和5.16~7.39倍,NOX排放因子是排放限值和《指南》的3.14倍和1.4倍,THC排放因子低于排放限值;低速货车实测结果,CO排放因子是排放限值和《指南》的2倍左右,NOX和THC排放因子低于排放限值。该研究结果可为拉萨市机动车污染物排放控制及机动车管理提供相关依据。

| Abstract: | The Portable Emissions Measurement System(PEMS)is used to test the emission factors of gaseous contaminant(THC,CO and NOx)in 4 different car models.The results showed that 1)According to result of the actual measurement for Midget Car,the emission factor of the CO is 5 to 7.52 times the release limits and is 2.57 to 11.06 times Guide.For NOx,test result is 32.93~60 times the release limits and 2.57 to 11.06 times Guide.For THC,it is 4.9 to 9.8 times release limits and 4.0 to 30.06 times Guide.For Light-duty Vehicle,the emission factor of CO is 4.8 to 18 times the release limits and 1.5~34 times Guide.For NOx,the emission factor is 1.67 times the release limits and 5.16 to 7.39 times Guide.For THC,the emission factor is 13 times the release limits and 19 times Guide.For Heavy Truck,the emission factor of CO is 12.65 to12.89 times the release limits and 5.16~7.39 times Guide.For NOx,the emission factor is 3.14 times the release limits and 1.4 times Guide.For THC,the emission factor is less than the release limits.For Low-speed Truck,the emission factor is 2 times both release limits and Guide.For NOxand THC,both is less than the release limits.The research result can provide relevant basis for controlling the motor vehicle emission in Lhasa,China. |
