摘要
为推行区域大气污染联合防治并推广使用B5生物柴油,基于重型底盘测功机,采用C-WTVC循环,对比研究满足国Ⅳ、国Ⅴ排放标准的柴油公交车分别燃用国Ⅴ柴油、京Ⅵ柴油和B5生物柴油时的非常规污染物排放特性。结果表明:相比京Ⅵ柴油在采用B5生物柴油后,在不同耐久里程下的所有样车整体上的1,3-C_4H_6排放因子平均降低20.53%;C_6H_6排放因子平均降低7.67%;C_7H_8排放因子平均降低11.22%;HCHO排放因子平均降低14.92%;SO_2排放因子平均降低6.09%。实验证明城市公交车在燃用B5生物柴油后的非常规污染物排放均降低。城市公交车推广使用B5生物柴油可有效净化大气质量,对区域大气污染物减排有着重要意义。
In order to promote the joint prevention and control of regional air pollution and the use of B5 biodiesel,based on a heavy-duty chassis dynamometer,a C-WTVC cycle was used to comparatively study the emission characteristics of the unregulated pollutants from diesel buses,which meet the national IV and national V emission standards,using country V diesel,Beijing VI diesel,and B5 biodiesel,respectively.The results showed that in comparison with Beijing VI diesel,for all the testing buses using B5 diesel under different endurance mileages,the emission factors of 1,3-C4H6,C6H6,C7H8,HCHO,SO2decreased by an average of 20.53%,7.67%,11.22%,14.92%,6.31%,respectively.The test proved that the unregulated pollutants emission from all the urban buses using B5 biodiesel was reduced.Promoting the B5 biodiesel usage could effectively purify the air quality and be of great significance for the regional air pollutants reduction.
