不同排放阶段公交车燃用生物柴油的排放特性
|
摘要
在底盘测功机上应用日本HORIBA公司的全流气体分析仪对不同排放阶段的公交车分别燃用国Ⅴ、京Ⅵ和掺混体积比为5%的生物柴油混合燃料的排放特性进行研究。研究结果表明,不同排放阶段的公交车在燃用掺混体积比为5%生物柴油时比燃用国Ⅴ或京六柴油时的CO、THC、PM排放因子均有所减小,NO_x排放因子有所增大,但整体升幅不大。燃用掺混体积比为5%的生物柴油的公交车在10 000 km里程耐久后排放因子与耐久前基本无变化。
On the chassis dynamometer, the HORIBA company's full-flow gas analyzer was used to study the emission characteristics of the buses in different emission stages burning national Ⅴ fuel, Beijing Ⅵ fuel and mixed fuels of biodiesel with volume ratios of 5%. The results show that the CO, THC and PM emission factors of the buses burning B5 fuel are smaller compared with those of the National Ⅴ fuel or Beijing Ⅵ fuel. The NO_x emission factor has increased, but the overall increase is not large. The emission factor of the bus that burns B5 fuel has no change after the 10,000 km mileage is exhausted.
