MODEL ANALYSIS FOR EMISSIONS OF LIGHT-DUTY GASOLINE VEHICLES IN A TYPICAL CITY

  • 摘要: 为建立典型城市机动车驾驶模式并量化其尾气排放,研究选取成都市内26辆满足国Ⅴ排放标准(GB 18352.5-2013《轻型汽车污染物排放限值及测量方法(中国第五阶段)》)的轻型汽油车,利用便携式尾气测量系统测量其现实条件下的行驶工况及尾气排放,并根据实际情况结合分类回归树方法构建本地化的驾驶模式并分析各模式的尾气排放。结果表明:划分的加速、减速、匀速、怠速、停走5种驾驶模式,可以反映车辆行驶过程中尾气排放和油耗特征。不同驾驶模式间的尾气排放有显著差异。通常情况下,以加速最大,其次为匀速、停走、减速,以怠速最小。根据污染物不同,不同模式间的尾气排放差异可达到12倍。此外,现实条件下车辆尾气超标排放的情况严重,且存在间歇性高排放的现象。这说明构建典型城市驾驶模式并分析其模式排放特征有助于估算小尺度的机动车尾气排放清单,并为交通管理和尾气排放控制提供数据参考。
