摘　　要：介绍了美国、欧洲等国家和地区的轻型车尾气排放法规运转循环的发展历程及现状。对轻型汽车在不同运转循环FTP75、NEDC和WLTC(第5.3版)下的排放结果进行了分析,并讨论影响排放结果的因素,研究不同运转循环下轻型汽车的排放特性。In this paper, we introduced the driving cycles for light-duty vehicle used by the United States and Europe etc. And we studied the exhaust emission characteristics by comparing the exhaust emission re-sults of light-duty vehicle in different driving cycle FTP75, NEDC and WLTC （Ver.5.3）. And we also discussed the factors that influence the exhaust emission results.
