对1台符合京Ⅴ排放标准的轻型多点电喷汽油车进行排放测试，分别按照滑行法和查表法设定其阻力，分析了阻力设定方式对排放测试的影响。使用2名驾驶员对1台符合京Ⅴ排放标准的轻型缸内直喷汽油车进行排放测试，分析了驾驶员对排放测试的影响。结果表明：按照查表法设定阻力时的排放结果高于滑行法，在市郊工况时此特征更为明显；驾驶员操作会对车辆排放结果产生影响，部分污染物的差别达到了10％以上。

For a Beijing-Ⅴ light-duty vehicle with electronically controlled multi-point injection ,the road load was set accord-ing to the coastdown and recommendatory method respectively and the influence of loading method on emission testing was ana-lyzed .The influences of drivers on exhaust emission were analyzed through driving the vehicle by two drivers .The results show that the emission of recommendatory method is higher than that of coastdown method and is more obvious in suburb area . The driver operation has certain influence on the emission result and the difference for some pollutants will be beyond 10% .
