摘　　要：使用一辆满足国Ⅳ标准的轻型汽油车在道路阻力设定方式、车辆预置条件、人员操作等因素发生变化的情况下进行多次试验,分析这些因素的变化对试验结果的影响程度,指出在排放控制水平日益提高的情况下,这些因素的变化会对试验结果造成较大影响,因此,在试验过程中对这些影响因素要严格控制。A vehicle accordant with GB18352.2-2005 Phase IV was used to do some Type I tests under different road load, soak condition and driver. The paper analyses effect on the results as change of the test elements. It is pointed out the change of the test elements will affect greatly the test results when the limits of emission is more and more rigorous. So the effect factors must be controlled strictly during the test.
