摘　　要：NEDC循环中,基于试验验证测量轻型车I型排放试验结果时,底盘测功机不同阻力设定的方法对排放、油耗结果有影响。在查表法和滑行法两种不同的阻力设定下,对测功机的阻力设定方法进行理论分析,进行油耗的影响进行了试验研究。试验结果表明,Ⅰ型试验时,利用标准推荐阻力对底盘测功机进行设定时测得的综合油耗比利用实际滑行阻力设定时测得的高。In the NEDC cycle,the results of the different resistance setting of the chassis dynamometer have an impact on the emission and fuel consumption results when the test results are tested to measure the type I emission test results of light vehicles.Under two different resistance setting,the method of resistance setting of dynamometer is analyzed and the influence of oil consumption is studied.The test results show that in type I test,the comprehensive oil consumption measured by the standard recommended resistance to the chassis dynamometer is higher than that of the actual sliding resistance setting.
