摘　　要：结合理论分析与试验验证,分析了底盘测功机在标准推荐阻力和实际滑行阻力两种设定方法下对整车油耗、排放等试验结果的影响。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CO2值比利用实际滑行阻力设定时测得的大;Ⅲ型试验时两种设定方法对测试结果没有影响;Ⅵ型试验时,利用实际滑行阻力设定时测得的HC、CO和CO2值比推荐阻力设定下测得的小。Based on theory analysis and a lot of tests,this paper analyzed the effects of standard resistance and actual, coasting resistance of chassis dynamometer on complete vehicle fuel consumption and exhaust emission etc.The test results show that the value of CO~ acquired by using standard resistance are larger than that of using actual coasting resistance in the test of type I;in the test of type Ill,these two methods have no effect on the test results;in the test of type VI ,the values of HC,CO and CO2 acquired by using actual coasting resistance are less than those of using standard resistance.
