摘要
在工况油耗(排放)试验时需要对转鼓的阻力进行设置,而排放法规中规定的"实际道路阻力法"和"查表法"由于操作性差和精度低而无法满足试验的需求,本文根据转鼓上道路阻力模拟的原理,阐述了转鼓道路阻力设置常用的"标准道路阻力法"和"标准转鼓加载法",并提出在试验中应根据不同的试验目标而选用不同的道路阻力设置方法。
In the fuel consumption (emissions) test, the road resistance needs to be set on the dynamometer. Based on the principles of road load simulation on the dynamometer, the paper summarized the commonly used methods for road load simulation settings and recommended the methods according to different objectives of the test.
