摘　　要：在海拔2 200 m对一台国三排放阶段的装载机同时进行低速Ⅰ挡牵引力和污染物排放测试。在无法从发动机自身获取功率数据流的情况下,利用牵引试验数据反向推导出发动机功率,进而计算出发动机累积功。利用SEMTECH DS+系统测量出污染物排放量,结合累积功,计算出装载机整机在牵引试验过程中的比排放。试验测得装载机最大牵引力的同时,也测取了相应的污染物排放量,为装载机排放研究提供了一种新思路。Low-speed 1st gear drawbar pull and contaminant emissions are simultaneously tested on a loader of the Phase 3 national emission standard at an altitude of 2200m.In the absence of obtaining the power data stream from the engine itself,the drawbar test data is used to reversely derive the engine power and then calculate the cumulative work of the engine.The SEMTECH DS+system is used to measure contaminant emissions,and in conjunction with the cumulative work,the specific emissions of the entire loader during the drawbar test are calculated.At the same time as measuring the maximum drawbar pull of the loader in the test,corresponding contaminant emissions are measured,which provides a new idea for the study of loader emissions.
