摘要：研究分析重型商用车用发动机中国工况关键特征，并与现阶段重型商用车用发动机采用的标准试验循环（WHSC/WHTC）进行对比，分析差异性，为重型商用车用发动机产品研发、排放与OBD标定适应性放行提供参考。
Abstract: The key characteristics of heavy-duty commercial vehicle engines in China were analyzed and compared with the standard test cycle (WHSC/WHTC) adopted by heavy-duty commercial vehicle engines at present. The differences were analyzed to provide reference for heavy-duty commercial vehicle engine product development, emission and OBD calibration and adaptive release.
