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。
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.
