摘要/Abstract

摘要： 在“双碳”背景下，为研究重型混动商用车的碳排放，文章对某混动商用车进行动力参数选型匹配，并建立仿真模型。通过对比中国重型商用车测试循环工况（C-WTVC）和中国货车行驶工况（CHTC-HT）的差异发现，CHTC-HT 工况的最高加速度较高，且低速段占比较大，加速度增加和低速行驶时间延长会导致油耗增大，给企业研发新一代重型混动商用车带来挑战。因此，在仿真工况设置时进行对比分析发现，CHTC-HT 工况的百公里油耗比 C-WTVC 工况高 3.8%，碳排放因子相比 C-WTVC 高约 3.5%。

Abstract: In the context of "double carbon", in order to study the carbon emission of heavy hybrid commercial vehicles, this paper selects and matches the power parameters of a hybrid commercial vehicle and establishes a simulation model. By comparing the difference of China-world transient vehicle cycle (C-WTVC) and China heavy-duty commercial vehicle test cycle-heavy truck (CHTCHT), it is found that the highest acceleration of CHTC-HT condition is higher, and low speed section is larger, acceleration increase and low speed driving time will lead to increased fuel consumption, to the enterprise research and development of a new generation of heavy duty hybrid commercial vehicles. Therefore, through comparative analysis in the simulation condition setting, it is found that the fuel consumption of 100 km of CHTC-HT condition is 3.8% higher than that of C-WTVC, and the carbon emission factor is about 3.5% higher than that of C-WTVC.

Key words: C-WTVC; CHTC; heavy-duty commercial vehicle; hybrid power; carbon emission
