部件参数对重型车CO_(2)排放的影响研究

本文基于整车动力和能耗传递链建立了重型车CO_(2)排放模拟计算模型,研究了关键零部件参数对整车CO_(2)排放的影响程度。以3台重型车(产自我国与欧盟)的4个驾驶循环为研究样本,设计了8种部件参数的模拟计算方案,制定了影响程度表征函数进行评价,并通过实验总结了影响CO_(2)排放测试结果的因素,为相关标准的修订提供参考。

This paper established a simulation calculation model for CO_(2)emission of heavyduty vehicles based on the power transmission chain of vehicle,and investigated the degree of influence of key component parameters on the CO_(2)emission of vehicle.Taking four driving cycles of three heavy-duty vehicles as research samples,the simulation calculation scheme of eight component parameters was designed,the characterization function of the degree of influence was formulated for evaluation,and the factors affecting the CO_(2)emission test results were summarized through experiments,which will provide a reference for the revision of the relevant standards.
