| 摘 要： | 在一台非道路国四高压共轨柴油机上,利用试验台架研究颗粒捕集器(diesel particulate filter,DPF)驻车再生过程中不同排气热管理策略对氧化型催化器(diesel oxidation catalyst,DOC)入口温度及排放的影响。结果表明,合适的再生转速、节气门关闭角度及喷油参数对提升DOC入口温度、降低DOC入口未燃HC效果显著。研究结果可以对柴油机DPF驻车再生排气热管理策略的制定和优化提供指导。

| Abstract: | The influence on the diesel oxidation catalyst(DOC)inlet temperature and DOC inlet HC emission of different heating up strategy on the procedure of diesel particulate filter parking regeneration are investigated on a non-road high pressure common rail diesel engine which meets CHINA 4.The results show that proper parameters of regeneration speed,intake throttle valve opening and injection strategy,have significant effects on rising DOC inlet temperature and reducing DOC inlet HC emission.The result provide guidance for the development and optimization of heating up strategy on the procedure of diesel particulate filter parking regeneration. |
