摘　　要：搭建柴油机排放测试平台,探究某重型柴油机在国六阶段瞬态循环和稳态循环试验中颗粒数目的排放特性。结果表明:无论是瞬态循环还是稳态循环,柴油机颗粒数排放都与其DPF碳载量密切相关。A diesel engine emission test platform is set up to explore the PN(Particle Number)emission characteristics of heavy duty diesel engine under the WHSC and WHTC tests based on ChinaⅥstandard.The results show that the PN emission of both the WHTC and the WHSC are all closely related to the DPF carbon loads.

关 键 词：重型柴油机 国六标准 PN排放特性 瞬态循环 稳态循环
