柴油车排放颗粒物污染对环境和人体健康有重要危害，一直是研究的热点。本文对发动机运行工况、环境温度和燃油品质等因素对柴油车颗粒物排放的影响，柴油车颗粒物排放的测试采样方法，质量、形貌以及粒径分布等物理特征，以及元素、EC/OC、无机离子和有机组分等化学特征的研究进展进行了综述，对中国已有研究存在的问题进行了归纳，并对未来相关研究进行了展望。目前，中国柴油车颗粒物源成分谱、采样分析方法，以及颗粒物组分的排放特征都需要进一步深入研究。
Particulate Matter (PM) emission from diesel vehicle has important harm on environment and human health, which has been the focus of the researchers. The studies about the impacts of the important factors including engine driving cycle, ambient temperature and fuel quality on the PM emission from diesel vehicle, the sampling and testing method, physical characteristics of particles from diesel vehicle mainly related to the quality, physical form and particle size distribution, and chemical characteristics such as elements, EC/OC, inorganic ions and organic components of diesel particles were reviewed. Currently, composition spectrum of particulate matter from diesel need to be completed and update, sampling and analysis methods to be more accurately, the emission characteristics of particulate matter components need to be more studied.
