摘　　要：把ELPI用于重型柴油车车载试验中的PM测量,探索ELPI在车载试验中的可行性。通过一个瞬时工况的颗粒物排放分析,研究重型柴油车辆在实际工况中的颗粒物排放特征。发现ELPI在车载试验中的数据具有较好的重复性,根据颗粒物排放的数量浓度峰值,认为控制1μm以下粒径的颗粒物排放是降低重型车颗粒物排放的研究方向。The feasibility of the application of electrical low pressure impactor （ELPI） to the on-board measurement of the particulate matter （PM） in a heavy duty diesel vehicle is investigated. By analyzing PM emission in transient condition, the PM emission characteristics for a heavy duty diesel vehicle are studied. It is found that the ELPI data in on-board test have good repeatability. And according to the peak value of PM emission concentration, it is indicated that reducing the emission of PM less than 1 μm is the fight direction of research for lowering the PM emission of heavy duty vehicles.
