This paper was focused on the particulate matter (PM) behaviors from DI diesel engine and vehicle. PM from diesel engine is considered one of the sources on the air pollution and respiratory diseases. In this paper, particle behaviors were analyzed by DMS500 (Differential Mobility Spectrometer). PM was measured with commonly used operating conditions and different three sampling point on the upstream and downstream of DOC (Diesel Oxidation Catalyst) and DPF (Diesel Particulate Filter). In the vehicle test, NEDC mode (New European Driving Cycle) was applied and PM was directly measured on the tail-pipe. DOC decreases the nano-particle number, however particle mass keep the nearly same level. DPF has high filtration efficiency.
