This paper is clarifying the exhaust emissions characteristics of in-use DI diesel vehicle in actual running condition. Various measurement instruments were installed in test vehicle (passed 1988 Japanese exhaust emission regulation), and a micro dilution tunnel (MDLT) system was installed in the vehicle. Then, the actual running experiments were carried out for the test route including expressway and local street around Doshisha University. PM was separated into soluble organic fraction (SOF) and insoluble organic fraction (ISOF) with applying a soxhlet extraction technique, and the relation between the running conditions and the PM component was investigated.
