Study of On-board Exhaust Emissions Measurement Device for Heavy Duty Vehicles (Second Report)

In recent years, measuring exhaust emissions from in-use vehicles on the road using an on-board exhaust gas measurement device (Portable Emission Measurement System (PEMS)) has been studied in Europe and the United States to confirm the correct operation of exhaust emission control systems under actual vehicle operations. Two emissions evaluation methodologies are proposed, the NTE control area method from the United States, and the Average window method from European Commission. In this report both methodologies are compared under actual Japanese vehicle operation, using several heavy trucks meeting recent Japanese emission regulations. The results indicated that the Average window method is better than the NTE control area method for Japanese vehicle driving conditions.
