With the increasingly supervision of emission for heavy duty vehicles, the Europe regulation and the Federal Motor Vehicle Safety Standards require a real road emission test using portable emission measurement system (PEMS). This article aims at the evaluation method for real road emissions of heavy duty vehicles and compares the emission results evaluated from work based method, CO2 mass based method and NTE method. The results show that work based and CO2 mass based average moving window method usually covers more operation conditions of vehicle and engine than NTE method do. The results evaluated from work based method and CO2 mass based method shows proportional relationship of approximately one. The CO2 mass based method shows a more extensive applicability due to not using ECU data from OBD. Besides, depending on different type of tested vehicles, the evaluation results get worse when the window threshold reduced accordingly.
