Abstract:

The real driving emissions for vehicles are highly regarded within the automotive industry. The USA, EU and China all developed the real driving emission (RDE) regulation because there are obvious differences between the real driving emission and approval appliance. This paper summarized the type and application of the portable emission measurement system (PEMS) to control the vehicle emission; introduced the CO2 moving average window method and power binning method for light-duty vehicle, the work based windows method and not-to-exceed (NTE) method for heavy-duty diesel truck to reveal the research statues of the real driving emission. Therefore, the authors recommend China government constructing a special regulation of real driving emission measurement to suit the situation of road and transportation characteristics in China.

Key words:  light-duty vehicle, heavy-duty diesel trucks, real driving emission (RDE), portable emission measurement system (PEMS)
