An Overview of Portable Emissions Measurement System Technologies and Relevant Research

The emerging and development of portable emissions measurement system(PEMS) technologies present a new approach for the research of vehicle emissions.The new approach has the advantages that traditional testing technologies do not have such as convenience,real-time nature,and the capability to collect large amounts of data.At present,the research areas by using portable emissions measurement systems include developing emission models based-one real-time data,analyzing microscopic vehicle emission characteristics,and temporal-spatial distribution of emissions,etc.This paper presents a brief introduction to the status of the above research fields,which may provide some useful references to the research and development related to portable emissions measurement systems technologies in China.
