| Abstract: | Two independent measurement devices for vehicle gaseous pollutants and particulate matter (PM) are integrated to form an integrated portable emission measurement system (IPEMS), which can measure the emission concentration of various pollutants ( HC, CO, NOx and PM) real time and calculate the transient emission mass of heavy-duty vehicles. The results of real vehicle emission measurement and comparison test in laboratory show that the built system IPEMS has good measurement reproducibility, and there is strong correlativity between the emission measured results by IPENMS and that by laboratory system, meeting the technical requirements of accurate measurement and evaluation of emissions from heavy-duty vehicles at real road conditions. |
