| Abstract:On-road emission characteristics of heavy-duty diesel vehicle were measured using a portable emission measurement system (PEMS) to test whether it is compliant with China Ⅴ emission PEMS standard. The NOx emissions characteristics before and after the use of SSCR after-treatment system show that compared with the original NOx emissions, the vehicle with a SSCR system can reduce NOx by 61.3% on urban roads, and 85.3% on expressways. The test results indicate that the China Ⅴ heavy-duty diesel vehicle with a SSCR system is compliant with PEMS standard when it is running on roads. |
