Experimental research on impact of SCR to diesel buses’ emission
Shenzhen Polytechnic in Shenzhen City, China
The emission experiments of a traditional diesel bus and a SCR diesel bus on a selected expressway in Shenzhen city are carried out with a high-precision mobile emission tester. The experiment data are calculated and the buses’ emission characteristics are analyzed. The study shows that the SCR bus NOX emission is higher than the traditional diesel bus when the buses’ velocity is slow and lower than the traditional one when the velocity is fast. The higher velocity on expressway can help SCR diesel buses increase NOX transfer efficiency and reduce NOX emission because that the tailpipe exhaust temperature is high when the diesel bus runs fast.
