摘要：
In this study, gaseous pollutants from three Euro-IV diesel buses equipped with urea selective catalytic reduction (SCR) system were investigated using portable emission measurement system (PEMS) in real world operating conditions. A work-based window method was applied to calculate on-road brake-specific oxides of nitrogen (NOx) emissions for the diesel buses. The emission test results showed that the Brake-Specific NOx (BSNOx) emission was significantly higher than the diesel engine corresponding legislation limit because the urea SCR system was not activated or not at optimal operation state under low exhaust temperature condition when the diesel buses run at low average vehicle speed.
