Speciation of Nitrogen Compounds in the Tailpipe Emissions from a SI Car under Real World Driving Conditions

摘要: The tailpipe exhaust emissions were measured using a EURO4 compliant SI car equipped with on-board measurement systems such as FTIR system for gaseous emission, differential GPS velocity, altitude and position, thermal couples temperatures, MAX fuel meter transient consumption. Various nitrogen species (NO, NO2, NOx, NH3, HCN N2O) at 0.5 Hz. tests designed employed two real world driving cycles/routes representing typical urban road network located in densely populated area main crowded road. Journeys various times of the day conducted to investigate traffic conditions impacts pedestrian lights, congestion, grade turning on emissions, engine efficiency time aligned vehicle moving parameters Nitrogen pollutant emission data consumption enabled micro-analysis correlations between these parameters. average journeys presented, though this paper is focused compounds. Traffic events movements' impact studied. Engine power output has been calculated by specific (VSP). analysis result their relation profile improved understanding compound which will be useful controlling air quality.
