| 1 | An evaluation of the emission profile for two-wheelers at a traffic junction显示文摘Two-wheeler vehicles are an important mode of transportation in developing countries.However,the emissions from two-wheeler vehicles are significant.Urban two-wheeler vehicles with gasoline-fueled engines produce NO,and particulate matter emissions that affect urban air quality.During traffic light stops and programmed stops,for instance,pollutants are emitted and are dangerous to human health.In this experimental study,two-wheeler vehicles with different makes,technologies and engine capacities were tested for exhaust emissions including gravimetric and online measurements at different engine speeds and a no load condition at a si mutated traffic junction.Gravimetric measurements were performed by collecting the particulate mass(at two engine speeds:1500 and 2500 rpm) from a diluted engine-out exhaust on quartz filter paper.Next,these collected particulates were used to determine the presence of metals,as well as the benzene soluble organic fraction(BSOF).The total particulate mass,BSOF and trace elements were slightly higher at a higher engine speed(2500 rpm).Online measurements were performed by sampling the engine exhaust(at four engine speeds:1500.2000,2500,and 3000 rpm)and using online instruments to determine the particle number and size distribution,the particle-bound polyaromatic hydrocarbons(PAHs),the gaseous emissions and the smoke opacity.Engines with higher cubic capacity emitted a higher concentration of nano-particles.The particle-bound PAH concentration increased as the engine speed increased,but this concentration was notably low for the highest engine speed tested(3000 rpm).The regulated gaseous emissions increased as the engine speed increased for all vehicles. | Avinash Kumar Agarwal Prakhar Bothra Tarun Gupta Pravesh Chandra Shukla | 2015 | Particuology2015，13，1： | 4 |
| 2 | Emission profiling of diesel and gasoline cars at a city traffic junction显示文摘In congested urban roads,cars must stop at intersections because of city traffic lights.As a result,pedestrians and traffic police personnel are exposed to pollutants emanating from the tailpipe of various vehicles at such city traffic junctions.In this study,various gasoline- and diesel-fueled cars complying with different emission standards were tested for their emissions in simulated city traffic junction conditions.The engine exhaust from these cars was subjected to physicochemical characterization at different engine speeds under no-load conditions.These engine conditions were chosen because the cars idle at different engine speeds at a city traffic junction.Gravimetric and real-time measurements were performed for the tailpipe exhaust sampled from these vehicles.Exhaust particles were collected on 47 mm diameter quartz filter papers and subjected to gravimetric analysis for determining the total particulate mass(TPM)and trace metals while the engines were operated at two different engine idling speeds,1500 rpm(representing low idling) and 2500 rpm(representing high idling).At similar engine operating conditions,TPM and trace metals were lower for the exhaust from gasoline engines compared to the exhaust from diesel engines.Real-time measurements were performed for particle-bound poly-aromatic hydrocarbons(PAHs),particle number and size distribution,regulated gaseous emissions and smoke opacity of the exhaust at four different engine speeds,1500,2000,2500,and 3000 rpm.Particle-bound PAHs showed a decreasing trend for the vehicles that complied with stricter vehicular emission standards.Higher particle peak number concentrations were observed for diesel exhausts compared to the results for gasoline exhaust.Regulated gaseous emissions were also compared. | Avinash Kumar Agarwal Tarun Gupta Prakhar Bothra Pravesh Chandra Shukla | 2015 | Particuology2015，13，1： | 4 |
