Real World Vehicle Emissions: A Summary of the Fifth Coordinating Research Council On-Road Vehicle Emissions Workshop.
In April 1999, the Coordinating Research Council sponsored a workshop focusing on our understanding of real-world emissions from motor vehicles. This summary presents the latest information on in-use light- and heavy-duty vehicle tailpipe and evaporative emissions, the effects of fuels on emissions, field programs designed to understand the contribution of mobile sources to emission inventories...
متن کاملOn-road Motor Vehicle Emissions from around the World
In 1993, on-road emissions in Continental Europe showed a pronounced South/North declining gradient for CO, HC and NO fuel specific emissions (gm/kg). Emissions in Hamburg and Rotterdam were comparable to emissions measured in 1993 in the U.S.A. with the same on-road instrument. Contrasts between emissions in the USA, the UK and Sweden demonstrated the importance both of modern catalysts and of...
متن کاملVehicle-Based Road Dust Emissions Measurements
TRAKER is a vehicle-based method for measuring road dust emissions. Particulate matter is sampled in front and behind a vehicles tire and the difference in PM concentration (TRAKER signal) is used to infer the airborne flux of particles from the roadway. Two independent tests indicated that the TRAKER signal increases as the cube of the speed for a given road dust loading. Simultaneous measure...
متن کاملEffect of vehicle characteristics on unpaved road dust emissions
This paper presents PM10 fugitive dust emission factors for a range of vehicles types and examines the influence of vehicle and wake characteristics on the strength of emissions from an unpaved road. Vertical profile measurements of mass concentration of the passing plumes were carried out using a series of 3 instrumented towers. PM10 emission fluxes at each tower were calculated from knowledge...
