On-road measurement of "ne particle and nitrogen oxide emissions from light- and heavy-duty motor vehicles
An updated assessment of "ne particle emissions from lightand heavy-duty vehicles is needed due to recent changes to the composition of gasoline and diesel fuel, more stringent emission standards applying to new vehicles sold in the 1990s, and the adoption of a new ambient air quality standard for "ne particulate matter (PM 2.5 ) in the United States. This paper reports the measurement of emiss...
متن کاملSolid Particle Number Emission Factors of Euro VI Heavy-Duty Vehicles on the Road and in the Laboratory
Particulate matter (PM), and in particular ultrafine particles, have a negative impact on human health. The contribution of vehicle PM emissions to air pollution is typically quantified with emission inventories, which need vehicle emission factors as input. Heavy-duty vehicles, although they represent a small percentage of the vehicle population in nearly every major country, contribute the ma...
متن کاملVehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil.
In the metropolitan area of São Paulo, Brazil, ozone and particulate matter (PM) are the air pollutants that pose the greatest threat to air quality, since the PM and the ozone precursors (nitrogen oxides and volatile organic compounds) are the main source of air pollution from vehicular emissions. Vehicular emissions can be measured inside road tunnels, and those measurements can provide infor...
متن کاملQuantifying on-road emissions from gasoline-powered motor vehicles: accounting for the presence of medium- and heavy-duty diesel trucks.
Vehicle emissions of nitrogen oxides (NOx), carbon monoxide (CO), fine particulate matter (PM2.5), organic aerosol (OA), and black carbon (BC) were measured at the Caldecott tunnel in the San Francisco Bay Area. Measurements were made in bore 2 of the tunnel, where light-duty (LD) vehicles accounted for >99% of total traffic and heavy-duty trucks were not allowed. Prior emission studies conduct...
متن کاملToxicological Assessment of Particulate Emissions from the Exhaust of Old and New Model Heavy- and Light-Duty Vehicles
The primary objective of this project is to develop an improved understanding of the factors affecting the toxicology of particulate exhaust emissions. Diesel particulate matter is a known carcinogen, and particulate exhaust emissions from both light-duty and heavy-duty vehicles are toxic. Particulate matter emissions from three light-duty vehicles in five different configurations [a Honda Acco...
