Measurement of vehicle particulate emissions.
نویسنده
چکیده
A constant volume sampler (CVS) compatible auto exhaust particulate sampling system has been built which samples exhaust isokinetically at constant temperature. This system yields internally consistent results and is capable of frequent and convenient operation.

Solid 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 کاملMethods of characterizing the distribution of exhaust emissions from light-duty, gasoline-powered motor vehicles in the U.S. fleet.
Mobile sources significantly contribute to ambient concentrations of airborne particulate matter (PM). Source apportionment studies for PM10 (PM < or = 10 microm in aerodynamic diameter) and PM2.5 (PM < or = 2.5 microm in aerodynamic diameter) indicate that mobile sources can be responsible for over half of the ambient PM measured in an urban area. Recent source apportionment studies attempted ...
متن کاملTime resolved characterization of diesel particulate emissions. 1. Instruments for particle mass measurements.
The measurement of diesel vehicle exhaust particulate mass is currently accomplished using filter collection methods according to the Code of Federal Regulations (CFR). Such filter methods limit time resolution to a minimum of several minutes, making it impossible to study emissions during transient operating conditions. Extensive testing of five different measurement methods has demonstrated t...
متن کاملOn-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 کاملSnap Code:
This Chapter covers the emissions of airborne particulate matter (PM) from road transport which are due to vehicle tyre and brake wear (SNAP code 070700) and road surface wear (SNAP code 070800). PM emissions from vehicle exhaust are not included. The focus is on primary non-exhaust particles in other words those particles emitted directly as a result of the wear of surfaces and not those resul...
