Analysis of C1, C2, and C10 through C33 particle-phase and semi-volatile organic compound emissions from heavy-duty diesel engines

Regulated and unregulated emissions from modern 2010 emissions-compliant heavy-duty on-highway diesel engines

The U.S. Environmental Protection Agency (EPA) established strict regulations for highway diesel engine exhaust emissions of particulate matter (PM) and nitrogen oxides (NOx) to aid in meeting the National Ambient Air Quality Standards. The emission standards were phased in with stringent standards for 2007 model year (MY) heavy-duty engines (HDEs), and even more stringent NOX standards for 201...

Comparative Toxicity of Combined Particle and Semi-Volatile Organic Fractions of Gasoline and Diesel Emissions

Measurement of Emissions from Air Pollution Sources. 2. C1 through C30 Organic Compounds from Medium Duty Diesel Trucks

Gasand particle-phase tailpipe emissions from latemodel medium duty diesel trucks are quantified using a twostage dilution source sampling system. The diesel trucks are driven through the hot-start Federal Test Procedure (FTP) urban driving cycle on a transient chassis dynamometer. Emission rates of 52 gas-phase volatile hydrocarbons, 67 semivolatile and 28 particle-phase organic compounds, and...

volatile organic compound emissions from light-duty vehicles in monterrey, mexico: a tunnel study

a two-week tunnel study was conducted in monterrey, mexico during june 2009 to characterizevolatile organic compound (voc) emissions from the local vehicle fleet and estimate the correspondingemission factors (efs). the loma larga tunnel (llt), a 532 meter-long structure that is mainly used by lightduty gasoline-powered vehicles was used as the experimental set-up. ambient air samples (2-hour a...
