From this initial generation of parameter sets, a set of input files for the simulation engine was generated from the template input files.
Unfortunately, in cars, the heat that is generated from internal combustion engines also causes a release in pollutants from exhaust.
Also, the vehicle exhausts were generated from decade-old engine technologies and fuels, wood smoke was generated from an uncertified stove, and the exposure levels encompassed by this report were higher than widespread environmental concentrations.
NO2 is regarded as a secondary pollutant produced from primary source NO which is being generated from internal combustion engines.
Whole, diluted diesel and gasoline exhausts were generated from engines on test stands and operated on variable-load duty cycles.
For one thing, many Web search engines index only Web pages in HTML format, and many Web pages are generated from databases that search engine spiders can't penetrate.
The diesel exhaust was generated from an idling 1991 Volvo diesel engine (Volvo TD45, 4.5 l, four cylinders, 680 rpm).
Diesel exhaust was generated from 2000 model 5.9-L Cummins engines burning 300 ppm sulfur certification fuel and operated on the federal heavy-duty test cycle (McDonald et al. 2004).
Gasoline exhaust was generated from 1996 model General Motors 4.3-L engines burning fuel blended to 2001 2002 national average specifications for regular unleaded, nonoxygenated fuel and operated on the California Unified Driving Cycle (McDonald et al. 2008).
DEP were generated from a light-duty four-cylinder diesel engine (4JB1 type, Isuzu automobile; Isuzu Motors, Tokyo, Japan) using standard fuel and generously provided by M. Sagai (National Insitute for Environmental Studies, Tokyo, Japan).
In theory they take account of everything from how the power is generated to the type of engine and how full the plane or train usually is.
