A fleet average nonfuel nonexhaust VOC emission factor of 58 ± 39 mg veh –1 km –1 was calculated for the missing source, which is greater than the total of all VOCs emitted from vehicle exhausts and their associated evaporative fuel losses. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. We quantify the effects of these trade-offs in terms of emissions reduction and fuel burn increase using representative engine cycle models provided by a major aero-gas turbine manufacturer.

For a number of the most important pollutants, levels were substantially lower than required by regulations. They were tested on multiple repeats of these cycles, and measurements of more than 300 regulated and unregulated air pollutants were made in accordance with the highest laboratory standards. Background. g/hp-hr in 2010.

This new undertaking will capture detailed information on pollutants from vehicle exhaust using remote-sensing equipment and portable emissions monitoring systems. The new initiatives will award each car model a score based on all of the air pollutants they release during real-world, on-road conditions. Earlier post.).

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.

The chemistry of a fuel impacts the emissions from an engine, with the most obvious example being unburned or partially burned fuel which is a major component of engine exhaust. Engine-out exhaust contains typically 1?3% via the unburned or partially burned fuel which is a major component of engine exhaust. —Hubbard et al.
