Soot and other particles from diesel engines worsen the particulate matter pollution in the air and are harmful to health. [8] New particulate filters can capture from 30% to greater than 95% of the harmful soot. [9] With an optimal diesel particulate filter (DPF), soot emissions may be decreased to 0.001 g/km or less.

Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .

That penalty is more than double the combined total of the administration's 11 previous oil and gas Clean Air Act settlements, officials said. Still, it is dwarfed by Marathon's earnings, which ...
Catalytic converters remove only 20–40% of PM so particulates are cleaned up by a soot trap or diesel particulate filter (DPF). In the U.S., all on-road light, medium, and heavy-duty diesel-powered vehicles built after 1 January 2007, are subject to diesel particulate emission limits, and so are equipped with a 2-way catalytic converter and a ...
California could become the first state to fine big oil companies for making too much money, a reaction to the industry's supersized profits following a summer of record-high gas prices in the ...
Heavy sheens of oil as visible on the surface of the water in Prince William Sound following the Exxon Valdez oil spill. Laws governing oil spills in the United States began in 1851 with the Limitation of Liability Act. This statue, in an attempt to protect the shipping industry, stated that vessel owners were liable for incident-related costs ...
BlueTEC is Mercedes-Benz Group's marketing name for engines equipped with advanced NO x reducing technology for vehicle emissions control in diesel-powered vehicles.The technology in BlueTec vehicles includes a selective catalytic reduction (SCR) system that uses diesel exhaust fluid, and a system of NOx adsorbers the automaker calls DeNO x, which uses an oxidizing catalytic converter and ...
