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.

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 ...
Early in the 1950s scientists discovered that vehicle emissions were a significant factor that had been causing the air quality to deteriorate. [7] This led to the introduction of vehicle emissions standards in California in 1966, furthermore due to the seriousness of the problem, in 1970 the Clean Air Act was introduced in order to regulate these standards all over the United States.

Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a ...
The ICCT expected the cars to pass, and thought they would be able to use the results to demonstrate to Europeans that it was possible to run diesel cars with cleaner emissions. [ 35 ] [ 90 ] [ 91 ] In early 2013, researchers at WVU CAFEE began testing emissions from the three diesel cars: a Volkswagen Passat , a Volkswagen Jetta , and a BMW X5 ...
