New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions. In Europe, where diesel-passenger cars are common, 28,500 deaths annually are attributed to diesel NO x pollution, with 11,500 of those deaths linked to excess emissions.

HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The University of Bremen is the scientific base of the international project known as EMeRGe (Effect of Megacities on the transport and transformation of pollutants on the Regional and Global scales).

Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

A new study led by researchers at the University of Michigan compared regulated and unregulated emissions from both light-duty passenger car (1.7 They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology.
