The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.

Shanghai to spend $1.63B over next 3 years to target air pollution, especially PM2.5

Green Car Congress

Exhaust from motor vehicles and boats account for 25% of the PM 2.5 , according to the Shanghai Environmental Protection Bureau said yesterday. Their exhaust discharge is 20 to 30 times that of new cars. Shanghai will expand the areas banning these high-polluting vehicles and eliminate 150,000 of them by 2014. measurement.

KCL study finds London air pollution from traffic improving, but continues to exceed limits in many parts of city

Green Car Congress

The study, published as an open-access paper in the journal Environmental Pollution , examined trends in air pollution over a ten-year period spanning 2005 to 2014, using data collected from 65 roads. Overall, there was a decrease in total traffic between 2005 and 2014, mainly explained by the reduction in cars and taxis.

Taxi version of Mercedes-Benz B-Class with natural gas drive coming soon

Green Car Congress

The Mercedes B 200 Natural Gas Drive offers a reduction in CO 2 emissions of more than 16%, markedly cleaner exhaust gases than with gasoline or diesel fuel and fuel costs which are some 50% lower than those for a comparable gasoline-engine model. From 2014 the B 200 Natural Gas Drive will also be available as a taxi version.

Ford introduces second-generation 6.7L Power Stroke V8 Diesel for F-Series Super Duty; Gen 1 hits 500,000 mark

Green Car Congress

The advanced design places the exhaust inside the engine’s V-shape while the air intake is positioned on the outside of the V. This segment-exclusive design naturally improves a variety of attributes: Shorter airflow from the exhaust system to the turbocharger sitting between the engine’s cylinder banks improves turbo responsiveness.

Mazda introduces HAZUMI concept along with new 1.5-liter SKYACTIV-D diesel

Green Car Congress

The result is cleaner combustion with low NO x and soot emissions. Also due to the low compression ratio, the SKYACTIV-D diesel engine also burns cleaner, discharging far fewer nitrous oxides while producing virtually no soot. Misfiring is avoided by adopting a variable valve lift (VVL) system for the exhaust valves.
