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.

Environment Canada study finds vehicle exhaust a significant source of isocyanic acid; suggests consideration of new emission standard

Green Car Congress

Researchers at Environment Canada have found that vehicle exhaust is a significant source of isocyanic acid (HNCO), a toxic gaseous acid that is a product of various forms of combustion and a potential health concern. Automobile exhaust is also a known source of inorganic acids such as nitric (HNO 3 ) and nitrous (HONO) acids.

Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

The research by the University of Edinburgh measured the impact of diesel exhaust fumes on healthy volunteers at levels that would be found in heavily polluted cities. When assessed in the clinic, we showed that the vascular dysfunction associated with diesel exhaust inhalation is prevented by particle filtration.

Bosch increases commercial vehicle diesel injection pressure to 2,500 bar

Green Car Congress

As it outlined in 2010, Bosch has increased the maximum injection pressure of its CRSN3-25 injection system for medium- and heavy-duty commercial vehicles to 2,500 bar. This increases flexibility in terms of engine design, promotes lower exhaust and fuel consumption levels, and results in even quieter operation. Its sales came to €30.4

TravelCenters of America LLC planning to install 50 on-island DEF dispensers in 2011

Green Car Congress

TravelCenters of America LLC confirmed its on-island DEF (diesel exhaust fluid for use with selective catalytic reduction exhaust aftertreatment systems) dispenser roll-out. TA expects to install about 50 on-island DEF dispensers at locations across the country in 2011. DEF is a nontoxic solution of 67.5% purified water and 32.5%
