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.

ORNL Researchers Find Thermochemical Exhaust Heat Recuperation In Internal Combustion Engines Could Provide Substantial Boosts in Second-Law Efficiency

Green Car Congress

When reforming is not used, the fuel and exhaust pass through CV2 unchanged. The basic concept of TCR involves using exhaust heat to promote on-board reforming of hydrocarbon fuels into syngas (a mixture of carbon monoxide and hydrogen). The upper inner control volume (CV1) contains the combustion chamber and piston. Click to enlarge.
