Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al.

CMU study finds SOA levels in cities like LA will remain high despite cleaner cars; nonlinear relationship between SOA and NOx

Green Car Congress

The findings of a study by researchers at Carnegie Mellon University, with colleagues at UC Berkeley, suggest that changing atmospheric NO x levels over the next two decades will likely significantly reduce the effectiveness of stricter new gasoline vehicle emissions standards in reducing concentrations of secondary organic aerosol (SOA).

CMU study finds taxes on emissions would result in more rapid electrification by ridesharing companies

Green Car Congress

Researchers at Carnegie Mellon’s College of Engineering have found that with an emissions-based incentive towards electrification, ridesourcing companies such as Uber and Lyft would electrify more and cut their emissions by amounts ranging from 10% in New York to 22% in Los Angeles. Air pollution is a classic case where free markets fail.

Study suggests focusing on cold starts in gasoline cars as target for emissions reduction

Green Car Congress

A new study suggests that focusing on a gasoline-fueled vehicle’s cold start is the best target for future design changes to reduce emissions of criteria pollutants. The main goal of our project was to find out how effective regulations of gasoline vehicle emissions have been at reducing the formation of smog.
