HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. The project will be executed as four integrated sub-studies.

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.

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Due to its size, any SCR system will likely need to be housed in the aircraft body, potentially making it most suitable for future hybrid- or turbo-electric aircraft designs.

Everyone solemnly agreed, again, to follow the science, which has shown in exhaustive detail that humanity will suffer from heat, fire, floods, and droughts if the world warms beyond 1.5° In almost all previous projections for climate, tipping events like these were far in the future.
