SwRI engineers help develop post-refinery diesel treatment that overcomes soot/NOx tradeoff for cleaner burning fuel

Green Car Congress

Southwest Research Institute (SwRI) is helping a client develop a simple post-refinery treatment process that reduces exhaust emissions from diesel engines by overcoming the soot/nitrogen oxides (NO x ) reduction trade-off that has plagued engine researchers for decades.

ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture.

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

Green Car Congress

SOA production depends on both precursor concentrations (e.g., intermediate volatility organic compound (IVOC) emissions from vehicles) and atmospheric chemistry (SOA yields due to the photo-oxidation of exhaust). Robinson (2017) “Reducing secondary organic aerosol formation from gasoline vehicle exhaust” PNAS doi: 10.1073/pnas.1620911114.

Tesla Semi real-world sightings show that a cleaner, quieter future is possible for the trucking sector

Teslarati

The Tesla Semi may still be in its initial production, but the units that have been delivered to PepsiCo are already making a strong statement. If anything, they emphasize the idea that it is possible to adopt a cleaner, quieter alternative to conventional trucking solutions featuring large, noisy, Class 8 diesel-powered semitrailers today.

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.

Corning expands light-duty vehicle exhaust filter capacity in Germany

Green Car Congress

The Corning DuraTrap AT HP filter, the latest advancement in Corning’s DuraTrap AT family of diesel filter products, is a compact aluminum titanate solution that meets those needs. These engines produce a high number of fine particulates that pollute the air.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. Earlier post.) Earlier post.)
