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.

Achates near-zero heavy-duty opposed-piston diesel enters fleet service; compliant with 2027 NOx levels

Green Car Congress

It is the only diesel engine operating on the road capable of meeting CARB’s 2027 regulation, which requires a 90% reduction in emissions of NO x compared to current standards. The catalyst light-off mode delivers the capability that allows Achates to manage extremely low engine-out NO x and also very high exhaust gas temperatures.

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. 10 ) of urban air, a fraction known to be enriched with non-tailpipe constituents.

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).

Mayor of London floats action plan to reduce city’s air pollution

Green Car Congress

The Mayor of London, Sadiq Khan, has outlined plans to crackdown on the most polluting vehicles, including an additional £10 (US$13) per day charge for the most polluting vehicles and an extended Ultra-Low Emission Zone. The public has until 29 July 2016 to provide feed back on the first round of the Clean Air Plan consultation.
