SwRI engineers develop near-zero emissions diesel engine technology; 90% reduction of NOx

Green Car Congress

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. g/hp-hr NO x emissions). SwRI developed the technology for the California Air Resources Board (CARB).

Researchers show mechanism by which diesel exhaust particles trigger respiratory “flare-ups”

Green Car Congress

Researchers at Imperial College London, working with colleagues from King’s College London and University of British Columbia, have demonstrated a mechanism by which diesel exhaust particles directly affect the lungs to initiate symptoms such as a tightening of the airways and cough.

US charges Audi manager with conspiracy to cheat US emissions tests; sacrificing NOx control for a sound system

Green Car Congress

The US has charged a former Audi manager via criminal complaint for his role in a conspiracy to defraud US regulators and customers by implementing defeat device software in thousands of Audi diesel vehicles to cheat US emissions tests. liter diesel engine employed Selective Catalytic Reduction (“SCR”) technology to reduce NO x emissions.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.

Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

A paper on the study is published in the journal Atmospheric Environment. However, both measurements also act as proxies for the complex mixture of gases in diesel exhaust, which is an established carcinogen and associated with respiratory, cardiovascular and reproductive health effects.
