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. The first is a non-polar substance and the second is a bipolar mixture.

Study finds Tula dDSF software reduced NOx 41% and CO2 9.5% in Leibherr D966 diesel

Green Car Congress

At the International Engine Congress in Baden-Baden (Germany), Liebherr-Components AG and US-based Tula Technology presented the results of their joint study on heavy machinery. Based on simulations, Tula’s diesel Dynamic Skip Fire (dDSF) software ( earlier post ) allowed the reduction of NO x tailpipe emissions by 41% and CO 2 by 9.5%.

JATO: new car CO2 emissions rise for the first time in a decade in Europe; diesel down, gasoline up, SUVs up

Green Car Congress

This rise in average CO 2 emissions correlates with a decrease in demand for diesel cars across Europe—which produce lower CO 2 emissions than gasoline cars—and the rising popularity of SUVs, which emit higher average CO 2 emissions of 133.0 In turn, diesel cars accounted for just 43.8% g/km—a difference of 5.5

Tech: New Technology Reduces Diesel Emissions

Clean Fleet Report

According to dozens of automotive story headlines, the internal combustion engine, running on gasoline or diesel, is dead or dying as customers, auto companies and investors flock to electric powertrains. While 2045 may still be more than two decades away, emissions advances in internal combustion engines (ICE) are continuing.

Electric cars in UK cleaner than best diesels in summer, not yet in winter

Green Car Reports

This has led to the scrutiny of electric cars to determine whether their overall "wells-to-wheels" carbon footprints exceed those of regular vehicles powered by internal-combustion engines. Although electric cars do not emit exhaust, it's widely recognized that the electricity to charge their batteries often still comes from fossil fuels.
