Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. By contrast, diesel cars with particle filters exceeded the limit only 45-fold.

Traffic contributes more to NO x emissions in Europe than previously thought, according to a new study by a team at the University of Innsbruck. The majority of the emissions is caused by diesel cars. An open-access paper on their work appears in Scientific Reports. TWC treatment can lead to a 10 fold reduction of NO.
