A new study, part of the Atlanta Commuter Exposures (ACE) Study, has assessed on-roadway in-cabin particulate pollution (PM 2.5 ) collected from scripted rush hour commutes on highways and on non-highway side streets. Most traffic pollution sensors are placed on the ground alongside the road and take continuous samples for a 24-hour period.

An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption. This is done via exhaust gas recirculation (EGR). —Patrik Soltic. The first results are very promising.

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. Further, the GDI particles carry numerous carcinogenic substances. Click to enlarge.
