A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes. —Platt et al.

Air pollution externalities of 12–14 ton HGV on highway (Euronorm III) in euro cents. A new report from the European Environment Agency (EEA) suggests that new road charges for heavy goods vehicles (HGVs or lorries) should reflect the varied health effects of traffic pollution in different European countries.

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. —Norbert Heeb.

Stuart Grange works in Empa’s Air Pollution/Environmental Technology Laboratory and also at the Wolfson Atmospheric Chemistry Laboratories at the University of York. Together with his colleagues, he used a special instrument to examine the exhaust plumes of 23,000 passing cars and analyzed the levels of NO x and CO 2.

OP engines utilize direct injection after ports closure to avoid the risk of fuel short circuiting out the exhaust. The University’s Engine Research Center is dedicated to investigating the fundamental thermo-physical process that control combustion performance and pollutant emissions formed during combustion in internal combustion engines.
