Exhaust, Pollution and Switzerland

Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters

Green Car Congress

MAY 23, 2014

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.

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.

JULY 14, 2017

A new study by an international team led by researchers from the Paul Scherrer Institute (PSI) in Switzerland has found that modern diesel passenger cars equipped with diesel particulate filters (DPFs) emit fewer carbonaceous particulates than gasoline-powered vehicles. The open-access study is published in the journal Scientific Reports.

APRIL 5, 2009

Air pollution. Emissions of regulated air pollutants from vehicles continue to fall across EEA member countries but concentrations remain high in some urban areas. The number of kilometers travelled by passengers in EEA member countries grew by 1% (equivalent to 65 million kilometers) in 2006. Transport at a crossroads.

The researchers, involving scientists from Germany, the United Kingdom and Switzerland, concluded that the limit is 1,000 billion tonnes of carbon dioxide between the years 2000 and 2050. Strong mitigation actions according to the blue route would limit the risk of exceeding 2°C to 25%. Meinshausen et al. 2009) Click to enlarge.
