Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group. The Working Group consists of members undertaking research and development in the field of hydrogen combustion in an opposed-piston engine. The only criteria emission of concern is NO x.

Swiss team concludes that particulate filters should be mandatory for GDI engines

Green Car Congress

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.

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

Green Car Congress

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. —Platt et al.

Study finds modern diesel cars emit fewer carbonaceous particulates than gasoline cars

Green Car Congress

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.
