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.

CRC study finds some adverse results from use of mid-level ethanol blends in MY 2001-2009 engines; DOE and ethanol industry say study significantly flawed

Green Car Congress

The study claims mechanical damage and suggests degraded engine performance, emissions and durability on conventional vehicles from the use of E15 or E20 fuel. Growth Energy, an ethanol industry trade group, petitioned the EPA in March 2009 to raise the limit on ethanol in gasoline from 10 to 15 percent. Background. Earlier post.)

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Researchers at the University of Wisconsin, led by Dr. Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time.
