U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

A study of emissions from gasoline direct injection (GDI) vehicles in an urban near-road environment in Toronto over a wide range of weather conditions (February 2014 to January 2015) found that—other than for NO x and CO—the GDI engines had elevated emissions compared to the Toronto fleet.

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. With that as a premise, they go on to show that the efficiency of existing vehicles can be both positively and negatively affected by ethanol content, ranging from ?15% 15% to +24%.
