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.

Audi banking on Gen 2 3.0L TDI diesel for US sales; calls for a “fair shot” for diesel

Green Car Congress

Do they receive HOV access for their improved fuel economy and ultra low emissions? In fact in 6 of the states, diesel fuel is penalized with additional state taxes. So diesel fuel gets taxed twice or penalized twice at the federal and state level. Changes in the exhaust manifolds and turbo from Gen 1 to Gen 2.

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

Green Car Congress

To determine the vehicle efficiency effect of ethanol, they compiled paired energy efficiency data from all known studies of existing spark injection (SI)-engine vehicles operating on ethanol/gasoline blends and pure gasoline. Most of the studies expressed vehicle efficiency in various volume-based units. Credit: ACS, Yan et al.
