UC Berkeley study quantifies LD gasoline on-road emissions

Green Car Congress

Based on on-road measurements in their study, a team from the University of California Berkeley has estimated that, as of 2010, light-duty (LD) gasoline vehicles were responsible for 85% of CO; 18% of NO x ; 18% of organic aerosol (OA); and 6% of black carbon (BC) emissions from on-road motor vehicles in the United States.

Study finds ethanol blending appears to reduce significantly genotoxic emissions from gasoline direct injection vehicles

Green Car Congress

A research team from Empa (Swiss Federal Laboratories for Materials Science and Technology) and the University of Applied Sciences Bern, Laboratory for Exhaust Emission Control, reports that ethanol blending appeared to reduce genotoxic emissions from a flex-fuel Euro-5 gasoline direct injection (GDI) vehicle (a Volvo V60 with a 1.6

NYC had electric taxis in the ’90s—the 1890s, that is

Baua Electric

New York City’s iconic fleet of taxis once included some EVs—but you have to look back more than a century to find them. The fleet quickly grew from a dozen vehicles in 1897 to over 100 by 1899. The instant torque of electric motors and lack of exhaust noise have also created many a modern EV enthusiast.

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. —Zimmerman et al.

ICCT study concludes no technical barriers to use of higher blends of ethanol

Green Car Congress

Pressure on the RFS2 has increased as statutory mandated volumes of biofuel exceed the “blendwall” of 10% ethanol in gasoline. Primary technical concerns with using intermediate-level blends of ethanol in the vehicle fleet include: Fuel economy. the optimal air/fuel ratio for ethanol blends is lower than for pure gasoline.

Ford researchers report detailed study of the effect of different ethanol blend levels on emissions from FFVs

Green Car Congress

Future blending options for ethanol in gasoline include continuation of low-level blends (E0-E15), greater use of E85 in flexible fuel vehicles (FFVs), or new use of midlevel blends (E20-E40) in FFVs or in new vehicles designed with midlevel blend-capability. Engine-out exhaust contains typically 1?3% 99% of these organic compounds.23.

Verizon replaces 234 vans in New York City with hybrid vans using XL Hybrids technology

Green Car Congress

The New York State Energy Research and Development Authority (NYSERDA) and Verizon announced that Verizon has replaced 234 of its existing gasoline-powered vans with hybrid-electric vans for use in New York City. And with the addition of these hybrid vehicles, our fleet is as efficient as ever as we continue to use less fuel year after year.
