Study examines effect of different ethanol blends on criteria, GHG and unregulated pollutants 30 October 2011 A team from UC Riverside and the Pacific Northwest National Laboratory report in the journal Fuel on their study of the impact of different ethanol blends on criteria emissions (THC, NMHC, CO, NOx ); greenhouse gas (CO2 ); and a suite of unregulated pollutants in a fleet of gasoline-powered light-duty vehicles. The vehicles ranged in model year from 1984 to 2007 and included one Flexible Fuel Vehicle (FFV). They performed emission and fuel consumption measurements in duplicate or triplicate over the Federal Test Procedure (FTP) driving cycle using a chassis dynamometer for four fuels in each of seven vehicles. The test fuels included a CARB (California Air Resources Board) phase 2 certification fuel with 11% MTBE content; a CARB phase 3 certification fuel with a 5....
