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

Green Car Congress

A team at Ford Motor Company’s Research and Innovation Center in Dearborn conducted a detailed study of the effect of ethanol blend level in emissions, using a 2006 model Mercury Grand Marquis flexible fuel vehicle (FFV) operating on E0, E10, E20, E30, E40, E55, and E80 on a chassis dynamometer. Engine-out exhaust contains typically 1?3%
