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%

CMU team identifies IVOCs emissions from on-road gasoline vehicles and small off-road engines as important SOA precursors

Green Car Congress

However, only a small fraction of SOA formed during photo-oxidation of dilute LDGV exhaust in a smog chamber is explained by single-ring aromatic compounds. The relationships between IVOCs and other pollutants were examined to develop methods for estimating IVOC emissions from existing data. Gordon et al. —Zhao et al.

The only reason we used gasoline was for comparison; it wasn’t necessary. As comparison, again excluding private stations, there are 298 biodiesel stations; 8,485 electric plug-in stations; 2,391 E85 stations; 12 hydrogen stations, 56 LNG stations, and 2,718 LPG stations. The exhaust ports are also designed for greater flow.
