Alcohol (FAEA) Content Increasing Effect on Exhaust Emissions and Gasoline Vehicle Performance 2000-01-1966

This study makes a technical evaluation on the possible impacts produced by a 22% to a 26% of fuel anhydrous ethyl alcohol (FAEA) content increase on gasoline, concerning exhaust emissions (CO, HC, NOx and Aldehydes), fuel consumption, vehicle performance (drivability) and engine performance on test bench.Performance curves of an 2.0 MPFI engine, emission and consumption tests on chassis dynamometer and drivability tests on three vehicles representing the national fleet are shown, with technologies considering the three limits established by Automotive Vehicles Air Pollution Control Program - PROCONVE.Results indicate fuel consumption increase and no significative changes of emissions, pursuant to anhydrous alcohol content increase above 22% vol. on gasoline.
