Unregulated Exhaust Emissions from Methanol-Fueled Cars 820967

This paper describes the characterization of regulated and unregulated exhaust emissions from two methanol-fueled automobiles. For comparison, two gasoline-fueled automobiles of the same make and model were also evaluated. These automobiles were evaluated over the Light-Duty Federal Test Procedure and the Highway Fuel Economy Driving Schedule. Additional evaluations with the methanol-fueled automobiles were conducted using promoted base metal catalysts, and one of these automobiles was tested in a non-catalyst configuration. Exhaust constiuents sampled for, in addition to the regulated emissions, include: aldehydes, particulate, individual hydrocarbons, methanol, ethanol, ammonia, cyanide, amines, nitrosamines, and methyl nitrite.
