Characterization of exhaust emissions from alcohol-fueled vehicles. Final report
The report describes the laboratory effort to develop analytical techniques to characterize exhaust emissions from neat methanol and ethanol-fueled vehicles. Analytical techniques were developed or modified to allow the measurement of methanol, ethanol, aldehydes and ketones, methyl nitrite, and formic and acetic acid in both raw and CVS-diluted exhaust. The methods were validated, qualified, and then used to evaluate exhaust emissions from a 1981 Ford Escort chassis with a 1983 1.6-liter methanol-fueled Ford Escort engine. The vehicle was evaluated over the Light-Duty Federal Test Procedure (FTP) and at 30 and 55 mph steady-state operation both with and without a catalytic converter. In addition to testing conducted with the 90% methanol/10% gasoline fuel blend for which the Ford Escort engine was designed, testing was also conducted with 100% methanol fuel. Other areas investigated included unburned fuel hydrocarbon composition, FID response correction for alcohols as compared with propane, and losses of unburned fuel and aldehydes in the sampling system.
