As a result of the past decade of evaluation, the technical feasibility of alcohols as extenders and substitutes for gasoline in spark ignited engines has been generally established both with regards to performance and emissions. One of the problem areas is cold starting and warm-up driveability. High heats of vaporation and low vapor pressures at low temperatures of the alcohols are the cause of these problems. Current solutions include electric heating, separate fuel supply, and the addition of volatile components to the alcohol such as gasoline, isopentane and dimethyl ether. The alcohols typically are as clean burning or cleaner burning than gasoline. The effect on regulated emissions from using additives needs to be included in the evaluation of cold starting additives. This assessment should include consideration of total hydrocarbons as well as detailed hydrocarbons for photochemical impact and flame ionization detector responsivity. This paper presents an examination of the emissions evidence from two three-way catalysts equipped vehicles: A 1980 Ford Pinto and a 1981 Volkswagon Rabbit. The test fuels were neat methanol and a 5.5% (by mass) isopentane/methanol blend.
