Exhaust, evaporative, and refueling emissions were examined from a methanol-fueled Ford Escort operated with M-85 (85% methanol-15% gasoline) and M-100 (100% methanol) fuels. Exhaust and evaporative emissions were examined for vehicle operation at summer and winter ambient temperatures, while refueling emissions were examined at typical summer temperatures. Regulated emissions (total hydrocarbons, carbon monoxide, nitrogen oxides), as well as, formaldehyde, methanol, and detailed hydrocarbon emissions were examined. Results indicated that carbon monoxide, methanol, hydrocarbon, and formaldehyde exhaust emissions increased substantially when the vehicle was operated at reduced temperatures. Formaldehyde emissions were more fuel sensitive than hydrocarbon, carbon monoxide and methanol emissions. With M-85 a significant portion of the total organic evaporative and refueling emissions was comprised of hydrocarbons. Both hydrocarbon and methanol evaporative emissions were dependent on test temperature as well as on fuel type. Methanol refueling emissions were invariant to both tank temperature and fuel type, while hydrocarbon refueling emissions decreased with increasing tank temperature.
