Demonstration of the compatibility of methanol gasoline blends (blended at the 5V % level with an equal amount of cosolvent gasoline grade tertiary butyl alcohol) with automotive pollution control systems has been an on-going program with ARCO Chemical Company. The continuing program consists of matched pairs of late model vehicles which accumulate miles from new on either a commercial base alcohol free gasoline or an alcohol blend gasoline. Mileage accumulations on the vehicles is accomplished using trained drivers covering an on-the-road course incorporating a mix of city and highway driving conditions with total mileage accumulation reaching 50000 miles in 24 months or less. Vehicles are tested at specified intervals during their mileage accumulation. This testing consists of SHEDs (Sealed Housing for Evaporative Determinations) as well as Federal Test Procedure tail pipe emissions. The data contained in the paper is from the 1985 fleet of test vehicles, which were predominately fuel injected vehicles.
