Abstract
Methyl alcohol (methanol) can be made from coal and waste products with reasonable thermal efficiency. Strong interest in blending this liquid fuel with gasoline for automotive use has developed. A research program is described which characterized the behavior of methanol-gasoline blends in spark ignition engines, particularly those used in automobiles. The program included: characterizing octane ratings of methanol-gasoline blends, a single cylinder engine study of the effects of engine parameter variations on emissions and fuel economy of methanol-gasoline blends, and a simulated vehicle program to determine the behavior of the blends for the federal emissions test procedure. Results indicated that no substantial changes in emissions or fuel economy should be expected from operating blends of 10 percent or less in existing vehicles. Performance, vapor lock, phase separation, and corrosion problems are pointed out.Keywords
