11. Production of Methanol from Lignite or Coal

12. Production of Methanol from Municipal Solid Wastes

13. Production of Ethanol from Grains

14. Production of Ethanol from Sugarcane

15. Alcohols for SI engines
Alcohols having antiknock characteristic compared to gasoline because
higher compression ratio of 11:1 and 13:1 to 7:1 or 9:1. Alcohol
produces fewer harmful exhaust emissions. It contains about half the
heat energy of gasoline per liter. A carburetor or fuel injector fuel
passages should be doubled in are to allow extra fuel flow.
It does not vaporize as easily and its latent heat of vaporization is much
greater. This affects cold weather starting.
