- 1. ALTERNATE FUELS Alcohol, Hydrogen, Compressed Natural Gas, Liquefied Petroleum Gas and Bio Diesel - Properties, Suitability, Merits and Demerits - Engine Modifications.
- 2. Alternative Fuels • Alcohols • Vegetable oils • Biodiesel • Biogas • Natural gas • Liquefied Petroleum Gas (LPG) • Hydrogen
- 9. Alternative fuels in Engine
- 11. 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.
