Bioethanol, a substitute for gasoline?

Bioethanol is a fuel's environmental, chemical formula is the same as the ethyl alcohol found in alcoholic drinks. Raw materials that produce ethanol, is represented by scrap wood (lumber, wood chips, recycled paper), sugar cane, sugar beet, corn, etc… Bioethanol is used as an alternative to gasoline in different proportions mixed with, or pure (E100).
In terms of ethanol's characteristics, it has a higher octane than gasoline, hence resulting in more efficient combustion (default and lower CO2 emissions than in gasoline engines, which work only, no sulfur and hydrocarbon emissions ). The energy per liter is smaller (34%), requiring more fuel for the same number of miles. To achieve a more efficient car, it must be equipped with an engine designed to work exclusively with bioethanol, which is an engine with a compression ratio of greater fuel mixture (values close to 20:1). The only current vehicles with engines specially designed to run on bioethanol are buses and trucks, Scania is one of the pioneers in this field.
Brazil is the country with the longest tradition's use of ethanol, now used at a rate of approximately 30% of all automotive fuels. This helps the sugar cane plantations (raw material from which one can produce bioethanol), which are harvested 3-4 times per year.
Environmental regulations currently in force in the U.S. and Europe provide the use of ethanol and gasoline blend fuels in different proportions. Future plans allow increasing ethanol's share in order to reduce greenhouse gas emissions create the greenhouse effect. Bioethanol E85 Ethanol is popular with a concentration of 85% ethanol and is flexible for engine fuels legally accepted. In winter, however a minimum of 25% gasoline mixture is needed for cold starting.
