Ethanol
With gas climbing and climbing, more people are turning to Ethanol. Then you hear that the E-85 Ethanol damages your engine. After doing some research I found:
An Alternative Fuel
Illinois leads the nation in the use of ethanol blended gasoline. Ethanol became a popular additive to boost the octane level of gasoline when environmental concerns resulted in the phase-out of leaded gasoline. Ethanol is an oxygenate, meaning it has a high oxygen content, burns more completely and pollutes less. Nearly half of the gasoline sold in Illinois contains 10 percent ethanol.
Illinois is taking the lead once again with the introduction and operation of one of the nation’s largest variable fuel fleets. These vehicles are capable of operating on E-85 or a blend of 85 percent ethanol and 15 percent unleaded gasoline. The 200 proof ethanol is made from Illinois corn. The small percentage of gasoline enhances starting in extremely cold weather.
The driving force for this blossoming automotive fuel technology is society’s multiple concerns of increasing air pollution from fossil fuels like gasoline, our dependence on foreign suppliers for half our fuel needs, and the dim prospects for gasoline in the future as the world’s oil supply dwindles.
The Illinois Corn Marketing Board brought the first E-85 car to Illinois in order to introduce the technology to the public. Governor Jim Edgar and the Illinois Department of Energy and Natural Resources introduced the state’s first fleet shortly after. This fleet of 12 Chevrolet Luminas was introduced in 1992, part of only 50 manufactured that year. E-85 cars are virtually identical to regular gasoline vehicles except for some variable fuel features. In 1996 Ford will manufacture 6,000 E-85 Tauruses equipped with 3.0L Vulcan. More than 350 E-85 cars are being tested by government and private business in Illinois today and they will enter mainstream commercial channels in 1996-97.
E-85 vehicles have been designed for versatility. They will operate with unleaded gasoline or any mixture of gasoline and ethanol up to an 85 percent concentration. A key component in all ethanol vehicles to date is a sensor which determines the percentage of ethanol in the fuel, optimizes performance and adjusts emission control devices.
