2.  Ethanol has been known as a fuel for many
decades.
 How ever it is not widely used because of its high
price.
 Ethanol has some advantages over gasoline, such as
better anti-knock characteristics and the reduction of CO.

3.  Although having these advantages, due to limitation
in technology and economic, alcohol fuel still cannot be
used extensively.
 Using ethanol blended with gasoline is better than
pure gasoline because of its renewability and less toxicity.

6.  Ethanol (C2H5OH) is a pure substance. And
gasoline is composed of C4-C12 hydrocarbons.
 Ethanol contains an oxygen atom so it viewed as a
partially oxidized hydrocarbons.
 Ethanol is completely miscible with water in all
proportions, while the gasoline and water are immiscible.

7.  Ethanol fuel has high octane rating and therefore it is
considered efficient in terms of performance.
 The combination of 15% gasoline and 85% ethanol
is really helpful in starting engine in cold weather.

8.  All gasoline vehicles in use in the U.S. today can
accept gasoline blended with up to 10% of
ethanol(GASOHOL)
 Flexible fuel vehicles are cars and trucks that can
use any level of ethanol up to 85%.

9.  Produced renewably from agricultural crops or from
recylced wates.
 Used as motor fuel offers a way to reduce greenhouse
gas emission from transportation sources.

10.  Ethanol is used along or along with gasoline
concentrations to improve the working of engine.
 Hence many types of ethanol like E85 containing 85%
ethanol and 15% natural gas is a growing market today.
 E85 is produced in mid western Europe expecially where
there is abundance of corn crop.

11.  The automotive industry can be an important industry of
any country. However it facing crisis since the fuel prices.
 The ethanol car engines are really environment friendly.
 In order to reduce the burden of foreign oil from
economy it is important that we switch to ethanol cars.

13.  In this study, we found that using ethanol-gasoline
blend, CO emission may be reduced by 10-30%.
 While CO2 emission increases by 5-10%
depending on engine condition.
 The engine power and specific fuel consumption
increase approximately by 5% and 2-3% respectively.
