Ethanol Fuel
Ethanol fuel is a fuel that is not used in pure form. To use this fuel, it is mixed with gasoline in certain proportions and used as fuel. This process is used to reduce air pollution and reduce the use of fossil fuels.
Ethanol is a chemical fuel obtained by fermentation of natural sugar. Ethanol, also known as ethyl alcohol, is obtained from agricultural products such as corn, sugar cane and sugar beet. Since it is obtained from plants, it does not harm the environment as much as fossil fuels. Since the effort spent to obtain ethanol is 30% more than the energy given by the extracted ethanol, it does not have the power to compete with fossil fuels.
There is one aspect that should be considered in ethanol mixtures, which is that as the amount of ethanol in the mixture increases, its compatibility with gasoline engines decreases. Ethanol fuel has a value of 116 AKI and 129 RON, while gasoline has a value of 86-86 AKI and 91-92 RON. Therefore, the mixing ratio should be carefully adjusted according to the gasoline engine or some modifications should be applied to the engine according to the desired mixture. These modifications require compression ratio change, ignition timing and fuel pump replacement.
Engines running on ethanol need a cold start system to work in cold temperatures.
Is ethanol harmful to the environment?
Since ethanol is produced from organic raw materials, its harm to the environment is minimal. The only comparable situation in this regard is the large agricultural land and the amount of water to be used to produce sugar cane and corn, which are the raw materials of ethanol.
