Can alcohol be used for IC engine?
Alcohol type of fuels is alternative to petroleum-based fuels due to reduced greenhouse gas emission, toxic exhaust emission and enhancement of overall energy efficiency. Moreover, they are convenient for internal combustion engines due to their high octane rating, burning velocities and wider flammability limits.
Why alcohols Cannot be used in SI engines?
Explanation: Alcohols have high self-ignition temperature and low latent heat of vaporization. That is why they cannot be used in CI engines.
Why do we not use ethanol directly in IC engine?
Ethanol’s high-octane number – an advantage in SI engines – is a disadvantages for use in CI engines. Ethanol is unlikely to auto‐ignite under the conditions existing in standard diesel engines. In short, when using ethanol ignition starts later than with pure diesel, but the combustion time does not change.
Why is ethanol a better fuel than methanol?
On the other hand, ethanol is less chemically toxic than methanol, and it carries more energy per gallon. Ethanol contains about 75 percent of the energy of gasoline per gallon, compared to 67 percent for methanol. A fuel system made acceptable for methanol use will also be fine for ethanol or pure gasoline.
Can you use vodka as fuel?
Water is generally found in small amounts in fuel systems anyhow, due to condensation, contamination etc, so an engine HAS to be able to deal with that to some extent. So, as long as the ratio of “real fuel” and vodka is low, most likely nothing will happen.
What happens if you put alcohol in your gas tank?
The principle behind pouring alcohol in the gas tank is as follows: When alcohol is added to a gas tank with water and gasoline in it, the alcohol sinks to the bottom and absorbs the water, forming a combination that is no longer harmful to your car’s engine.
Where are alcohols used as fuels?
Various alcohols are used as fuel for internal combustion engines. The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
Which are the two main alcohol used in the engine as a fuel?
Explanation: Alcohols have been used as engine fuels for a long time, methanol and ethanol are the two main alcohols used in the engine as a fuel.
What are the disadvantages of power alcohol?
Disadvantages of using alcohol as a fuel
- Calorific value of alcohols are almost half to that of gasoline.
- Combustion of alcohols produce aldehydes.
- Alcohol is corrosive in nature.
- It is difficult to start the engine when the temperature of the engine is below 10 °C while using alcohol.
Why is methanol not used as a fuel?
The Chinese have a million methanol cars on the road and will be carrying these supplies back to China to power their growing transport sector. Yet the EPA continues to refuse to allow methanol to be used in car engines, mainly because of the reputation earned as a poisonous “wood alcohol” during Prohibition.
What is the best fuel for an IC engine?
4. ALCOHOL AS FUEL…. Liquid fuels are preferred for IC engines because they are easy to store and have reasonably good calorific value. The main alternative is the alcohol. Alcohols are attractive alternate fuels because they can be obtained from both natural and manufactured sources.
What are the disadvantages of alcohol in an engine?
Alcohol is more corrosive on copper, brass, aluminium etc. this cause deteriorate action on engine, gasket, fuel line and fuel tank. This put some restriction (selection of material) in the engine design and manufacturing process. The strong odor alcohol cause headaches, dizziness, and many people find it is offensive.
Why alcohol is not used as a fuel in cars?
In which ethanol is the most widely used alcohol because of its abundance and leas toxicity. More complex alcohol is not popular as fuel because they are not commercially viable. In theory, the alcohol is get completely oxidized in the engine and get convert it into the carbon dioxide and water.
What are the dangers of alcohol in catalytic converters?
Alcohol produces invisible flames, which is considered as dangerous in fuel handling. This problem can be overcome by adding fuel additives. Lower exhaust temperature results longer time to heat the catalytic converter. Catalytic converter takes some time to get its efficient operating temperature.
