3rd Year Seminar ReportOn ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES Undertaken by: MITHUN SARKAR Roll No IC engines because of their high octane rating, burning velocities, and wider Appendix A. Both acts are mandating the procurement of alternative fuel vehicles. Alcohols have been used as a fuel. The first four aliphatic alcohols are of interest as fuels . into its main agenda. Alcohol fuels had become part of five main alternative fuels: Two of which were alcohols; methanol and ethanol.

Alcohol contains oxygen and thus requires less air for stoichiometric combustion. There is the danger of storage tank flammability, due to low vapor pressure. However, the commercial manufacture and sale of any new fuel may be barred by existing laws that currently exclude GAIAX from the market.

Alcohol fuel

Archived from the original PDF on 28 September Because of the high cost of petroleum products, energy securityemission problems some developing countries are trying to use alternate fuels for their vehicles.

Ethanol fuel in Brazil. It will lose fue and have poor fuel economy, as well as produce an excess of the pollutants carbon monoxide CO and unburned hydrocarbons particulates. The fraction of water that an ethanol-gasoline fuel can contain without phase separation increases with the percentage of ethanol. The principle reason for blending some gasoline into ethanol for flex fuel vehicles is to improve starting in cold weather.

Enzymes can be used instead of fermentation.

Ethanol fuel – Wikipedia

I.c.engones 10 Altenrative The engine was coupled to an electrical generator through which load was applied by increasing the field voltage.

In JuneNissan announced plans to develop fuel cell vehicles powered by ethanol rather than hydrogenthe fuel of choice by the other car manufacturers that have developed and commercialized alterhative cell vehicles, such as the Hyundai Tucson FCEV apternative, Toyota Miraiand Honda FCX Clarity. The pump delivers pressurized liquid alcohol to the primary heat exchanger where the alcohol fuel is heated above the vaporization point at ambient pressure.

Mobile sources Gasoline car: Cellulosic ethanol offers promise because cellulose fibers, a major and universal component in plant i.c.eengines walls, can be used to produce ethanol. Welbaum 12 September Formula One racing continues to use gasoline as its fuel, but in pre war grand prix racing methanol was often used in the fuel.

Alcohol is much more alcohool than gasoline on copper, brass, aluminum, rubber, and many plastics. This is because of the lower air-fuel ratio needed by alcohol.

Ethanol is also miscible in water and any water carried by ethanol fuel may corrode parts of the fuel system. Retrieved 3 May However, it is difficult to smell methanol in the air tuel less than 2, ppm 0.

Sweden has a similar seasonal reduction, but the ethanol content in the blend is reduced to E75 during the winter months. A small amount of gasoline removes this danger.

Indicators on the test bed show the following quantities which alcohlo measured electrically: An additional complication is that production requires tilling new soil [75] which produces a one-off release of GHG that it can take decades or centuries of production reductions in GHG emissions to equalize. A fuel pre-heater assembly utilizing waste heat from the engine may also be provided.

Archived from the original PDF on 28 May I.c.enginee this process, ethanol vapor under pressure passes through a bed of molecular sieve beads. Alcohol fuel Biobutanola gasoline replacement. One liter of ethanol contain The technology for producing cellulosic ethanol is currently in the commercialization stage.

ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES

vuel The poor auto-ignition capability of alcohols is responsible for severe knock due to rapid burning of vaporized alcohol [1,4] and combustion quenching caused by high latent heat of vaporization and subsequent charge cooling. Ethanol research focuses on alternative sources, novel catalysts and production processes. It is therefore acceptable to the EPA for it to be inefficient, as long as the HO2 sensor heats up rapidly and transitions the ECU into closed loop operation in a short period of time.

Ethanol is already being used extensively as a fuel additiveand the use of ethanol fuel alone or as part of a mix with gasoline is increasing. Retrieved 14 October Archived from the original on 28 August E85 as a fuel is widely used in Sweden and is becoming increasingly common in the United States, mainly in the Midwest where corn is a major crop and is apcohol primary source material for ethanol fuel production.

The gasoline fraction is obtained by the fractional. Alcohols have an almost invisible flame, which is considered dangerous when handling fuel. During ethanol fermentationglucose and other sugars in the corn or sugarcane or other crops are converted into ethanol and carbon dioxide. With equal thermal efficiency and similar engine output usage, twice as much fuel would have aocohol be purchased, and he distance which could be driven with a given fuel tank volume would be cut in half.

The vehicle would include a tank for a blend of water and ethanol, which is fed into an onboard reformer that splits it into pure hydrogen and carbon dioxide.

It is also possible to generate ethanol out of cellulosic materials. In actuality, the engine does not have to be fully warmed up; it is only necessary that the heated oxygen sensor HO2 sensor is heated up to around degrees, which is necessary for its proper operation. Project Gaia is a U. The fuel cell generates electricity to supply power to the electric motor driving the wheels, through a battery that handles peak power demands and stores regenerated energy.

If an engine is limited in power output due to smoke emissions, fumigated ethanol could increase the power output because alcohol tends to reduce smoke. Brazil burns significant amounts of ethanol biofuel.

Leon Duray qualified third for the Indianapolis auto race with an ethanol-fueled car. If as much alcohol fuel was consumed as gasoline.
