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.

They are used only a very small percentage of the time, but when they are used, the ECU is running off of pre-determined parameters and is not able to adapt to differing fuel blends, unless special provisions are made to do so as in a flex fuel vehicle.
Recent research has demonstrated that complete dehydration prior to blending with gasoline is not always necessary. Alcohols have low sulphur content in the fuel.
Most methanol is produced from altenative gas, although it az be produced from biomass using very similar chemical processes. Retrieved 24 October The fraction of water that an ethanol-gasoline fuel can contain without phase separation increases with the percentage of ethanol.

Alcohol fuel – Wikipedia
This allowed the ethanol to be mixed with the intake air for a sufficient period, providing uniform mixing. Leon Duray qualified third for the Indianapolis auto race with an ethanol-fueled car. Ethanol fuel by country. N 2 to remove the adsorbed water. Share buttons are a little bit lower. Retrieved 22 January Archived from the original on 29 September Use of methanol, like ethanol, significantly reduces the emissions of certain hydrocarbon-related toxins such as benzene and 1, 3 butadiene.
In a study, complex engine controls and increased exhaust gas recirculation allowed a compression ratio of Ethanol fuel may also be utilized as a rocket fuel.
Retrieved 12 March 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 the primary source material for ethanol fuel production. It has high latent heat of vaporization which results in a cooler intake process.
Retrieved 3 August Retrieved 6 August Cellulosic ethanol production is a new approach that i.c.enggines alleviate land use and related concerns.
Royal Automobile Association of South Australia. For vehicles with fuel-tank mounted fuel pumps, additional differences to prevent arcing, as well as flame arrestors positioned in the tank’s fill pipe, are also sometimes used.
Archived from the original on 21 October Thus, many people will die due to lack of food. Nissan plans to create a technology that uses liquid ethanol fuel as a source to generate hydrogen within the vehicle itself. A simple fumigation system was used, consisting of a single hole, direct opening configuration spraying nozzle.
Archived from the original on 15 December Archived from the original PDF on 9 February The fuel mileage declines with increased water content.
ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES
Cellulosic ethanol can be produced from any plant material, potentially doubling yields, in an effort to minimize conflict between food needs vs. Alternativw feedstocks are considered renewable because they get energy from the sun using photosynthesis, provided that all minerals required for growth such as nitrogen and phosphorus are returned to the land. The heavier phase, poor in the entrainer benzene or cyclohexaneis stripped of the entrainer and recycled to the feed—while the xlcohol phase, with condensate from the stripping, is recycled to the second column.
Bio-ethanol is usually obtained from the conversion of carbon-based feedstock. Alcohol-fuelled engines generally have difficulty in starting at temperatures below 10 C.
This new process uses molecular sieves to remove water from fuel ethanol. This method is backed up by advanced knock sensors — used in most high performance gasoline engines regardless of whether they are designed to use ethanol or not — that detect pre-ignition and detonation.
