ALCOHOL AS AN ALTERNATIVE FUEL IN I.C.ENGINES PDF

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.

indiatechnical: PPT ON ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES

This approach would have a smaller carbon footprint because the amount of energy-intensive fertilisers and fungicides remain the same for higher output of usable material. Retrieved 18 March Also, the CO and HC emissions were always higher when using the blended fuels than when the engine operated with fumigation. Archived from the original PDF on 12 February The fast rise in temperature may trigger the next major ice sooner than it would otherwise occur, due to switching off Atlantic Ocean currents.

It requires a minimum of modification to the engine, since alcohol injector is placed at the take air manifold. i.c.ehgines

The most common methods for achieving alcoholl fuel operation are 1. The problems of water absorption into pre-mixed gasoline causing phase separationsupply issues of multiple mix ratios and cold-weather starting are also avoided. A fixed injection timing and 18 compression ratio were used throughout the experiments.

United Nations Environment Programme. 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.

The first process, used in many early fuel ethanol plants, is called azeotropic distillation and consists of adding benzene or cyclohexane to the mixture.

Use as internal combustion engine fuel Both methanol and ethanol burn at lower temperatures than gasoline, and both are less alcohoo, making engine starting in cold weather more difficult.

A MIT study and an earlier paper published by the Society of Automotive Engineers identified a method to exploit the characteristics of fuel ethanol substantially more efficiently than mixing it with gasoline.

Methanol is very corrosive on metals.

The gasoline quality method was revised under the pretext of safety concerns in The company Energy Environment International developed a method for producing butanol from biomass, which involves the use of two separate micro-organisms in sequence to minimize production of acetone and ethanol byproducts.

Retrieved 22 January Ethanol is hygroscopicmeaning it absorbs water vapor directly from the atmosphere. If ethanol is then placed in the gas tank, it may dissolve off the varnish which will travel, in clumps of gunk, into the fuel filter and clog up the fuel system. They are mostly removed during ethanol purification.

Alcohol fuel

Recent research has demonstrated that complete dehydration prior to blending with gasoline is not always necessary. Halide ions increase corrosion in two ways: Archived from the original PDF on 5 October Archived from the original PDF on 28 Alcohok Instead of utilizing only the starch by-products from grinding wheat and other crops, cellulosic ethanol production maximizes the use of all plant materials, including gluten.

Revenge of the Electric Car. The cold cranking mode of operation lasts only a very short while on any cold start, and represents a very small part of the overall engine operation. The graph on the right shows figures calculated by the UK government for the purposes of the Renewable transport fuel obligation.

alfernative Furthermore, the manufacturers are required to warrant pollution control limits for the life of the vehicle. From tothe share of ethanol in global gasoline type fuel use increased from 3.

Archived from the original pdf on Alcohols have higher flame speed. However, it is difficult to smell methanol in the air at less than 2, ppm 0. Using a variable geometry or twin scroll turbochargerthe compression alcojol can be optimized for the fuel, making fuel economy almost constant for any blend.

However, since propanol is harder to produce than methanol biologically OR from oilmethanol-utilising fuel cells are preferred over those that utilise propanol. Because of the high cost of petroleum products, energy securityemission problems some developing countries are trying to use alternate fuels for their vehicles.

Finally, the Ministry of Alcoyol, Trade and Industry also joined this campaign.
