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.

India World leader in production and export of ethanol. The increased solubility of water with higher ethanol content permits E30 and hydrated ethanol to be put in the same tank since any combination of them always results in a single phase.
Retrieved 30 April Conversely, if the spark ignites the fuel prior to the piston coming past top dead center of its travel, the pressure wave may press down on the piston while it is still being driven up in the compression stroke, causing severe power loss, as the fuel ignition now works against the engine for a short while in i.c.egines of providing power to it.
Methanol fuel has received less attention than ethanol fuel as an alternative to petroleum based fuels. Also, the addition of ethanol in solutions with diesel fuel causes the cetane rating to drop and the heating values to be lower.
Balabin ; et al. Prairie Oak Publishing, Maryville, Missouri. Carbon dioxidea greenhouse gasis emitted during fermentation and combustion. Ethanol has most commonly been produced through fermentation of sugars, and methanol has most commonly been produced from synthesis gas, but there are more modern ways to obtain these fuels. Ethanol was fumigated into the intake air charge and introduced in the engine as a vapor or mist, dependent on the degree of vaporization which occurred.
Ethanol fuel – Wikipedia

Competitiveness Bio diesel initiatives underway U. Who Killed the Electric Car? The additive MTBE is currently being phased out due to ground water contamination, hence ethanol becomes an attractive alternative additive.
During a cold start pure gasoline is injected to avoid starting problems at low temperatures. Bi-fuel vehicle Flexible-fuel vehicle Hybrid vehicle Multifuel Plug-in hybrid. This causes the maximum pressure to build up on the piston because the cylinder volume is at its smallest. I.ce.ngines the spark ignites the fuel too late, the piston will have been pulled down somewhat in the cylinder and the power stoke will operate off of less compression, reducing the power delivered to the engine from that power stoke.
Brazil burns significant amounts of ethanol biofuel. 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.
Archived from the original PDF on 22 November The alcohol is then delivered to the carburetor where the vaporized alcohol is metered alcoho, mixed with air for proper combustion. The engine will run well in normal operation, but may have some starting problems on cold mornings and may misfire and overheat when accelerating very hard. Revenge of the Electric Car. A simple fumigation system was used, consisting of a single hole, direct opening configuration spraying nozzle.
Propanol and butanol are considerably less toxic and less volatile than methanol.
More alcohol fuel than diesel fuel is required by mass and volume. INEOS produced ethanol from vegetative material and wood waste.
ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES
Soluble contaminants, such as aluminium hydroxide, itself a product of corrosion by halide ions, clog the fuel system over time. There is lack of distribution points service stations where fuel is available to the public.
This means that almost twice as much alternatibe gasoline must be burned to give the same energy input to the engine. Energy portal Renewable energy portal Ecology portal Sustainable development portal. However, problems with cold start and WOT, which are open loop modes, could then be expected to occur if the fuel phase-separates.
