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.

Emissions .ic.engines an engine using M10 fuel are about the same as those using gasoline. It requires a minimum of modification to the engine, since alcohol injector is placed at the take air manifold. Retrieved 30 May Liquid fuels are preferred for IC engines because they are easy to store and have reasonably good calorific value. This is because of the lower air-fuel ratio needed by alcohol.

My presentations Profile Feedback Log out. The bead’s pores are sized to allow adsorption of water while excluding ethanol.

Ethanol fuel

The engine is naturally aspirated and water cooled. I.cengines from ” https: The fuel mileage will likely suffer because ethanol is an oxygenated fuel and, particularly, if the ignition timing is not dynamically alterable. Since there have also been ethanol engines based on the diesel principle operating in Zlternative.

It is also important that the open loop modes of operation not be ignored. Consequently, the engine is operating open loop for the brief time that it is in WOT until the driver eases off the accelerator.

Ethanol is subsequently isolated and purified by a combination of adsorption and distillation. Alcohols have poor ignition characteristics n general. Alcohols have low sulphur content in the fuel. Archived from the original on 12 February alvohol Methanol fuel has been proposed as a future biofuel, often as an alternative to the hydrogen economy.

During a cold start pure gasoline is injected to avoid starting problems at low temperatures.

Chemistry Combustion and Alternative Fuels. A rich mixture will tend to make the engine run cool for two reasons: The raw energy-per-volume numbers produce misleading fuel consumption numbers however, because alcohol-fueled engines can be made substantially more energy-efficient.

ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES

Archived from the original on 28 August Carbon dioxidea greenhouse gasis emitted during fermentation and combustion. As early asChina has made alcohol fuel powered cars. The additive MTBE is currently being phased out altegnative to ground water contamination, hence ethanol becomes an attractive alternative additive. It is also possible to generate ethanol out of cellulosic materials. January Learn how and when to remove this template message.

Types of Emissions Emission Control Devices. Methanol is the simpler molecule, and ethanol can be made from methanol. The Clean Air Act requires the addition of oxygenates to reduce carbon monoxide emissions in the United States.

The poor refuse to grow fuel for the rich”.

Alcohol fuel – Wikipedia

Unsourced material may be challenged and removed. As a result, Brazilian flex vehicles are built with a small secondary gasoline reservoir located near the engine. Archived from the original on 6 May The Swiss company Butalco GmbH uses a special technology to modify yeasts in order to produce butanol instead of ethanol.

Compared to bioethanol, the primary advantage of methanol biofuel is its much greater well-to-wheel efficiency. University of Minnesota researchers report that if all corn grown in the U.

Of sugar beet Plants we get kg. Archived from the original on 6 December From Wikipedia, the free encyclopedia. However, the need to do this alternztive reduces the attractiveness of alcohol. Gasoline C made with Hydrous Ethanol.

Particulate exhaust emissions were drawn using a special sampling probe. A calculation should include:.
