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 fuel

Alcohols have higher flame speed. Emissions from an engine using M10 fuel are about the same as those using gasoline.

Yeasts as production organisms for butanol have decisive advantages compared to bacteria. However, enormous increase in number of vehicles has started dictating the demand for fuel. The graph on the right shows figures calculated by the UK government for the purposes of the Renewable transport fuel obligation. Archived from the original PDF on 21 August The principle reason for blending some gasoline into ethanol for flex fuel vehicles is to improve starting in cold weather.

The technology uses heat to reform ethanol into hydrogen to feed what is known as a solid oxide fuel cell SOFC. Fuel cell vehicle Hydrogen economy Hydrogen vehicle Hydrogen internal combustion engine vehicle. This means that almost twice as much as gasoline must be burned to give the same energy input to the engine. Once again, automobiles built in or later will have some protection against this varnishing action. Ethanol is commonly made from biomass such as corn or sugarcane.


Certain additives may be added to motor oil in order to neutralize these acids.

Because absorbed water dilutes the fuel value of the methanol although, it suppresses engine knockand may cause phase separation of methanol-gasoline blends, containers of methanol fuels must be kept tightly sealed.

About project SlidePlayer Terms of Service. As of [update]small quantities of ethanol are used in lightweight rocket-racing alternatige. Methanol fuel and Ethanol fuel.

Glucose a simple sugar is created in the plant by photosynthesis. Some engines just use data computed by the ECU from the map and from the engine position and speed sensors.

The gasoline fraction is obtained by the fractional. Most alternate fuels are very costly at present since the quantity used is very less. The whole idea is that the HO2 sensor feeds back data as to whether the engine is running i.c.ehgines or lean the lambda and the ECU dynamically uses this data to keep the engine running at an optimum level.

Methanol is hygroscopic, meaning it will absorb water vapor directly from the atmosphere. Royal Automobile Association of South Australia. Ethanol fuel by country. Diesel fuels serve as lubricants for diesel engine.


The concentration of each gas is measured relative to the sample taken continuously and digitally. Some smart flexible fuel or variable fuel engines are capable of using any random mixture combination of methanol and gasoline ranging from methanol to pure gasoline. Russi 7 March The New York Times.

Alcohol fuel – Wikipedia

A fuel pre-heater assembly utilizing waste heat from the engine may also be provided. Alcohols have an almost invisible flame, which is considered dangerous when handling fuel.

Agricultural 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.

However, as a result, the use of GAIAX came to be considered an act of smuggling in Japan by the government and the petroleum industry. The stoichiometric ratio for pure ethanol is approximately 9:
