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.

Ethanol fuel
Yeasts as production organisms for butanol have decisive advantages compared to bacteria. Cellulosic ethanol can be produced from any plant material, potentially doubling yields, in an effort to minimize conflict between food needs vs. It is very clear that by increasing the amount of water in fuel ethanol one can reduce the corrosion. This flexibility enables diesel engines, equipped with the fumigation system, to be operated with diesel fuel only.
A calculation should include:. The engine can switch from dual fuel to diesel fuel operation and vice-versa by disconnection and connection of the alcohol source to the injector.
Revenge of the Electric Car. The fermentation processes to produce propanol and butanol from cellulose are fairly tricky to execute, and the Weizmann organism Clostridium acetobutylicum currently used to perform these conversions produces an extremely unpleasant smell, and this must be taken into consideration when designing and locating a fermentation plant. It is also possible to generate ethanol out of cellulosic materials.
All of these steps require resources and an infrastructure.
ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES
If an engine is limited in power output due to smoke emissions, fumigated ethanol could increase the power output because alcohol tends to reduce smoke. Retrieved 20 January During combustion, ethanol reacts with oxygen to produce carbon dioxide, water, and heat:.
Turon 25 November Leon Duray qualified third for the Indianapolis auto race with an ethanol-fueled car. It has poor cold weather starting characteristics due to low vapor pressure and evaporation. Engines External combustion engine Internal combustion engine Steam engine Gas turbine engine Steam engine Gas turbine engine.

Balabin ; et al. Two fuel tanks are used and various flow rates of the two fuels can be pumped to the engine, passing through a mixing chamber.
University of Minnesota researchers report that if all corn grown in the U. Nature 7 December 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. Archived from the original on Consequently, the engine is operating open loop for the brief time that it is in WOT until the driver eases off the accelerator. The project considers alcohol fuels to be a solution to fuel shortages, environmental damage, and public health issues caused by traditional cooking in the developing world.
In order to meet all of these requirements as the engine components wear with age and use, the automobile manufacturers have decided that the engine cannot have fixed xlternative but must adjust to conditions and wear dynamically. This raises the volumetric efficiency of the engine and reduces the required work input in the compression stroke. For E10 it is about 0. Engines using high octane fuel can run more efficiently by using higher compression ratios.
It produces less overall emissions compared to gasoline. After fermentation, the mash is heated so that the ethanol evaporates. It is then also possible to use the energy efficiency of the diesel principle with ethanol. Of these methods, a third method has emerged and has been adopted by the majority of modern ethanol plants.
WOT requires an overly rich fuel mixture to ensure maximum combustion and to prevent the engine from getting too hot rich cooling and from fuel-starvation misfiring under heavy load.
Ethanol fuel – Wikipedia
At places with harsh cold weather, the ethanol blend in the US has a seasonal reduction to E70 for these very cold regions, though it is still sold as E Two of which were alcohols; methanol and ethanol [20]. Ethanol fuel in Brazil. When it’s E70 with an E85 sticker on it”.
