Environmental Concerns Of The Fuel Usage

Fuel efficiency in automobiles has become a topic of much discussion in recent years in the United States. This is due largely to the environmental devastation that fuel emissions cause, but it is also sparked by the rising fuel costs. Making cars with high fuel efficiency not only saves consumers money, but also will drastically reduce the pollution that is caused by emissions. Today automakers are putting a tremendous amount of effort into making their cars more fuel efficient, both to meet government regulations and to make their car more appealing to the consumer.

A large part of the alternative fuels boom has been a part of civilization for thousands of years: ethanol. The same substance that makes alcoholic beverages intoxicating is also a useful fuel. Ethanol’s potential as a motor fuel has been known since the first internal combustion engines were made; The Ford Model T was able to run on gasoline, ethanol or any mix of the two (Bettelheim 802).

Imagine a fuel that can reduce harmful emissions and boost domestic economy around the globe. A fuel that commit our working demand which must clean, sustainable and made from abundant resources. Methanol is that type of fuel, a globally accessible fuel that already widely used by many countries around the world and it’s making headline around the globe. Methanol is the simplest alcohol fuel and the source of energy for fuel cell. It’s also a basic chemical building block, used in the production of wide range of commodities which touch our daily lives from plastics, solvents to windshield washer fluid. Methanol is producing from wide range of raw materials including biomass, natural gas, coal and even pollution emitted from factories and power plants .Countries around the world already using innovative sources to produce methanol fuel like using the waste from paper production called black liquor to create diesel fuel replacement, byproducts of bio-diesel production are made into bio-methanol, Carbon cycle

Methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. Use of biofuels such as methanol for combustion process is associated with positive environmental impacts. Using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. In this paper, methanol was injected into combustion chamber of a ISM 370 HD diesel engine and exhaust emissions of this engine which took advantage of pure methanol were evaluated by using AVL FIRE CFD code software at four engine speeds (1200, 1400, 1600 and 1800 rpm). Additionally, influences of EGR mass fraction and various injection timings were investigated. For validation of simulation, in-cylinder mean pressure and rate of

Ethanol fuel has many positive features as an alternative to the use of liquid fuel. First, ethanol is renewable. A relatively safe fuel would show very few engine changes. Second, its energy density is much higher than with some of the other alternative fuels, such as methanol, which means there would be less volume required to go the same distance. With the third benefit of ethanol, it would be able to improve much of the agricultural economies by providing farmers with stable market crops, such as maize and sugar beets, and with

Since the invention of the internal combustion engine, car makers and consumers have been filling the gas tank with just that, gasoline. Starting out with leaded gasoline then slowly switching to unleaded gas in the late 1960s until catalytic converters, a new auto part which can only run on unleaded, were made mandatory in 1975. However over the past couple decades there have been a new contender in the fuel marketplace to power consumers’ cars. Ethanol is defined in World Book Student as “a type of alcohol found in alcoholic beverages and used as an automobile fuel” (Sheehan 1). Sometimes called ethyl alcohol or grain alcohol, has been an additive to gasoline since its introduction. The purpose was to reduce dependence on foreign oil,

“If you pick any car to own and drive, what car would it be?” Everyone wants to drive fast, sports, and expensive cars such as: Bugatti, Ferrari, GTR, etc. These cars are great cars, but people want them because it is a want and a luxury, not worrying about anything but their own desires. Cars have quite a few corresponding events just to drive them. These could include things like buying gas or paying for maintenance. This is a huge problem for people of any age. They could be high schoolers using their job to pay for their car, or adults having to commute far to get to their job. Another huge problem that cars help fuel is the bad environmental effects that are created by the emissions than gasoline cars release. There are some solutions to some problems people may be having dealing with their traditional, gasoline cars. The biggest solution to this problem is to would be to change the fuel source of the car. They can be changed to fuel sources such as: Propane, Hydrogen, Electric, Biodiesel, or Ethanol. The only problem faced when changing to these other fuel sources is that they are not high in demand. The demand in alternative fuels needs to increase instead of focusing mainly on gasoline cars to help keep the environment safe. Alternative fuels are not in demand right now, so there are not many stations to fuel up on the alternative gases. The increase in demand of alternative fueled cars will help keep the environment healthier, as well as giving people the perks

With the increasing costs, both financial and ecological, of fossil fuels, fuel efficiency in vehicles has become an increasingly important factor. Vehicle manufacturers and designers are exploring alternative fuels, with electric, hybrid and hydrogen-powered vehicles being looked at as viable alternatives. Solar power has been somewhat overlooked but has the ability to become widely used because it is both clean and economical. The advantages over fossil fuels are obvious: Solar power is renewable, cannot be exhausted and doesn’t cause pollution. Fossil fuels are becoming increasingly scarce and expensive. Solar seems like a logical alternative. As such, it is being considered by private companies and government think tanks as a partial

“Methanol,” frequently termed as wood energy is consumed as substitute energy. Such supple-energy automobiles can utilize M85 type of ‘methanol.’ This is a blend of eighty-five out of a hundred of methanol and about fifteen out of a hundred petrol. The other substitute energy is biofuel, which is based on vegetable oils or animal fats. It may also be produced from recycled oils from restaurants after being used for cooking. This calls for engine conversion so that they can burn biodiesel in its pure state (Adrian, 2007). ‘Biodiesel’ can be blended with petrol-diesel and get utilized in original locomotives. It is decomposable, and decreases contaminants (‘particulate’ substance, ‘carbon monoxide,’ and ‘hydrocarbons’) associated with the use of fossil fuels in vehicles. ‘Propane’ can also be used as substitute energy and it is a byproduct of “natural gas.” It is more consumed as energy for cooking and heating and it automobiles it produces fewer emissions than gasoline. Another substitute energy is hydrogen which is mixed with ‘natural gas’ to create substitute energy for vehicles designed with interior incineration locomotive capacities.

Diesel fuel is a mixture of alkane hydrocarbons (a compound containing hydrogen and carbon). These hydrocarbons are saturated, essentially meaning the fuel has a low density – this is important so that the vehicle using such fuel can operate efficiently (Energy Information Administration, 2013). Furthermore, alkanes are extremely combustible, ensuring sufficient burning of the diesel (Nave, R.). After observing these characteristics of diesel, it became essential to prove that alcohols too had properties similar to these (despite sources supporting the change from diesel to a combination of diesel and alcohol). Alcohols do have equivalent hydrocarbons (Chemical Industry, 2015). The alcohol molecule too contains oxygen contributing greatly to the act of combustion (Natural Resources and Environment Department). This property, together with its saturated nature

Alternatively ethanol could be used as a replacement for kerosene for use in a jet engine. The use of ethanol as opposed to kerosene would reduce carbon dioxide emissions, provided that a renewable energy source was used to produce crops and to distil fermented ethanol. In addition to this ethanol is a renewable source unlike kerosene thereby eliminating the concern of this source running out. Also the presence of oxygen in the ethanol molecule means that combustion is almost always complete.

In our world today diesel engines have become a substantial part of the society, being used in buses, trucks, locomotives, tractors, and so on. Scientist has been seeking ways of improving the efficiency of diesel engines by developing and testing alternative fuels. Recent studies explore the use of diesohol as a substitute to diesel. Diesohol are classified as “a mixture of diesel fuel and anhydrous alcohol blended using a chemical emulsifier,” (Environmental Protection Agency, 2003).However a major concern regarding diesohol is both alcohols and diesel have dissimilar physical and chemical properties. Alcohols due to it being an oxygenate proved to burn cleanly and easily, and produce decreased amount of soot and harmful emissions (Mithun Mohan,2015) .It is estimated its combustion is around 3000 kJ/kg (The Engineering ToolBox, Unknown),(Mitun Mohan,2015).The chemical equation for the combustion of alcohols :

In the early days of the automobile the steam engine was first fitted to a three wheeled vehicle, this was quickly replaced by the internal combustion engine, for in my opinion the practical reason of carrying fuel was easier in a liquid form rather than in the form of coal, wood and water. But ever since that day and especially ever since the 1960 's when laws were enacted for safety and for the environment automakers have been working to make the internal combustion engine work better and cleaner. This has brought us engines like the Flex Fuel engine. This is an engine that can run on gasoline but can also run on a high ethanol containing fuel. The issue with ethanol is that it produced a lot of octane, but not a lot of mileage, but because it is made from bio mass it is a greener form of fuel. Another way they have tried to make the engine better is through on demand cylinders. This is where a vehicle might have a v8 engine, but only uses those

Recently alternative fuels have been gaining popularity, especially here in the United States. The advantages of many of these fuels are being recognized with the rising cost of crude oil. Other countries around the world have been using alternative fuels for years, such as in Brazil where they have good feedstock for some fuels such as ethanol. Biofuels are also becoming cost effective with higher crude oil prices and can be completely renewable. The best thing about many of these alternative fuels is they can be readily used in standard internal combustion engines with little or no modification.

The performance and emission characteristics of engine will be studied using Castor seed oil, Mustard oil and Sunflower seed oil and their blends with diesel and by analyzing the
