Methanol (m85) Gasoline has been the traditional fuel for most vehicles. It gives us a lot of energy when in our cars but sadly like any other material in the world, it has a limited supply and if we don’t find an alternative fuel we could be doomed. Such alternatives that have showed promising results are methanol (m85), in which we will discuss its advantages and disadvantages to gasoline. But first lets explain how gasoline works. Vehicles that use gasoline have a 4-stroke engine, which uses the gasoline to create an internal combustion to power the vehicle. These four strokes are intake, compression, combustion, and exhaust. During the first cycle a piston moving down takes in a mixture of gas and air. The piston then moves back up to its original position. During this compression cycle the high amount of cylinder pressure closes a valve, which brings the fuel and air. The engine then causes the piston to move upwards again which then compresses the mixture of air and fuel. In the next cycle the mixture of fuel is ignited by the spark plugs of the engine. When the fuel ignites it expands causing the piston to move back down creating the power to move the vehicle. The car exhausts valves then open which pushes the piston back up. This moves the fuel from the engine and restarts the whole process. Alternatives are being researched to replace this traditional fuel because of its harmful effects to the environment and because of its limited supply. One such alternative is methanol. Methanol is an alternative fuel, which can be produced from biomass, coal or natural gas. Since methanol does not have any color when it burns it is usually mixed with gasoline to create a 85% methanol and 15% gasoline. Another reason it... ... middle of paper ... ...dy being used by many race are because it increases thermal effectiveness and power output. It is also currently being used in China and has replaced 5% of the gas demands. Taxi drivers who have switched report on saving from about $1500-$5000 .Not many people use it n the U.S for their regular vehicles because there is no broad network of m85 gas pumps throughout the US. Most gasoline station don’t want another fuel to compete with them with lower prices Even though gasoline gives more energy to a vehicle there is a limited supply. Because of the limited supply m85 should be used as a replacement since it can easily be created from biomass and will also diminish our need on foreign independence. Even though gasoline has some advantages over methanol, the advantages of methanol outweigh its disadvantages. This is why we should switch from gasoline to methanol (M85)
MTBE, or methyl tertiary butyl ether, is an oxygenate commonly used in gasoline in America, Europe, and other countries throughout the world. It is a compound created by the chemical reaction of methanol and isobutylene that is added to gasoline because of its high octane level, allowing gasoline to reach the required octane levels and still include a gasoline component. In addition, because it is an oxygenate, MTBE helps gasoline more fully combust, which increases performance and reduces the amount of harmful pollutants such as CO, VOCs, NOx, and particulates released into the atmosphere from automobile exhaust [EFOA]. However, opposition has recently arisen against the use of MTBE in gasoline.
4. Exhaust: After the Air/Fuel mix has been burnt, the remaining chemicals in the cylinder (water and CO2 for the most part) must be removed so that fresh air can be brought in. As the piston goes back up after combustion, the exhaust valve opens allowing the exhaust gasses to be released. Ideally an engine takes in air (oxygen and nitrogen) and fuel (hydrocarbons) and produces CO2, H2O, and the N2 just passes through.
In the future the automotive industries will need alternative fuel sources, in turn that means they will need alternative engines in their automobiles. The engines found in their cars will have to be changed to fit the new fuels being made. They have many directions in which they can go concerning engine types and fuel types.
A Modest Proposal for Methanol and Ethanol Powered Cars "We need more stringent regulations on car emissions. Let's add MTBE to the fuel- that will reduce pollution. If people would just stop driving so much, pollution wouldn't be so bad. " People have long recognized the problems with the gasoline we use now. We have tried everything from putting regulations on emissions, to putting additives in the gasoline (only to discover later that MTBE got into the groundwater), to campaigns to get people off the road.
As we can see, the ingredients in the table above could be found in many common household items. Organic compounds such as methylamine, ethyl ether, benzene, methanol, and lithium aluminum hydride are extremely flammable so there is always a great chance for explosion to occur. Many methamphetamine labs in California and Missouri have used the Anhydrous Ammonia method or Shake and Bake method, a one simple step recipe where the yield of meth is around 95% and 10 minutes reaction period and it will need up to about 2 hours for the total time for preparation, production and cleaning up after the process is done (Garriott, 2011). The main ingredients for this production are pseudoephedrine (cold medicine), lithium, water, Coleman fuel, ice packs and an explosive device. Besides that, there are two other methods which are mainly used in methamphetamine production: the phenyl-2-propanone (P2P) method and the red phosphorous (red P) method (Scott & Dedel, 2006). However, Anhydrous Ammonia method is more popular because pseudoepherdrine can be easily obtained in cold medicine and the producing progress is quite simple and quick so this method can be applied in most of small scale clandestine methamphetamine laboratories (Scott & Dedel, 2006).

Gasoline is thought to be a helpful substance to all countries worldwide. However, the negative effects are far greater than the positive. A diversity of clean fuels is vital for the political, environmental, and economic health of America. Although gasoline is a product depended on by the United States of America and many other countries, the negative effects are unbearable, dangerous, and unnecessary due to the opportunity to use alternative fuels.
Cars are a fantastic invention. They make our lives even more carefree by getting us from place to place quickly while eradicating the need for legs altogether. There is no doubt that the benefits of driving from place to place are numerous. However, driving takes a whole lot of fuel, and everyone knows that fuel for cars isn’t the most plentiful (or cheapest!) of resources.
With a gasoline-fueled vehicle, buying gas to operate your car is a never-ending process. With the high price change of gasoline and oil, operating a gasoline-fueled vehicle tends to be very costly. While there are some types of small gasoline vehicles that get much better gas mileage than larger vehicles, even the most powerful gasoline cars will normally desire a contribution every month. According to some experts the only way a mainstream market for green vehicles wills materlize is with a pronounced and prolonged rise in fuel prices. (Buss, 4)
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
Fuel is drawn from the tank by an in-tank or chassis-mounted fuel pump. The fuel pump is the device that draws the fuel from the fuel tank through the fuel lines, to the fuel filter and then to the engine’s carburetor or injectors. There are two types of fuel pumps: mechanical and electrical. The mechanical fuel pump is bolted on the side of the engine block or on the side of the cover of the timing gear.
Fuel alternatives for the future are very important because, we need resources for life. We won’t have fossil fuels forever. It is important to start now. If we did not have any fuel alternatives how would the world be?
The general petrol, more commonly known as gasoline, is the most readily available source of power for one's car today. This is because gasoline is generally cheap and readily available. Gasoline is defined by Poltcor as a "petroleum-derived liquid mixture consisting mostly of aliphatic hydrocarbons and enhanced with aromatic hydrocarbons toluene, benzene or iso-octane to increase octane ratings, primarily used as fuel in internal combustion engines" (Poltcor 3). Most automobiles rely on this type of gasoline today. At gas stations, the general grades available are 87, 89, and 93. Each of the numbers represents the quality of the gasoline, 87 being the lowest, usually named Regular and 93 being the highest, usually named Supreme. Generally, the gas prices in the U.S. are cheaper than overseas. However, the gas price has been rising over past few years because of some issues with the Middle East. Even with this problem in the Middle East increasing the gas price regularly, the U.S. maintains its ranking as one of the cheapest places to get petrol, or gasoline. Although gasoline is cheap, it is demanded of every person to have an automobile and since automobiles rely on gasoline, the gasoline distributors have the advantage that the public is willing to pay high prices for gasoline, if it's the cheapest around.
As the piston rises, the pressure forces the poppet valve closed, and the mixture is compressed. Once the piston reaches its peak, the spark plug fires, igniting the compressed fuel causing the fuel to expand driving the piston downward. The exhaust valve opens after the piston reaches its lowest point. As the piston begins to rise, the exhaust fuel is driven out of the chamber. Large four-stroke engines tend to have more than one cylinder and often feature valves, fuel injectors, and turbochargers (Four Stroke
