Hi guys‚ my name is Betty. I am the lead of my group today. I am goanna talk about fuel prices. The issue of fuel is very complex. First‚ what is fuel? It is material such as coal‚ gas‚ or oil that is burned to produce heat or power. And these 3 energies occupy the major parts of fuel use. In the past few years‚ fuel prices went up rapidly. Each country is very sensitive on the price. What causes fuel prices to rise and fall? For instance‚ let us have a look at oil. There are two main reasons

AIRCRAFT FUEL SYSTEM The Purpose of a Fuel System A fuel system purpose is to store‚ transfer‚ and then to mix the fuel with air. The function of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air‚ vaporized‚ and burned to produce energy. As everyone knows‚ an internal combustion engine needs fuel to operate. Fuel is delivered to the engine by means of the fuel system. The fuel system must be self-contained and efficient so that it will properly energize

The Fossil Fuels Introduction Fossil Fuels are a non-renewable energy source. They are found in Earth’s depositions made over millions and millions years ago and are called non-renewable because they can’t be used again once they are spent. There are three major forms of fossil fuels: coal‚ oil and natural gas. COAL Coal is made up of carbon‚ oxygen‚ hydrogen‚ nitrogen and some amounts of sulphur -Three main types of coal: • Anthracite : the hardest and has the most carbon in

Alternative fuels‚ or at least the concept of it‚ has been around since the early days of the automobile. Alternative fuels such as biodiesel‚ ethanol and methanol‚ have been produced and used on a small scale for decades. They are now being rediscovered due to the rising cost of oil and the instability of world politics. The discovery of these fuels changed the face of the planet‚ but since day one people have looked for other fuels that improved over the course of history. Alternative fuel vehicles

Pre-heating Fuel for Charge Homogeneity to Improve Combustion Abstract – The idea of the automobile engine that people have is of one that is bygone. The automobile engine today is the pinnacle of engineering expertise‚ implementing the best of technologies and undergoing the best of manufacturing processes to make the closest possible achievement to perfection‚ from design to combustion. The art of perfection though starts much before the process itself. In case of the automobile engine

Fossil fuels Oil 1) Oil is produced in Middle Eastern countries‚ Saudia Arabia accounting for 13.1 per cent of the world total‚ America 16.5 per cent and Africa 12.1 per cent. Although the Middle East has a lot of oil reserves not much is consumed. North America‚ Europe and Eurasia consume a lot of oil. This is due to the countries being MEDCs so they will need more fuel as the demand is higher. 2) The factors which cause oil prices to increase are from supply shocks (the OPEC oil embargo

Abstract In this paper I will explore the use of ethanol as an alternative fuel source. Ethanol is considered a renewable energy resource; as it is derived from crops such as: corn‚ sugarcane‚ beets‚ as well as‚ other organic materials. The use of ethanol could decrease our dependence on ever depleting supplies of fossil fuels; such as oil. In this paper‚ I will briefly review how ethanol is produced in different parts of the world. I will also review several of the advantages of using ethanol

Helix Company produces several products in its factory‚ including a karate robe. The company uses a standard cost system to assist in the control of costs. According to the standards that have been set for the robes‚ the factory should work 780 direct labour-hours each month and produce 2600 robes. The standard costs associated with this level of production are as follows: | | Total | Per Unit of Product | Direct materials | $ | 53248 | $ 20.48 | Direct labour | $ | 8320 |

6 Ocober 2013 Fossil Fuels and Alternate Energy Sources In the early 1900s‚ fossil fuels were the primary source of energy‚ but in more recent times with reserves diminishing and global warming becoming a major issue‚ we are forced to develop alternate sources of energy. According to Melosi‚ Governments became aware of the effects of fossil fuels as early as the 1950s‚ and in an attempt to combat this‚ they passed laws to try and lower the amount of pollution it caused (The Automobile and
