Types of automobile engines: fossil fuel, electric, and hybrid

Download file to see previous pages... As scientists and engineers continue to experiment with other advanced technologies, it is possible that new engines will emerge in cars in a few years. For now, this research paper focuses on the current three technologies in the automobile industry: fossil fuel engines, electric engines, and hybrid engines. Fossil Fuel Engines Fossil fuel engine is probably the oldest technology in the automobile industry and has been used since the invention of motor cars. Fossil fuel engines run on fossil fuels including gasoline, diesel, natural gas, methanol, ethanol, petroleum gas, and so on (MacLean and Lave, 1). Fossil fuel engines are engineered such that they contain motors that are powered by the energy liberated by fossil fuels. This energy is used to turn the propellers of the engine hence enabling the car to move forward. However, this form of energy given off by the burning fossil fuels is extremely detrimental for the environment (MacLean and Lave, 5). When the fuel is burnt, the carbon given off by the fuel reacts with oxygen in the air to form carbon dioxide and water. Because one of the products of this chemical reaction is carbon dioxide, fossil fuel engines are considered to be damaging to the environment. This chemical reaction which takes place inside the fossil fuel engine gives off the green house gas, carbon dioxide. ...
Firstly, the fossil fuels are damaging to the atmosphere. They give off carbon, which then reacts with oxygen to form carbon dioxide. Carbon dioxide itself is very harmful to the ozone layer and the overall environment. Secondly, fossil fuels are of a limited nature. That is to say, these forms of natural resources have a limited supply, are non-renewable and can get exhausted. If we continue to use fossil fuels, there might be one day when the coming generations will not have any fossil fuel reserves left for them. Thirdly, fossil fuel engines are less cost effective and are expensive to refuel. Therefore, engineers are constantly looking for alternative ways of fueling cars which run on renewable energy sources that are less damaging to the environment. Electric Engines The reason for so much interest in electric engines is the nature of fossil fuel powered cars. Because electric engines in cars are less polluting that fossil fuel powered cars, they are being considered to replace all cars in cities. Engineers developed electric engines to be an environmentally friendly alternative to fossil fuel powered cars (Brain, 1). While fossil fuel engines run on damaging fossil fuels, electric engines use electric cells to run the engine. The electric engine contains an electric motor that runs of electrical energy rather than chemical potential energy. The electric motor gets its power or energy from a controller which in turn receives energy from the rechargeable batteries of electric cells (Brain, 2). The electric engine looks more like a wiring work and is generally more silent as compared to fossil fuel engines. The electric engine replaced some components which are typical of a fossil fuel powered car. For instance, the ...Download file to see next pagesRead More

Why government should make fossil fuel illegal
Government Should Make Fossil Fuel Illegal. Oil is a finite resource, its availability and price unstable. Oil also contributes to air pollution and enriches brutal dictatorships such as Libya and oppressive monarchies like Saudi Arabia. The ongoing unrest in both countries as well as throughout the Middle East has caused oil prices to rise and should again remind all countries to accelerate the implementation of alternative sources of fuel.
