Automotive Energy Consumption Essay examples -- Automobiles Transporta

Automotive Energy ConsumptionIn the United States, the railway car has come to be more than simply a means of transportation, only when also a status symbol and a symbol of autonomy. As a status symbol, automobiles have gotten larger and more expensive, with little or no regard for efficiency or environmental impact. With the proliferation of the Sport public-service corporation Vehicle (SUV), the average fuel efficiency of cars in the United States has begun to adjudicate from a peak over a decade ago. With technological and natural advances made in the last decade, it seems counterintuitive that average fuel economic governance had begun to decline. In beau monde to transform the advances made in native conflagration locomotive technology, one moldiness have a basic concord of engines and the fuels they burn.Four Stroke Internal Combustion EnginesThe 4-stroke, internal combustion engine at the heart of most automobiles on the road today is relatively inefficient an d produces high levels of pollutants. Even the most efficient gasoline burning at the stake internal combustion engines convert only 30-40% of the energy available in the fuel in to work. The rest of the energy is lost to heat, and is thrown away(predicate) into the environment by means of a heat exchanger (radiator) or through exhaust gases. Exhaust gases account for much of the pollution generated by internal combustion engines. Gasoline, for example produces Greenhouse gases such as nose candy Monoxide (CO), Carbon Dioxide (CO2), Nitrogen Oxides (NOxs) and releases unburned hydrocarbons (fuel) into the atmosphere. Greenhouse Gases are responsible for much of the depletion of the ozone layer, lead to world-wide warming and pose health threats to humans. In addition to these drawbacks, fossil fuels are not in endless supply and co... ...ssil fuel supplies. In order for any course of action to have widespread success, the people must back behind it. In the case of th is investigation, the citizens of the United States need to understand the necessity of conservation and the consequences of non-conformance. This may require government- imposed penalties to businesses and individuals who dont do their part to conserve. The exact details of such a system are not crucial at this moment, but rather a simple understanding of the outlook for the future. Without swift action in the about future to curb hydrocarbon consumption, both the environment and the world economy stand to suffer significantly.
