Before we look at some alternative process' to help reduce or eliminate automobile pollution, we should try to understand how this occurs. This form of pollution is a direct result of the combustion process, also known as exhaust, and from fuel being evaporated into the atmosphere. The next step is to get a better understanding of the combustion process. The gasoline that we use to put into our cars are made of a mixture of hydrocarbons, hydrogen and carbon atoms. When we put the gasoline into our car, what is supposed ... ... middle of paper ... ...s, an alternative solution needs to be made.
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. However under normal driving conditions an engine will encounter lean conditions when cruising on the highway (better mileage) and rich conditions when accelerating (better power). The lean condition results in oxide and harmful nitrogen production. Rich conditions result in carbon monoxide production.
(Internal-Combustion Engine, 2007, p. 2) There are four main components to a small gasoline engine: the fuel system, the ignition system, the cylinder block, and the cooling system. The fuel system consists of the fuel tank, the fuel pump, and the carburetor. The fuel tank is where the gasoline is stored until it enters the carburetor. The fuel pump moves the gasoline through the fuel lines and into the carburetor. The carburetor is where the proper amount of air and gasoline is mixed to create the perfect explosion.
Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
Car pools, public transportation, or walking can reduce tons of nitrogen oxide emissions. Using less energy benefits the environment because the energy used comes from fossil fuels which can lead to acid rain. For example, turning off lights not being used, and reduce air conditioning and heat usage. Replacing old appliances and electronics with newer energy efficient products is also an excellent idea. Sulfur dioxide emission can be reduced by adding scrubbers to utility plants (Farnham, http://www.ems.psu.edu/info/explore/AcidRain.html).
Our current traditional fuel is gasoline. Gasoline is a mixture of a large variety of liquid hydrocarbons derived from the distillation of crude oil. When gasoline is burned, chemical bonds are broken down into more stable, lower-energy bonds in an exothermic reaction that releases significant amounts of energy. We use gasoline to run internal combustion engines. In an internal combustion engine, both gasoline and air are set into a chamber.
If it is annihilated, the whole planet, including the human race, will be erased along with it. This is one reason gasoline powered automobiles should be limited. Another reason privately owned gasoline powered vehicles should be limited is the depletion of the fossil fuel supply. People all over the world need petroleum, a fossil fuel, to fill their cars in order to get around. However, petroleum, like many other natural resources on this earth, is in short supply.
Carbon dioxide is caused by the consumption of fossil fuels only and it causes the possible greenhouse effect which has global warming as an outcome. Hydrocarbons are caused by the combustion of oil and petrol and it effects the environment with carcinogen. Carcinogen is a chemical agent that causes cancer. Sulphur dioxide is certainly one of the major atmospheric pollutants considered that it causes stinging eyes, lung damage, asthma, and acid rain. It is the result of coal-fired power stations.
Transportation such as cars, ferries, planes and more. When these vehicles are moving, some black gases will be pumped out through the gas pipe of the vehicles. It is gases that are unhealthy, and it will caused the greenhouse gases. And also, the industries around the world. It will produce Carbon Dioxide, which is the greenhouse gases from the factory when they burn the fossil fuels for energy as well as greenhouse gas emissions from some of the chemical reactions.
A fleet of vehicles will have far reaching impacts; perhaps best known by the general public is the impact on air quality. Air pollutants may be released in a number of ways: first through evaporation during fueling, second through tailpipe emissions while a car is running, and third through chemical reactions occurring with byproducts or unused components emitted into the atmosphere. (Motor vehicles and toxic air pollutants. 2008) Typical chemicals released include benzene, toluene, xylenes, diesel particulate matter, and volatile organic compounds.
